Al-Qaida is degraded but not defeated. Analyst Colin Clarke assesses where the U.S. may be mapping out its future counterterrorism presence after withdrawing from Afghanistan.
A senior administration official said that all U.S. troops will leave Afghanistan by Sept. 11, the 20th anniversary of the terror attacks that prompted America's involvement in its longest war.
The American troop presence will decline in Afghanistan from 4,500 to 2,500, and in Iraq from 3,000 to 2,500. Senior military leaders reportedly oppose the move.
