Wow, I'm so sorry. My AP US History teacher was one of the only good teachers I had in my mediocre high school, and we chatted a few times after I graduated. :/ That book sounds interesting, though!

"One of the lessons of history is that anything, including summer thunderstorms, leads to Germany invading Poland."

When my partner and I did our central Europe trip, we joked that we were entering Germany from Poland and not the other way around, because otherwise we'd be invading Poland. :P
