Attack on Pearl Harbor

Description
This mod contains new decision/events to allow Japan to make the first strike against the United States.

The decision is only for Japan (obviously) and must be taken between December 1941 and February 1942. Also must be fascist government, at peace with USA and completed Strike South focus.

After activated, USA will lose 4 older battleships and few destroyers. Then it is war...

update?

If AI didn't attack, it probably doesn't have enough PP to take the decision. You can give AI some PP with console commands.

Continuation War, and Winter War when you think about it, would be perfect fit for "border conflict" mechanics that was introduced with Tiger DLC (and then just as swiftly abandoned).

Unfortunately, I hate the changes that Paradox is doing to HOI4 recently. Especially that stupid live service thing they call "war effort" (but it's more like "no effort"). I'm leaving HOI4 for good. There will be no more updates.

Sometimes the Ai decision didn't it happen, AI choose "Secure the Philippines" focu instead pearl harbor attack

This is a wonderful mod, thank you! Can't believe Paradox has not bothered to do this. Can you please create a Continuation War event for Finland to join Barbarossa? That would resolve another major oversight from Paradox .

I know of that battle, but sinking battleships was never really the main purpose of this mod. I was looking for a way a JAP player could enter the war with USA, that would also somehow benefit them. The Philippines focus is just plain stupid – there’s nothing to gain for JAP by declaring war early. And I don’t think that new update is going to change that.

So this mod is trying to emulate the intention behind Japanese attack. And also the consequences…

it was the Battle of Taranto of the English vs. Italian that inspired the Japanese to make their plan of attack on Pearl Harbor to neutralize the enemy fleet.

hello I find this mods great and very realistic which makes me think of the English who makes preventive port strikes on the Italian fleet, the battle of taranto in Italy in November 1940 they sank the battleship the tale di cavour and made out of combat the battleships the littorio and caio duilo and 2 destroyers and a heavy cruiser are damaged. it would be great to have the same events for this one thank you.
