This comparison seems a bit silly, honestly, but here are some numbers for you.
About 1.1 million Iraqi civilian deaths under Saddam Hussein (600,000 if you don't count the war he started with Iran),
Source, between 75 and 125 per day.
Since we have been there, max of 17,285
Sourcebased not on actual body-counts but surveys of homes (as I understand it), about 27 per day.
As to American citizen deaths caused by our government in any similar fashion? I suppose if you stretch a bit you could count Ruby Ridge and Waco, for a total of 70+. I don't know an exact number (this is just from my memory of the events), but let's be generous and say 100, just for the sake of argument.
