Of course I knew that the original article title (which is not the same as the submission title here) had to refer to both the actual invasion (a rather brief military operation) and the badly mismanaged occupation of Iraq. I think it's a fair point to blame most of the deaths in Iraq caused by violence during the occupation on the occupation having occurred as it did. But that causation is less direct than battle deaths of civilians during the invasion. I by no means have anything good to say about how the occupation was planned and carried out--it badly hurt Iraq, and reflected very poorly on the United States compared to the postwar occupations of German or Japan. But on the other hand, for all I know if Saddam Hussein had died peacefully of natural causes in the same time frame, perhaps the country would have been every bit as internally violent.
