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.
In searching for a rationale to go to war, Bush settled on the notion of Saddam as an incarnation of evil, basically, and convinced himself that Saddam was fundamentally Adolf Hitler reborn. I think his feelings towards Saddam were in fact quite genuine and quite legitimately hostile. He was not play acting.
The people who write official histories for the Army believe that a generation needs to pass before you can tackle the official history. It's useful to have some distance. Sources become available. Passions cool. It allows an opportunity to make some real assessments and judgments about personalities and characters.
I conduct very few interviews with veterans. The contemporaneous, or near-contemporaneous, record for WWII is so spectacularly deep that latter-day recollections are largely unnecessary for a historian. Of course, in considering any account, I'm looking for additional sources that can confirm or enlarge that version of events.
