Accelerating the transition of military responsibility to the Afghan government, the United States agreed Sunday to hand control of special operations missions to Afghan forces, including night raids, relegating American troops to a supporting role and bringing the raids under Afghan judicial authority.

The deal clears the way for the two countries to move ahead with a more comprehensive partnership agreement that will establish the shape of American support to Afghanistan after the 2014 troop withdrawal deadline. And it resolves one of the most contentious issues for President Hamid Karzai, who faced intense domestic political pressure because of night raids’ deep unpopularity here, even as American commanders had insisted they were the linchpin of the military mission in Afghanistan. . .
