If I were the US I would’ve entered the war early, and rolled all the way to Moscow.
I suppose the lives of the entire Polish nation are a small price to pay for moral purity?
How many more years do you think WW2 would have went on had the Soviet Union collapsed in the absence of American lend-lease, and the UK and US been left to fight the Axis on their own? How many more years of the Holocaust burning ‘undesirables’ in the furnaces are acceptable to not have to sully your hands by joining with the Reds?
I have no doubt that the US and UK retained the material capacity to win (the will? That’s a different question). But there’s a multi-front, multi-million soldier deficit to be made up there, and the Nazis aren’t going to be idle in their new lebensraum. How many lives are worth playing “Both Sides” games with two legitimately gruesome but-in-no-way-reasonably-comparable authoritarian states?
