Iraq -- hypotheticals and reality

In a series of hypothetical questions about Iraq, Clinton and Obama both said they would pull out all troops if the Iraqi government requested it.
And, Obama said he would "reserve the right" to return if Al Qaeda was using the country as a base to plan more attacks against the United States.
Clinton, interrupted by commercials, was not given time to respond.
However, her joking appearance about Obama's speeches were presented. "I give her points for humor," Obama said.
