The first one was really harsh. That was a little bit to extreme IMO.
Bush might not be the smartest man on earth. But to "call" him the new generation Hitler is out of porportion.
The second one is difficult for me to judge because I wasn't in Vietnam, and I have no idea of what was going on over there. One thing is for sure thoug, one of those parts are lying. But who? I guess we'll never find out.
