Challange -> Operation Downfall 1943-44

Decimate the ijn at all those major battles. Have the soviets perform better agianst germany and have USA/USSR relations better to get the soviets to attack japan earlier.

Of course thats a bit ASB as there is little chance of the soviets beating germany faster and having left over troops in the east. It is possable to beat the IJN though.
 
Have the Germans and the Japanese not declare war on the US. Thus all US resources would be used in the Pacific War.
 
It could happen if there was an "Asia First" instead of "Europe First" approach. The only way I could see that happening is if Germany avoid war with the US. There are several ways for this. One being if Britain sign armistice in 1940. Another being if Hitler delayed Barbarossa.

I've became interested in the whole Operation Downfall thing myself are you writing a time line or something
 
You could have US naval intelligence pick up the Japanese Fleet on its way to Hawaii, or maybe just a chance sighting that lets the cat out of the bag. If the USN manages to keep the Japanese in the dark about it they could mobilize the Pacific Fleet and turn the tables on the IJN which would mean a very quick end to aspirations of the Japanese Empire. However I am not farmiliar with the numbers at the time, so maybe even in a standup fight the IJN would whip the USN.
 
DQ the problem is which do you build in 1943 DE's or landingcraft you can not build both because shortiges of motors for them .Also we were still building th warships to fight the IJN and most of them were just comeing out late in 1943 and most came out by 1944 . Rember also the US navy Had to build its support forces and man them also .
 
Slight error I meant Germany and Italy not declaring war on the US. If that happen then all of the military resources of the US would be concentrated on the Pacific war. There would be no lend lease add to the soviets and perhaps less to the British. This would mean that US industrial might would be concentrated on the Pacific war. Landing craft that were sent to Europe for operations in 1942-43 would be available for operations in the Pacific.
 
You need to have the British perform a lot better in this ATL as well.
Not allowing Japanese expansion in South East Asia would work miracles.

This however means that the British need more resources in the Pacific, which itself means that something has to change in Europe as well.
Perhaps the British negotiate a peace with the Germans in 1940 just after France and then shift forces over to the Far East?

It would surely be a bigger gamble for them, now that the British can bring in more forces to South East Asia.
But in order for this to happen, one can have the Germans perform better in the East in 1941, taking Moscow in autumn 1941 (since they lost less aircraft + troops in 1940/1941 without having to fight the British). This would let the Japanese believe than in the long run (after the Soviet Union is beaten) the Germans can link up with them and in the end be drawn into the conflict, should the short envisioned campaign in South East Asia fail.


The Japanese attack, they mess up and the whole war is accelerated...
