Germans always have an excuse.... and nazis assists have apologists. Stephen Ambrose said it best In “citizen-soldiers”. In all of World War II, the only time you were safe and treated decently was when an American Soldier came into your town.
I am the past person who would be an apologist for the Germans or the Nazis.
American know-how, American arms, the lend-lease agreement, and the Russian winter is what beat the Nazis.
