> Too bad the UK and the US couldn’t have figured out a way to let Stalin and Hitler bash each others brains out for a few years before getting involved.
They did. The US didn’t have troops on the ground until late 42, and even then it wasn’t much compared to the scale of the ear in the East.
And yet Stalin remained in power and wound up grabbing half of Europe in 1945. That doesn't fit with what I was thinking.
