Operation Downfall

NOTE: This scenario is part of the World War II despite the fact it is part of the Cold War.

Operation Downfall was the proposed Allied plan for the invasion of the Japanese home islands near the end of World War II. The planned operation was canceled when Japan surrendered following the atomic bombings of Hiroshima and Nagasaki, the Soviet declaration of war, and the invasion of Manchuria. The operation had two parts: Operation Olympic and Operation Coronet. Set to begin in November 1945, Operation Olympic was intended to capture the southern third of the southernmost main Japanese island, Kyūshū, with the recently captured island of Okinawa to be used as a staging area. In early 1946 would come Operation Coronet, the planned invasion of the Kantō Plain, near Tokyo, on the main Japanese island of Honshu. Airbases on Kyūshū captured in Operation Olympic would allow land-based air support for Operation Coronet. If Downfall had taken place, it would have been the largest amphibious operation in history, surpassing D-Day.

Japan's geography made this invasion plan obvious to the Japanese as well; they were able to accurately predict the Allied invasion plans and thus adjust their defensive plan, Operation Ketsugō, accordingly. The Japanese planned an all-out defense of Kyūshū, with little left in reserve for any subsequent defense operations. Casualty predictions varied widely, but were extremely high. Depending on the degree to which Japanese civilians would have resisted the invasion, estimates ran up into the millions for Allied casualties.

Indonesian National Revolution

The Indonesian National Revolution was an armed conflict and diplomatic struggle between the Republic of Indonesia and the Dutch Empire and an internal social revolution during postwar and postcolonial Indonesia. It took place between Indonesia's declaration of independence in 1945 and the Netherlands' transfer of sovereignty over the Dutch East Indies to the Republic of the United States of Indonesia at the end of 1949.

The four-year struggle involved sporadic but bloody armed conflict, internal Indonesian political and communal upheavals, and two major international diplomatic interventions. Dutch military forces (and, for a while, the forces of the World War II allies) were able to control the major towns, cities and industrial assets in Republican heartlands on Java and Sumatra but could not control the countryside. By 1949, international pressure on the Netherlands, the United States threatening to cut off all economic aid for World War II rebuilding efforts to the Netherlands and the partial military stalemate became such that the Netherlands transferred sovereignty over the Dutch East Indies to the Republic of the United States of Indonesia.

The revolution marked the end of the colonial administration of the Dutch East Indies, except for New Guinea. It also significantly changed ethnic castes as well as reducing the power of many of the local rulers (raja). It did not significantly improve the economic or political fortunes of the majority of the population, although a few Indonesians were able to gain a larger role in commerce.

Emfýlios Pólemos

The Emfýlios Pólemos took place from 1946 to 1949. The conflict, which erupted shortly after the end of World War II, consisted of a communist-dominated uprising against the established government of the Kingdom of Greece. The opposition declared a people's republic, the Provisional Democratic Government of Greece, which was governed by the Communist Party of Greece (KKE) and its military branch, the Democratic Army of Greece (DSE). The rebels were supported by Yugoslavia and the Soviet Union. With the support of the United Kingdom and United States, the Greek government forces ultimately prevailed.

The war had its roots in divisions within Greece during World War II between the communist-dominated left-wing resistance organisation, the EAM-ELAS, and loosely-allied anti-communist resistance forces. It later escalated into a major civil war between the Greek state and the communists. Fighting resulted in the defeat of the DSE by the Hellenic Army.

The war resulted from a highly-polarized struggle between left and right ideologies that started when each side targeted the power vacuum resulting from the end of Axis occupation (1941–1944) during World War II. The struggle was the first proxy war of the Cold War and represents the first example of postwar involvement on the part of the Allies in the internal affairs of a foreign country, an implementation of George F. Kennan's containment policy in his Long Telegram. Greece in the end was funded by the United States (through the Truman Doctrine and the Marshall Plan) and joined NATO (1952), while the insurgents were demoralized by the bitter split between the Soviet Union's Joseph Stalin, who wanted to end the war, and Yugoslavia's Josip Broz Tito, who wanted it to continue.

First Indochina War

The First Indochina War (generally known as the Indochina War in France, and as the Anti-French Resistance War in Vietnam) was fought between France and Việt Minh (Democratic Republic of Vietnam), and their respective allies, from 19 December 1946 until 20 July 1954. Việt Minh was led by Võ Nguyên Giáp and Hồ Chí Minh. Most of the fighting took place in Tonkin in Northern Vietnam, although the conflict engulfed the entire country and also extended into the neighboring French Indochina protectorates of Laos and Cambodia.

