And thank God for Winston Churchill, who went against popular (and political) sentiment and refused to negotiate with Hitler for a truce when they seemed just about down for the count.
I cannot imagine how much harder our task would have been (in Europe AND the Pacific), if Britain had taken themselves out of the fight.
It would have ended up Nazi Europe vs Communist USSR. I have a feeling it would not have been pretty.
However, I also believe that if the US had not entered the “great war”, Germany would have won and there would have been no rise of Nazism. But at the end of the day, I’m not sure the world would have been any better off. The US would not be as powerful today - probably. We were the big winner of WWII.
