If Iraq Army attacks our troops, can we leave THEN?

Coalition forces handed over control of Iraq's armed forces command to the government Thursday, a move that U.S. officials have hailed as a crucial milestone on the country's difficult road to independence. from: Iraq Takes Military Reins From Coalition.

We have already had reports of Iraqi troops failing to support American troops under attack and sometimes even attacking American troops directly. And that was when those Iraqi troops were under American control. Now that the troops are technically under Iraqi control, what is to stop the Iraqi government from bowing to overwhelming pressure from their own population and starting a war against the American occupation forces?

Sure, the Iraqi army would be huge underdogs in a war against American troops, but people fighting for their own countries independence have proven to take on high odds in the past.

If American troops end up fighting the troops of the new Iraqi government, do you think George Bush, Dick Cheney and Donald Rumsfeld will allow our troops to come home? Or will it still be ''stay the course''? Is there ANY circumstance where they would be allowed to come home while George Bush was President? Any circumstance at all?
