Stalin, you mean?He might have been crazy, but he was no fool.
Well, I think that Poland might have been in real trouble--Germany might have actually had some kind of army and there could have been some real trouble there.
1932 was a colossal mistake, and hard to understate. We would not have the Second Armenian Genocide with Turkish troops moving into the Caucusaus. There might not be a free Ukraine and free Belorussia. Last of all, I know this one sounds unbelievable, but I think Japan might have gone down by 1946. We know that the Japanese fought to the last man, all across the pacific. And there is lots of heroism over their beachhead in San Francisco with the Kwangtung Army--the first time the USA has been invaded since 1814. It would not have been an eight year war against Japan in the pacific.
ooc:? How could the Pacific War, which was a sideshow for the US in WW2 with the Europe-first policy, go almost twice as long with the entire US against Japan, which never had the capability to invade Hawaii, let alone the US?
IC: It's not really that the Japanese "invaded" the US, as much as tried a (disastrous) raid in a daringly stupid wave of attempted strikes across the West Coast and Panama, most of which sunk in the crossing. Clearly delusions of competence abounded the Japanese general staff officer who thought that a several hundred men would be enough to seriously damage any major US city, let alone Panama (one of the most heavily defended spots in the Western Hemisphere, after Pearl Harbor).
Also, I find it amusing that people claim that the US is not involved in the world. It's much more accurate to say that the US isn't involved in western Eurasia and Africa; the US is the leading character in the Americas, and a very major presence in East Asia. That's nothing to sneeze at.
In regards to the Japanese-American War a.k.a. "the War of the Pacific", I think the biggest threat was from the release of the "balloon bombs" by Unit 731, that caused the spread of "Japanese influenza" from 1943-1946. Even today, in places like China, India, Philippines, Indonesia, Vietnam, et al. most people are still demanding reparations and a formal apology. After 80 million deaths, I can't blame them...This is correct, except that actually storming Japan itself with those Kwangtung divisions might well take until 1948--and yes, talk about Shoestring operations...
