You'd have to use excess death calculations to justify that equivalent. Over 20 years since 2003, the direct death toll in Iraq ia about 300K from "direct war related violence caused by the U.S., its allies, the Iraqi military and police, and opposition forces". watson.brown.edu/costsofwar/c... 1/

That's a much broader tally than US troops killing Iraqis in war, spread out over a much, much longer period, and would amounts to roughly half the proportion killed computing aggressively against a 2010 Iraq population for all of them. /fin
