Well yeah, who thinks you bring peace with war? There are ways we could have taken over Iraq peacefully, such as making it a protectorate and giving everyone health care (which would have been far cheaper than the war).
In fact, what you're saying is the second half of the traditional "We have to do something, and this is something, so we have to do this." fallacy. "Well, if bombing the the ungrateful fuckers didn't make them love us we're out of here."
No, you've got a lot of shit to fix before you get to quit.
