Well, after the new SecDef is sworn in, we'll see how long it takes to reduce Fallujah to an overlapping field of bomb craters, kill Muqtada Al-Sadr (the leader of the terrorist Mahdi Army, who's running around loose in Iraq)), and take out Bin Ladin.
And we'll see if the JAG lawyers under SecDef Gates (assuming he's confirmed) are still waiting to prosecute (or at least investigate) practically every instance of troops killing too many Iraqis when they shoot back in a firefight.
