Forum:Would it be Plausible for Japan to invade america with USSR support circa WW2?

I'm working on a alt history where Churchill and Hitler sign an alliance in 1932 and that Japan and Russia become partners shall we say.

So I am curious would it have been plausible if Japan had the support from Russia would they of been able to of invaded USA and where would be the best point of entry; I know you have the options of Alaska however i see that as too obvious. Would there of been anywhere they could of landed on the west coast with little resistance or would it of been literally impossible to do. I want my alt history to be at least a plausible one before i even decide to start putting it up.
