Oh please, don't try and pull the reverse argument (as is so commonly done) as justification. Who created the conditions to allow them to murder their own people? Which sons of bitches have been meddling in domestic M/E affairs as part of their foreign policy for over half a century? 'Primarily' from your quote only applies to the side with tanks, guns and bombs tbh. Everyone knows where to place the blame for that, and history will see to it that it remains a fact.
Either you are alluding to the fact that Saddam murdered his own people with a remarkable efficiency (or was it those peace loving Iranians who gassed the Kurds ?) or you are saying that these people are savages who need a firm hand of oppression to stop them slaughtering each other.
Can't quite decide.
