Not really, most Republicans now realize we should have stayed out of WWII in Europe. Hitler would have crushed the USSR and hundreds of millions of lives would have been saved.

Staying out would not have been sufficient to ensure the defeat of Stalin, but it would definitely have meant someone besides the USA got the first nuke, and also meant that the USA wasn't defending its interests in the Pacific.

After the war, the British Empire (under either the British or the Axis depending on how that fight went) may well have been turned against you directly as a way to recoup losses, and regardless of which of Axis or USSR (or the British) won, someone would have gotten the magnetron and the rockets and the nuclear explosives, and it wouldn't have been the USA.

Right, this nonsense. Whitewashing Holocaust apologist with hypotheticals about Hitler’s Europe about as credible as their budget projections.
