In a misleadingly titled article ("Warner Calls for Pullouts by Winter") the Washington Post quotes exactly what the senior Republican moderate considers a significant change in course.
"I can think of no clearer form of that than if the president were to announce on the 15th that, in consultation with our senior military commanders, he's decided to initiate the first step in a withdrawal of armed forces," Warner said. "I say to the president respectfully, 'Pick whatever number you wish.' . . . Say, 5,000 could begin to redeploy and be home to their families and loved ones no later than Christmas of this year. That's the first step."
5000 troops brought home by Christmas. At that rate, we'll be out of Iraq in 32 years.
But only if the president really thinks we should do that, of course.
