My reading of 1945 tells me that we ended up making a shameful deal with Stalin, under pressure from Roosevelt to do so, giving the Soviet tyrant the very 'free hand' in central Europe that we had impotently sought to deny Hitler. The difference was that by then we had sacrificed huge numbers of lives, all our wealth and our Empire. For what? If we had stayed out of power struggles in which we had no power, there'd have been no need to make a deal with Hitler, or Stalin either.