At the Potsdam Conference in July 1945, the allied Combined Chiefs of Staff decided that Indochina south of latitude 16° north was to be included in the Southeast Asia Command under British Admiral Mountbatten. On V-J Day, September 2, Hồ Chí Minh proclaimed in Hanoi (Tonkin's capital) the establishment of the Democratic Republic of Vietnam (DRV). In late September 1945, Chinese forces entered Tonkin, and Japanese forces to the north of that line surrendered to Generalissimo Chiang Kai-shek. At the same time, British forces landed in Saigon (Cochinchina's capital), and Japanese forces in the south surrendered to the British. The Chinese accepted the DRV under Hồ Chí Minh, then in power in Hanoi. The British refused to do likewise in Saigon, and deferred to the French, against the ostensible support of the Việt Minh by American OSS representatives. The DRV ruled as the only civil government in all of Vietnam for a period of about 20 days, after the abdication of Emperor Bảo Đại, who had governed under the Japanese rule. On 23 September 1945, with the knowledge of the British commander in Saigon, French forces overthrew the local DRV government, and declared French authority restored in Cochinchina. Guerrilla warfare began around Saigon immediately,[28] but the French gradually retook control of Indochina. Hồ Chí Minh agreed to talk with France but negotiations failed. After one year of low-level conflict, all-out war broke out in December 1946 between French and Việt Minh forces as Hồ Chí Minh and his government went underground. The French tried to stabilize Indochina by reorganizing it as a Federation of Associated States. In 1949, they put former Emperor Bảo Đại back in power, as the ruler of a newly established State of Vietnam.

The first few years of the war involved a low-level rural insurgency against the French. By 1949 the conflict had turned into a conventional war between two armies equipped with modern weapons, with the French supplied by the United States, and the Việt Minh supplied by the Soviet Union and a newly communist China. French Union forces included colonial troops from the empire - North Africans; Laotian, Cambodian and Vietnamese ethnic minorities; Sub-Saharan Africans - and professional French troops, European volunteers, and units of the Foreign Legion. The use of metropolitan recruits was forbidden by the government to prevent the war from becoming more unpopular at home. It was called the "dirty war" (la sale guerre) by leftists in France.

The French strategy of inducing the Việt Minh to attack well-defended bases in remote areas at the end of their logistical trails was validated during the Battle of Nà Sản. French efforts were hampered by the limited usefulness of tanks in a forested environment, the lack of a strong air force, and reliance on soldiers from French colonies. The Việt Minh used novel and efficient tactics, including direct artillery fire, convoy ambushes, and anti-aircraft weaponry to impede land and air resupplies together with a strategy based on recruiting a sizable regular army facilitated by large popular support. They used guerrilla warfare doctrine and instruction developed from China, and used war materiel provided by the Soviet Union. This combination proved fatal for the French bases, culminating in a decisive French defeat at the Battle of Dien Bien Phu.

Milkhemet Ha'Atzma'ut

The 1948 Palestine war was fought in the territory of what had been, at the start of the war, British-ruled Mandatory Palestine. It is known in Israel as the Milkhemet Ha'Atzma'ut and in Arabic as a central component of the Nakba. It is the first war of the Israeli–Palestinian conflict and the broader Arab–Israeli conflict. During the war, the British terminated the Mandate and withdrew, ending a period of rule which had begun in 1917, during the First World War. Beforehand, the area had been part of the Ottoman Empire. In May 1948, the State of Israel was established by the Jewish Yishuv, its creation having been declared on the last day of the Mandate. During the war, around 700,000 Palestinian Arabs were displaced.

After the war, the former territory of the mandate was divided among the State of Israel, which captured about 78% of it, the Kingdom of Jordan (then known as Transjordan), which captured and later annexed the area that became the West Bank, and Egypt, which captured the Gaza Strip, a coastal territory on the shores of the Mediterranean Sea, in which the Arab League established the All-Palestine Government.

The war had two main phases, the first being the 1947–1948 civil war, which began on 30 November 1947,[19] a day after the United Nations voted to adopt the Partition Plan for Palestine, which divided the territory into Jewish and Arab sovereign states, and an international Jerusalem (UN Resolution 181). Partition was accepted by the Jewish leadership, but rejected by Palestinian Arab leaders and the Arab states. This phase of the war is described by historians as the "civil", "ethnic" or "intercommunal" war, as it was fought mainly between Jewish and Palestinian Arab militias, supported by the Arab Liberation Army and the surrounding Arab states. Characterised by guerrilla warfare and terrorism, it escalated at the end of March 1948 when the Jews went on the offensive and concluded with their defeating the Palestinians in major campaigns and battles, establishing clear frontlines. During this period the British still maintained a declining rule over Palestine and occasionally intervened in the violence.

