- Depending on who you talk to, Iraq has lost between 60,000 and 1.2 million killed.
A good comparison is Poland. The population prior to the war was roughly the same as Iraq, @ 34,849,000 compared to Iraq in 2003, which was according to the UN, 25,175,000. By the end of the occupation, which again is roughly about as long as America has been occupying Iraq, they had lost 5,600,000 people or 16.07% In contrast Iraq has lost 4.7 % of its population if one assumes 1.2 million extra deaths is correct.
The Germans killed 5 times as many people as the Americans. One could compare Iraq with occupied Norway, who lost "only" .042 of their population but then the Germans considered them fellow Aryans.
France lost 562,000 -- a "mere" 1.35% of their population, but then they, despite the fact that after the war, every second Frenchman claimed to have been a Maquis, did not resist to the extent that the Iraqis have.
If the low number is true, then, in historical terms, the Iraqi occupation has been kind indeed, even the higher number does not approach the Germans, forget the Mongols who tended to kill, well... everyone.
1.2 million dead Iraqis is still a stack of bodies approximately 189 miles high.
