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.

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.

The U.S. Army records alone for World War II weigh 17,000 tons, and even the best historians have not done more than just scratch the surface. The story is such that 500 years from now people will be writing and reading about it.

I'm going to leave WWII. I considered and rejected doing something on the Pacific. Fourteen years is enough. I'd like to take on a different challenge and probably a different era. But it will be another war. It's what I do.

Global war is a clash of systems, not just battalions biffing one another in some godforsaken forest.

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.

If Ive vividly laid out the narrative, the reader will come to his own conclusions.