The British terminated the Mandate at midnight at the end of 14 May 1948. On that day, the last remaining British troops and personnel departed the city of Haifa and the Jewish leadership in Palestine declared the establishment of the State of Israel. This was followed the next day by the invasion of Palestine by the surrounding Arab armies and expeditionary forces.

The invasion marked the beginning of the second phase of the war, the 1948 Arab–Israeli War. The Egyptians advanced on the southern coastal strip and were halted near Ashdod; the Jordanian Arab Legion and Iraqi forces captured the central highlands of Palestine. Syria and Lebanon fought several skirmishes with the Israeli forces in the north. The Jewish militias, organised into the Israel Defense Forces, managed to halt the Arab forces. The following months saw fierce fighting between the IDF and the Arab armies, which were being slowly pushed back. The Jordanian and Iraqi armies managed to maintain control over most of the central highlands of Palestine and capture East Jerusalem, including the Old City. Egypt's occupation zone was limited to the Gaza Strip and a small pocket surrounded by Israeli forces at Al-Faluja. In October and December 1948, Israeli forces crossed into Lebanese territory and pushed into Egypt's Sinai Peninsula, encircling the Egyptian forces near Gaza City. The last military activity happened in March 1949, when Israeli forces captured the Negev desert and reached the Red Sea. In 1949, Israel signed separate armistices with Egypt on 24 February, Lebanon on 23 March, Transjordan on 3 April, and Syria on 20 July. During this period the flight and expulsion of the Palestinian Arabs continued.

Chinese Communist Revolution

The Chinese Communist Revolution was a social and political revolution that culminated in the establishment of the People's Republic of China in 1949. For the preceding century, China had faced escalating social, economic, and political problems as a result of Western imperialism, Japanese imperialism, and the decline of the Qing dynasty. Cyclical famines and an oppressive landlord system kept the large mass of rural peasantry poor and politically disenfranchised. The Chinese Communist Party (CCP) was formed in 1921 by young urban intellectuals inspired by European socialist ideas and the success of the Bolshevik Revolution in Russia. The CCP originally allied itself with the nationalist Kuomintang party against the warlords and foreign imperialist forces, but the Shanghai Massacre of Communists ordered by Kuomintang (KMT) leader Chiang Kai-shek in 1927 forced them into the Chinese Civil War spanning more than two decades.

Early Nationalist military dominance forced the Communists to abandon their strategy of appealing to the urban proletariat, instead basing themselves in the countryside as advocated by Mao Zedong. Mao rose to become the Chairman of CCP during the Long March while the CCP narrowly avoided complete destruction. The Communists led by Mao once again formed a United Front with the Kuomintang to fight the Japanese occupation of China beginning in 1937. The CCP made effective use of situation to rebuild their movement around the Chinese peasantry. Following the Japanese surrender in 1945, China became an early hot spot in the Cold War. The United States continued to funnel large amounts of money and weapons to Chiang Kai-shek, but corruption and low morale fatally undermined the Nationalist army. The Soviet Union's decision to let the communists take control of Japanese weapons and supplies left behind in Manchuria, on the other hand, proved decisive. The Communists were able to mobilize a massive army of peasants with their program of radical land reform and gradually began winning open battles against the KMT. In 1948 and 1949 the Communist People's Liberation Army won three major campaigns that forced the Nationalist government to retreat to Taiwan. On 1 October 1949, Mao formally proclaimed the creation of the People's Republic of China.

Korean War

The Korean War was fought between North Korea and South Korea from 1950 to 1953. The war began on 25 June 1950 when North Korea invaded South Korea following years of hostilities between the two countries. North Korea was supported by China and the Soviet Union while South Korea was supported by the United States and allied countries. The fighting ended with an armistice on 27 July 1953.

In 1910, the Empire of Japan annexed Korea, where it ruled for 35 years until its surrender at the end of World War II on 15 August 1945. The United States and the Soviet Union divided Korea along the 38th parallel into two zones of occupation. The Soviets administered the northern zone, and the Americans administered the southern zone. In 1948, as a result of Cold War tensions, the occupation zones became two sovereign states. A communist state, the Democratic People's Republic of Korea, was established in the north under the rule of Kim Il Sung, while a capitalist state, the Republic of Korea, was established in the south under the autocratic leadership of Syngman Rhee. Both governments claimed to be the sole legitimate government of all of Korea, and neither accepted the border as permanent.

