First, deaths and genocide are different things. The CCP’s killing between 20 and 43 million people from 1959–1961 was incompetence not a genocide. Numbers of deaths are irrelevant the intent must be the systematic destruction of a people.

So sure the Iraq war combined combined with a sectarian civil war, and after effects from the breakdown of the economy and social order possibly reached a few hundred thousand deaths. But that’s by definition not a genocide. If you want an American genocide look back to what happened to Native Americans.
