Would you say the Iraqi Shias are ungrateful?

I can't understand why they are not parading the streets and rejoicing at the fact that we Invaded, Killed and Occupied their land. It is beyond me that a nation is not grateful that their sovereignty has been attacked, their Oil stolen and their towns separated by giant walls, Israeli style.... They are so ungrateful that we managed to kill a million of their citizens, made evacuees of several more millions and tore away the fabric of their society... all for freeing them from a Dictator... strange people.