The years prior to North Korea's invasion of South Korea were marked by border clashes between the two countries and an insurgency in the South that was backed by the North. After failed attempts to stop the fighting and unify the Koreas, North Korean forces (Korean People's Army or KPA) crossed the 38th parallel on 25 June 1950, formally starting the war. The United Nations Security Council denounced North Korea's actions and authorized the formation of the United Nations Command and the dispatch of forces to Korea to repel it. The Soviet Union was boycotting the UN for recognizing Taiwan (Republic of China) as China, and the People's Republic of China was not recognized by the UN, so neither could support their ally North Korea at the Security Council meeting. Twenty-one countries of the United Nations eventually contributed to the UN force, with the United States providing around 90% of the military personnel, and represented the first attempt at collective security under the United Nations system.

After the first two months of war, the South Korean army (ROKA) and hastily dispatched American forces were on the point of defeat, retreating to a small area behind a defensive line known as the Pusan Perimeter. In September 1950, a risky amphibious UN counteroffensive was launched at Incheon, cutting off KPA troops and supply lines in South Korea. Those who escaped envelopment and capture were forced back north. UN forces then invaded North Korea in October 1950 and moved rapidly towards the Yalu River—the border with China—but on 19 October 1950, Chinese forces - the People's Volunteer Army (PVA) - crossed the Yalu and entered the war.[39] The UN retreated from North Korea following the PVA's First Phase Offensive and the Second Phase Offensive. China along with their North Korean and Soviet allies pressed their offensive, invading the South and capturing Seoul by early January of 1951. A UN force recaptured the city from them, and the communist forces were pushed back to positions around the 38th parallel following PVA's abortive Fifth Phase Offensive. After this, the front which was close to where the war had started stabilized, and the last two years were a war of attrition.

The fighting ended on 27 July 1953 when the Korean Armistice Agreement was signed. The agreement created the Korean Demilitarized Zone (DMZ) to separate North and South Korea, and allowed the return of prisoners. However, no peace treaty was ever signed, and the two Koreas are technically still at war, engaged in a frozen conflict.

Suez Crisis

The Suez Crisis was an invasion of Egypt and the Gaza Strip in late 1956 by Israel, followed by the United Kingdom and France. The aims were to regain control of the Suez Canal for the Western powers and to remove Egyptian president Gamal Abdel Nasser, who had just nationalised the foreign-owned Suez Canal Company, which administered the canal. Israel's primary objective was to re-open the blocked Straits of Tiran. After the fighting had started, political pressure from the United States, the Soviet Union, and the United Nations led to a withdrawal by the three invaders. The episode humiliated the United Kingdom and France and strengthened Nasser.

On 26 July 1956, Nasser nationalised the Suez Canal Company, which prior to that was owned primarily by British and French shareholders. On 29 October, Israel invaded the Gaza Strip and the Egyptian Sinai. Britain and France issued a joint ultimatum to cease fire, which was ignored. On 5 November, Britain and France landed paratroopers along the Suez Canal. The Egyptian forces, before they were defeated, blocked all ship traffic by sinking 40 ships in the canal. It later became clear that Israel, France and Britain had conspired to plan the invasion. The three allies had attained a number of their military objectives, but the canal was useless. Heavy political pressure from the United States and the USSR led to a withdrawal. U.S. president Dwight D. Eisenhower had strongly warned Britain not to invade; he threatened serious damage to the British financial system by selling the U.S. government's pound sterling bonds.

The Suez Canal was closed from October 1956 until March 1957. Israel fulfilled some of its objectives, such as attaining freedom of navigation through the Straits of Tiran, which Egypt had blocked to Israeli shipping since 1948–1950.

As a result of the conflict, the United Nations created the UNEF Peacekeepers to police the Egyptian–Israeli border, British prime minister Anthony Eden resigned, Canadian external affairs minister Lester Pearson won the Nobel Peace Prize, and the USSR may have been emboldened to invade Hungary.

Konfrontasi

The Indonesia–Malaysia confrontation or Borneo confrontation (simply known as Konfrontasi in both Indonesian and Malay) was an armed conflict from 1963 to 1966 that stemmed from Indonesia's opposition to the creation of the state of Malaysia from the Federation of Malaya. After Indonesian president Sukarno was deposed in 1966, the dispute ended peacefully.

