What if Nazi Germany did not invade Poland?

“largely due to American aid”: Largely a legend. In 1941, first German defeat in front of Moscow, USA is even not at war… And the production is not a full speed, so they have even problem to supply the UK.

At the risk of opening the Lend-Lease can of worms (not my intention), the 1941 and 1942 contributions of LL were minimal. But by 1943 through 1944 the contributions were simply staggering in amounts. The Soviets owed their battlefield mobility largely to US trucks, food supplies, and fuel. Without LL, the Soviets probably fight the Germans to a standstill...and stalemate on the Eastern Front rears its head.

And that would make the whole discussion of starting ww3 over Poland rather mute, IMHO....

While the Soviets did the majority of dieing in WW2 they still had more where that came from.

While the first part of that statement is certainly true, the part about having manpower reserves in 1945 is questionable.

The US would have had to "carry the ball" for the Eastern war, and I don't think the population would have stood for it.

This, I believe, is the crux of the matter. Nazism had been beaten, Hitler was dead, and America had done its duty. Now it was time to go home.

We've already discussed potential ww3 scenario to death

Certainly a lot of good information presented there (and some not so good). But I think, in the end, ww3 didn't happen there and then more for political reasons than material ones...(my humble opinion, of course).
