"2. Ostensibly, the goal was to capture or kill Osama bin Laden but this wasn't done."

Not exactly true again is it Frank? To kill or capture Osama bin Laden was "One of the Goals" of the Afghan part of US-Operation Enduring Freedom forces. Now nobody knows for sure whether they were successful in this or not. Many including the Benezir Bhutto believe that Osama bin Laden was killed in Tora Bora in 2001, no "outsider" has met him since, and if the insurgency was winning to the extent that you obviously believe Frank, he most certainly would be a doing rather more talking about it.

US-OEF have about 23,000 troops in Afghanistan Frank, all other US troops their fall under NATO-ISAF Command and reading their UN mandate and mission statement you will find that there is no mention of Al-Qaeda; Osama bin Laden or even the Taleban. The mission of ISAF is the reconstruction of Afghanistan and the training of Afghan National Security Forces.