The creation of Malaysia was a merger of the Federation of Malaya (now Peninsular Malaysia), Singapore and the British crown colonies of North Borneo and Sarawak (collectively known as British Borneo, now East Malaysia) in September 1963. Vital precursors to the conflict included Indonesia's policy of confrontation against Dutch New Guinea from March–August 1962 and the Indonesia-backed Brunei revolt in December 1962. Malaysia had direct military support from the United Kingdom, Australia, and New Zealand. Indonesia had indirect support from the USSR and China, thus making it an episode of the Cold War in Asia.

The conflict was an undeclared war with most of the action occurring in the border area between Indonesia and East Malaysia on the island of Borneo (known as Kalimantan in Indonesia). The conflict was characterised by restrained and isolated ground combat, set within tactics of low-level brinkmanship. Combat was usually conducted by company- or platoon-sized operations on either side of the border. Indonesia's campaign of infiltrations into Borneo sought to exploit the ethnic and religious diversity in Sabah and Sarawak compared to that of Malaya and Singapore, with the intent of unravelling the proposed state of Malaysia.

During Konfrontasi from 1963 to 1966, there was fighting between the Indonesian, Malaysian and Commonwealth forces along the long land border that Malaysia shared with Indonesia in East Malaysia. Many soldiers spent months patrolling the border, including Singaporean and Australian soldiers in Sarawak.

The jungle terrain of Borneo and the lack of roads straddling the Malaysia–Indonesia border forced both Indonesian and Commonwealth forces to conduct long foot patrols. Both sides relied on light infantry operations and air transport, although Commonwealth forces enjoyed the advantage of better helicopter deployment and resupply to forward operating bases. Rivers were also used as a method of transport and infiltration. Although combat operations were primarily conducted by ground forces, airborne forces played a vital support role and naval forces ensured the security of the sea flanks. The British provided most of the defensive effort, although Malaysian forces steadily increased their contributions, and there were periodic contributions from Australian and New Zealand forces within the combined Far East Strategic Reserve stationed then in West Malaysia and Singapore.

Initially, Indonesian attacks on East Malaysia relied heavily on local volunteers trained by the Indonesian Army. Over time, infiltration forces became more organised with the inclusion of a more substantial component of Indonesian forces. To deter and disrupt Indonesia's growing campaign of infiltrations, the British responded in 1964 by launching their own covert operations into Indonesian Kalimantan under the code name Operation Claret. Coinciding with Sukarno announcing a 'year of dangerous living' and the 1964 race riots in Singapore, Indonesia launched an expanded campaign of operations into West Malaysia on 17 August 1964, albeit without military success. A build-up of Indonesian forces on the Kalimantan border in December 1964 saw the UK commit significant forces from the UK-based Army Strategic Command. Australia and New Zealand deployed roulement combat forces from West Malaysia to Borneo in 1965–66. The intensity of the conflict began to subside following the coup d'état of October 1965 and Sukarno's loss of power to General Suharto. A round of serious peace negotiations between the two sides began in May 1966, and a final peace agreement was signed on 11 August 1966 with Indonesia formally recognising Malaysia.

Cuban Revolution

The Cuban Revolution (Spanish: Revolución cubana) was a military and political effort to overthrow the government of Cuba between 1953 and 1959. It began after the 1952 Cuban coup d'état which placed Fulgencio Batista as head of state. After failing to contest Batista in court, Fidel Castro organized an armed attack on the Cuban military's Moncada Barracks on July 26, 1953. The rebels were arrested and while in prison formed the 26th of July Movement. After gaining amnesty the M-26-7 rebels organized an expedition from Mexico on the Granma yacht to invade Cuba. In the following years the M-26-7 rebel army would slowly defeat the Cuban army in the countryside, while its urban wing would engage in sabotage and rebel army recruitment. Over time the originally critical and ambivalent Popular Socialist Party would come to support the 26th of July Movement in late 1958. By the time the rebels were to oust Batista the revolution was being driven by the Popular Socialist Party, 26th of July Movement, and the Revolutionary Directorate of March 13.

The rebels finally ousted Batista on 1 January 1959, replacing his government. 26 July 1953 is celebrated in Cuba as Día de la Revolución (from Spanish: "Day of the Revolution"). The 26th of July Movement later reformed along Marxist–Leninist lines, becoming the Communist Party of Cuba in October 1965.

The Cuban Revolution had powerful domestic and international repercussions. In particular, it transformed Cuba–United States relations, although efforts to improve diplomatic relations, such as the Cuban thaw, gained momentum during the 2010s. In the immediate aftermath of the revolution, Castro's government began a program of nationalization, centralization of the press and political consolidation that transformed Cuba's economy and civil society. The revolution also heralded an era of Cuban intervention in foreign conflicts in Africa, Latin America, Southeast Asia, and the Middle East. Several rebellions occurred in the six years following 1959, mainly in the Escambray Mountains, which were suppressed by the revolutionary government.

