But you've been working towards the wholesale butchery of your fellow Iraqi citizens for decades, so it doesn't bother you that the USA has broken the current regime's power and left increasing amounts of civil violence, corruption, and massive infrastructure breakdown in its wake. And besides, its common knowledge that US cluster bombs and artillery have friendly fire turned off, so they go straight through Kurdish babies without harm, only killing the big bad Sunni/Shiite insurgents.
You're also a mere 17% of Iraq's population, which means that pleasing you is obviously pleasing the whole of Iraq and the entire people of Iraq and the Muslim community at large.
