Well, using the current war in Iraq as a model, my understanding is that Saddam Hussein was responsible for upwards of 1.5 million deaths during the Iran-Iraq war (depends on who you think "started" it, but Iraq invaded first), and then there are couple of hundred thousand more in the Gulf war, and a few tens of thousands of Iraqis in internal issues after that. So if the U.S. has "only" been responsible for 600,000 casualties, then we're ahead of the game, correct?

There must be a better way to decide this sort of thing...
