"Ours is a conditions-based strategy."

Our next C-in-C, Barack Obama:

Democratic presidential candidate Barack Obama said in an interview published on Saturday the size of a residual U.S. force left in Iraq after the withdrawal of combat troops would be "entirely conditions-based."

"It's hard to anticipate where we may be six months from now, or a year from now, or a year and a half from now."

"Barack Obama is ultimately articulating a position of sustained troop levels in Iraq based on the conditions on the ground and the security of the country. That is the very same position that John McCain has long held," said McCain spokesman Tucker Bounds.
