I must disagree about the European Theater during WWII. We may have been there for a just cause and in self defense, but there were some not so just actions taken. Dresden, for example. I think in the grand scheme of war, it's impossible not to violate the dignity of other people. War is too emotional, too brutal, too intense for people to keep cool 100% of the time, if not much less. That said, I do think war is sometimes necessary for the greater good. No comment on Iraq.
