I think the Iran Iraq war produced for more KIAs than his annual total. In contrast the first Gulf War in 1991 which was not asymetrical had fewer casualties.

I think the case can be made that the total casualties in asymetrical warfare can be significant because they drag on so long. I have seen estimates that the Vietnamese suffered over a million casualties during the wars that led to the communist conquest.

Does his count include Pol Pot? How about the Sudan? It can be argued that the man made famine in the Sudan and the current one in Zimbabwe will kill significant numbers of people. We know that Stalin killed millions in the Ukraine and Mao killed millions in China using famine as a low cost genocide.
