Except that sanctions have, according to some reports, galvanized the Iraqi people against the West (whether or not that's the fault of Saddam - which I think - or the sanctions, it doesn't matter in the minds of the people).

Except that here we are invading their country without provocation (again, in the minds of the Iraqi people). We are destroying their way of life because we (evil America) feel like it.

Except that because of the nature of this war, and the stated intent, it will be necessary to go into the cities and fight amongst the streets, where casualties are necessarily higher. Imagine if another country invaded your country and killed all your neighbors in an attempt to overthrow your despotic leader. Now imagine that you wouldn't fight back, if only to make sure you wouldn't be killed as well.