Cuban Revolution

The Portuguese Colonial War (Portuguese: Guerra Colonial Portuguesa), also known in Portugal as the Overseas War (Guerra do Ultramar) or in the former colonies as the War of Liberation (Guerra de Libertação), and also known as the Angolan, Guinea-Bissau and Mozambican War of Independence, was a 13-year-long conflict fought between Portugal's military and the emerging nationalist movements in Portugal's African colonies between 1961 and 1974. The Portuguese regime at the time, the Estado Novo, was overthrown by a military coup in 1974, and the change in government brought the conflict to an end. The war was a decisive ideological struggle in Lusophone Africa, surrounding nations, and mainland Portugal.

The prevalent Portuguese and international historical approach considers the Portuguese Colonial War as was perceived at the time—a single conflict fought in the three separate Angolan, Guinea-Bissau and Mozambican theaters of operations, rather than a number of separate conflicts as the emergent African countries aided each other and were supported by the same global powers and even the United Nations during the war. India's 1954 annexation of Dadra and Nagar Haveli and 1961 annexation of Goa are sometimes included as part of the conflict.

Unlike other European nations during the 1950s and 1960s, the Portuguese Estado Novo regime did not withdraw from its African colonies, or the overseas provinces (províncias ultramarinas) as those territories had been officially called since 1951. During the 1960s, various armed independence movements became active—the People's Movement for the Liberation of Angola, National Liberation Front of Angola, National Union for the Total Independence of Angola in Angola, African Party for the Independence of Guinea and Cape Verde in Portuguese Guinea, and the Mozambique Liberation Front in Mozambique. During the ensuing conflict, atrocities were committed by all forces involved.

Throughout the period, Portugal faced increasing dissent, arms embargoes, and other punitive sanctions imposed by the international community, including by some Western Bloc governments, either intermittently or continuously. The independentist guerrillas and movements of Portuguese Africa were heavily supported and instigated with money, weapons, training and diplomatic lobbying by the Communist Bloc which had the Soviet Union as its lead nation. By 1973, the war had become increasingly unpopular due to its length and financial costs, the worsening of diplomatic relations with other United Nations members, and the role it had always played as a factor of perpetuation of the entrenched Estado Novo regime and the nondemocratic status quo in Portugal.

The end of the war came with the Carnation Revolution military coup of April 1974 in mainland Portugal. The withdrawal resulted in the expulsion of hundreds of thousands of Portuguese citizens[24] plus military personnel of European, African, and mixed ethnicity from the former Portuguese territories and newly independent African nations. This migration is regarded as one of the largest peaceful, if forced, migrations in the world's history although most of the migrants fled the former Portuguese territories as destitute refugees.

The former colonies faced severe problems after independence. Devastating civil wars followed in Angola and Mozambique, which lasted several decades, claimed millions of lives, and resulted in large numbers of displaced refugees. Angola and Mozambique established state-planned economies after independence, and struggled with inefficient judicial systems and bureaucracies, corruption, poverty and unemployment. A level of social order and economic development comparable to what had existed under Portuguese rule, including during the period of the Colonial War, became the goal of the independent territories.

The former Portuguese territories in Africa became sovereign states, with Agostinho Neto in Angola, Samora Machel in Mozambique, Luís Cabral in Guinea-Bissau, Manuel Pinto da Costa in São Tomé and Príncipe, and Aristides Pereira in Cape Verde as the heads of state.

Milḥemet Šešet HaYamim

The Milḥemet Šešet HaYamim was fought between Israel and a coalition of Arab states (primarily Egypt, Syria, and Jordan) from 5 to 10 June 1967.

Military hostilities broke out amid poor relations between Israel and its Arab neighbours, who had been observing the 1949 Armistice Agreements signed at the end of the First Arab–Israeli War. Earlier, in 1956, regional tensions over the Straits of Tiran escalated in what became known as the Suez Crisis, when Israel invaded Egypt over the Egyptian closure of maritime passageways to Israeli shipping, ultimately resulting in the re-opening of the Straits of Tiran to Israel as well as the deployment of the United Nations Emergency Force (UNEF) along the Egypt–Israel border. In the months prior to the outbreak of the Six-Day War in June 1967, tensions again became dangerously heightened: Israel reiterated its post-1956 position that another Egyptian closure of the Straits of Tiran to Israeli shipping would be a definite casus belli. In May 1967, Egyptian president Gamal Abdel Nasser announced that the Straits of Tiran would again be closed to Israeli vessels. He subsequently mobilized the Egyptian military into defensive lines along the border with Israel and ordered the immediate withdrawal of all UNEF personnel.

