Days after the U.S. combat brigades left Iraq, the top commander of the U.S. forces said it would take a "complete failure" of the Iraq forces for the U.S. to resume combat operations.
General Ray Odierno said he is sure Iraqi troops are ready for the task of handling their country's security.
He added he wasn't ready to declare victory but says things are going well.
"I would say that we've made lots of progress here," General Odierno said. "I would say determine whether we've won the war or not we can see that in three to five years as we see how Iraq turns out."
On Thursday, the last of the combat brigades left, leaving only 50,000 American troops as trainers and teachers.
The General added he would like to see the Iraqi government step, the quicker the better.
