Winning in Afghanistan is having a country that is stable enough to ensure that there is no safe haven for Al Qaida or for a militant Taliban that welcomes Al Qaida. That's really the measure of success for the United States.
As far as Iraq the important thing is that the Taliban is gone in Afghanistan three-quarters of the al-Qaida leadership is either dead or in jail and we now have Saudi Arabia working with us Pakistan working with us.
The overall physical demand that Iraq has is pretty amazing. It's 130 degrees and the soldiers are carrying about 100 pounds of extra gear. It's a pretty rigorous schedule and routine for them.
