The American army between world wars after World War I had virtually disintegrated. It was a very small force, given largely to practicing cavalry charges on western outposts.
Hitler had a police state of the first order. And those who showed any sign of being weak-kneed faced prison or often summary execution. That prevented a lot of people who knew that the war was not going to turn out well for Germany from giving up.
The spring of 1942 was given over to a very impassioned, strategic debate about where we should first attack in counterpunching against the Germans and Italians. The British argued very persuasively on the part of Winston Churchill, prime minister, that this was a very green American Army, green soldiers, green commanders.
Almost everything about American society is affected by World War II: our feelings about race; our feelings about gender and the empowerment of women, moving women into the workplace; our feelings about our role in the world. All of that comes in a very direct way out of World War II.
Global war is a clash of systems, not just battalions biffing one another in some godforsaken forest.
There were almost 11,000 American soldiers killed in Germany in April of 1945, the last full month of the war. That's almost as many as died in June, 1944. Right to the very end, it was absolutely brutal.