On 5 June 1967, as the UNEF was in the process of leaving the zone, Israel launched a series of preemptive airstrikes against Egyptian airfields and other facilities, launching its war effort. Egyptian forces were caught by surprise, and nearly all of Egypt's military aerial assets were destroyed, giving Israel air supremacy. Simultaneously, the Israeli military launched a ground offensive into Egypt's Sinai Peninsula as well as the Egyptian-occupied Gaza Strip. After some initial resistance, Nasser ordered an evacuation of the Sinai Peninsula; by the sixth day of the conflict, Israel had occupied the entire Sinai Peninsula. Jordan, which had entered into a defense pact with Egypt just a week before the war began, did not take on an all-out offensive role against Israel. However, the Jordanians did launch attacks against Israeli forces to slow Israel's advance. On the fifth day, Syria joined the war by shelling Israeli positions in the north.

Egypt and Jordan agreed to a ceasefire on 8 June, and Syria on 9 June, and it was signed with Israel on 11 June. The Six-Day War resulted in more than 20,000 fatal Arab casualties, while Israel suffered fewer than 1,000 fatal casualties. Alongside the combatant casualties were the deaths of 20 Israeli civilians killed in Arab forces air strikes on Jerusalem, 15 UN peacekeepers killed by Israeli strikes in the Sinai at the outset of the war, and 34 US personnel killed in the USS Liberty incident in which Israeli air forces struck a United States Navy technical research ship.

At the time of the cessation of hostilities, Israel had seized Syria's Golan Heights, the Jordanian-annexed West Bank (including East Jerusalem), and Egypt's Sinai Peninsula as well as the Egyptian-occupied Gaza Strip. The displacement of civilian populations as a result of the Six-Day War would have long-term consequences, as around 280,000 to 325,000 Palestinians and 100,000 Syrians fled or were expelled from the West Bank and the Golan Heights, respectively. Nasser resigned in shame following Israel's victory, but was later reinstated following a series of protests across Egypt. In the aftermath of the conflict, Egypt closed the Suez Canal until 1975, eventually leading to the 1970s energy crisis and 1973 oil crisis due to the impact on oil deliveries coming to Europe from the Middle East through the Suez Canal.

Warsaw Pact Invasion of Czechoslovakia

On 20–21 August 1968, the Czechoslovak Socialist Republic was jointly invaded by four Warsaw Pact countries: the Soviet Union, the Polish People's Republic, the People's Republic of Bulgaria and the Hungarian People's Republic. The invasion stopped Alexander Dubček's Prague Spring liberalisation reforms and strengthened the authoritarian wing of the Communist Party of Czechoslovakia (KSČ).

About 250,000 Warsaw Pact troops (afterwards rising to about 500,000), supported by thousands of tanks and hundreds of aircraft, participated in the overnight operation, which was code-named Operation Danube. The Socialist Republic of Romania and the People's Republic of Albania refused to participate, while East German forces, except for a small number of specialists, were ordered by Moscow not to cross the Czechoslovak border just hours before the invasion because of fears of greater resistance if German troops were involved, due to public perception of the previous German occupation three decades earlier. 137 Czechoslovaks were killed and 500 seriously wounded during the occupation.

Public reaction to the invasion was widespread and divided, including within the communist world. Although the majority of the Warsaw Pact supported the invasion along with several other communist parties worldwide, Western nations, along with socialist countries such as Albania, Romania, Yugoslavia, and particularly the People's Republic of China (PRC) condemned the attack. Many other communist parties also lost influence, denounced the USSR, or split up or dissolved due to conflicting opinions. The invasion started a series of events that would ultimately pressure Brezhnev to establish a state of détente with U.S. President Richard Nixon in 1972 just months after the latter's historic visit to the PRC.

The Aylūl al-ʾAswad was an armed conflict between Jordan, led by King Hussein, and the Palestine Liberation Organization (PLO), led by chairman Yasser Arafat. The main phase of the fighting took place between 16 and 27 September 1970, though certain aspects of the conflict continued until 17 July 1971.

