How many bodies does a war crime make?

I seldom agree whole hartedly, or even half hartedly, with Air America's "The Majority Report" I think that are a bunch of simple minded political hacks most of the time. However Sam Seeder was right on the money chewing out one neo-con who called up.
The man called up to say that he had read that only about 8,000 Iraqi civilians had been killed by US bombs and errant bullets. He said that clearly the 100,000+ figures were cooked.
Sam, to his credit and my admiration, spoke up quite elequently that even if only 8,000 civilians had been wrongly killed that was god awful enough. 8,000 people get killed not because they hated America, or were terrorists, or were in league with Sadam, but only because they happened to be in our way.
After the exchange, where the neo-con equated 8,000 dead people as being "not relavent". I did a little fact checking.
According to DOD, American Red Cross, and a host of others here is the low down. In getting Sadam out and us in, our actions resulted in the deaths of a recorded 7,340 civilian deaths. That was up until around June of 2003. Currently the Iraqi government itself says that around 30,000 civilians have lost their lives, most of that number died, not from insurgent attacks alone, but from getting caught in the crossfire between insurgents and US and Iraqi armed forces. These people would have all been alive if we did not feel it necessary to invade Iraq.
Maybe the terrorits that killed 2,900 civilians on 9/11 thought them "not relavent". What are the lives of a measily 2900 civilians, or 8000 civilians, or 29,000 compared to the struggle to rid the world of the "evil doers"?
