The top U.S. commander in Afghanistan says the military alliance there has an "anaconda strategy" aimed "to squeeze the life" out of the Taliban and their allies.

Gen. David Petraeus said Tuesday the coalition's goal in Afghanistan is not to turn the war-torn country into a democratic republic like Switzerland, but raise its security and governance to a level when Afghans can take the lead.

He made the remarks after a NATO summit where the alliance embraced Afghan President Hamid Karzai's goal to have Afghan forces take control of security by the end of 2014.
