I have to quibble with one of his factual claims.
He says the US "has administered the death and homicide of over one million" citizens of Iraq. I believe he is referring to a thorough (and very good) study which calculated the excess mortality rate associated with the war and the resulting political instability in Iraq. That figure includes everyone who died as a result of sectarian violence between different groups of Muslims, as well as everyone who died due to lack of adequate nutrition or medical services. The portion of deaths made up by Muslim sectarian violence is huge, if I remember the study right. Maybe up to half.
Granted, that violence would not have erupted without the wanton, opportunistic US invasion of Iraq, but it's quite a leap to blame the US for "administering" the wanton, opportunistic murder of Sunnis by Shias, and vice versa.
