His library was interesting, I wasn't sure what was going to be highlighted as the high spots of his presidency. Three things stood out as pivotal: the dropping of the atomic bombs on Japan, the Truman Doctrine/Marshall Plan, and the Red Scare.
While watching his bio film (narrated by David McCullough, not Martin Sheen who has done several others I've seen [I later found out McCullough wrote a book on Truman] I was struck by the similarities between Truman's challenges and those of our current president - then as now there are some serious partisan splits that ensures that no matter what the president does someone will be seriously unhappy. All the talk lately about how the two sides have in extreme directions really doesn't take history into consideration. Joe McCarthy anyone?