After the 1967 Six-Day War, Palestinian fedayeen guerrillas relocated to Jordan and stepped up their attacks against Israel and the occupied territories. They were headquartered at the Jordanian border town of Karameh, which Israel targeted during a battle in 1968, leading to a surge of Arab support for the fedayeen. The PLO's strength grew, and by early 1970, groups within the PLO began calling for the overthrow of Jordan's Hashemite monarchy, leading to violent clashes in June 1970. Hussein hesitated to oust them from the country, but continued PLO activities in Jordan culminated in the Dawson's Field hijackings of 6 September 1970. This involved the Popular Front for the Liberation of Palestine (PFLP) seizing three civilian passenger flights and forcing their landing in the Jordanian city of Zarqa, where they took foreign nationals as hostages and blew up the planes in front of international press. Hussein saw this as the last straw and ordered the Jordanian Army to take action.

On 17 September 1970, the Jordanian Army surrounded all cities with a significant PLO presence, including Amman and Irbid, and began shelling fedayeen posts that were operating from Palestinian refugee camps. The next day, 10,000 Syrian troops bearing Palestine Liberation Army (PLA) markings began an invasion by advancing towards Irbid, which the fedayeen had occupied and declared to be a "liberated" city. On 22 September, the Syrians withdrew from Irbid after suffering heavy losses to a coordinated aerial–ground offensive by the Jordanians. Mounting pressure from other Arab countries (such as Iraq) led Hussein to halt his offensive. On 13 October, he signed an agreement with Arafat to regulate the fedayeen's presence in Jordan. However, the Jordanian military attacked again in January 1971, and the Palestinians were driven out of the cities, one by one, until 2,000 fedayeen surrendered after they were encircled during the Ajlun offensive on 23 July, formally marking the end of the conflict.

Jordan allowed the fedayeen to relocate to Lebanon via Syria. Four years later, the fedayeen became involved in the Lebanese Civil War, which would continue until 1990. The Palestinian Black September Organization was founded after the conflict to carry out attacks against Jordanian authorities in response to the fedayeen's expulsion; their most notable attack was the assassination of Jordanian prime minister Wasfi Tal in 1971, as he had commanded parts of the military operations against the fedayeen. The organization then shifted its focus to attacking Israeli targets and later carried out the Munich massacre of 11 Israeli athletes. The events of Black September are said to have paved the way for a Jordanian–Palestinian divide.

Bangladesh Liberation War

The Bangladesh Liberation War was a revolution and armed conflict sparked by the rise of the Bengali nationalist and self-determination movement in East Pakistan, which resulted in the independence of Bangladesh. The war began when the Pakistani military junta based in West Pakistan—under the orders of Yahya Khan—launched Operation Searchlight against the people of East Pakistan on the night of 25 March 1971, initiating the Bangladesh genocide.

In response to the violence, members of the Mukti Bahini—a guerrilla resistance movement formed by Bengali military, paramilitary and civilians—launched a mass guerrilla war against the Pakistani military, liberating numerous towns and cities in the war's initial months. At first, the Pakistan Army regained momentum during the monsoon, but Bengali guerrillas counterattacked by carrying out widespread sabotage, including through Operation Jackpot against the Pakistan Navy, while the nascent Bangladesh Air Force flew sorties against Pakistani military bases. India joined the war on 3 December 1971, after which Pakistan launched preemptive air strikes on northern India. The subsequent Indo-Pakistani War involved fighting on two fronts; with air supremacy achieved in the eastern theatre, and the rapid advance of the Allied Forces of Mukti Bahini and the Indian military, Pakistan surrendered in Dhaka on 16 December 1971, in what remains to date the largest surrender of armed personnel since the Second World War.

Rural and urban areas across East Pakistan saw extensive military operations and air strikes to suppress the tide of civil disobedience that formed after the 1970 election stalemate. The Pakistan Army, backed by Islamists, created radical religious militias—the Razakars, Al-Badr and Al-Shams—to assist it during raids on the local populace. Members of the Pakistani military and supporting militias engaged in mass murder, deportation and genocidal rape, pursuing a systematic campaign of annihilation against nationalist Bengali civilians, students, intelligentsia, religious minorities and armed personnel. The capital, Dhaka, was the scene of numerous massacres, including the Dhaka University massacre. Sectarian violence also broke out between Bengalis and Urdu-speaking Biharis. An estimated 10 million Bengali refugees fled to neighbouring India, while 30 million were internally displaced.

The war changed the geopolitical landscape of South Asia, with the emergence of Bangladesh as the world's seventh-most populous country. Due to complex regional alliances, the war was a major episode in Cold War tensions involving the United States, the Soviet Union and the People's Republic of China. The majority of member states in the United Nations recognised Bangladesh as a sovereign nation in 1972.
