There's an interesting book called Aberration In The Heartland of The Real about Tim McVeigh (the OKC bomber) that talks about his role prior to the bombing on the front lines of the Iraq War and what he and his Bradley fighting vehicle unit did as they charged into Iraq:

They literally bulldozed thousands of fleeing and surrendering Iraqis and buried them alive.

It wasn't a war, it was a slaughter. The book ties this and other atrocities to the mindset that led to Tim McVeigh (and 2 others from his squadron) participating in the OKC bombing.
