The least the US could do in Iraq right now is get out with honor. Start with accepting the Senate's provision on cruel and inhumane treatment of detainees--that's what Udai and Kusai were into, not Uncle Sam, I thought. End with securing the country and bringing the troops home.
Saddam Hussein never posed a threat to US citizens larger than North Korea or Iran, and wars should be for the sole purpose of protecting the citizenry. Al Qaida was not in Iraq; WMD would have been found by now--the US invaded March 2003.
This was an optional war; it just happens that this optional war, unlike Bosnia (which was a UN-supported, multnational effort), has been a disaster: ethnic discord, a suck of American lives and tax money, a failure of planning (H. Paul Bremer and the CPA's billions come to mind); the war actually enabled terrorism. The worst part is that this war has significantly weakened our military, more than Clinton ever did. Weapons contracts can't take the place of boots on the ground, and the Army's missing its quotas, or filling them with underperformers.
There's a difference between a "peacenik" and someone who thinks the military should only be put in situations with clear objectives. After Vietnam one would think we'd never again put our military in an unwinnable political situation. But Iraq is that.
