Re: Looking for a book: period between WWI & WWII
Most good comprehensive World War II books cover the run-up to war. For a better look at the Europe of the 1930s, I'd recommend William Shirer's books. "Rise and Fall of the Third Reich" is one of the best books of all time, IMO, and spends hundreds of pages on how the Germany of 1919 ended up as Hitler's Germany. "Berlin Diary" recounts his personal observations in the period of 1934-1941 when he was a CBS Radio correspondent stationed there. "Collapse of the Third Republic" chronicles the period between the wars in France that left them so unready to face Germany again.
My library's a little short on the Pacific side of the equation; most of the pre-war info I know comes from the comprehensive war histories.
Not all who wander are lost
