New dangers have emerged as U.S winds down opration in Afghanistan.

Obama made the case that the al Qaeda terror network in the Afghan and Pakistan region has been weakened but that new dangers have emerged as the U.S. winds down operations in Afghanistan after more than a decade of war triggered by the 9/11 attacks. Threats that have emerged come from al Qaeda affiliates, localized extremist groups and homegrown terrorists, like the two men suspected of attacking the Boston Marathon last month. The administration has been considering shifting control of lethal drone operations from the CIA to the military. One senior administration official said the "military is the appropriate agency to use force," not to rule out the range of options needed to deal with threats. By law, the military is not able to act in the covert way the CIA can in this particular arena and must answer to Congress. In his confirmation hearing for CIA director, John Brennan expressed a desire to move the agency away from paramilitary operations and back to traditional areas of espionage. "The CIA should not be doing traditional military activities and operations," he said. Obama rejected the idea of a global war on terror in favor of a more focused approach that will engage on specific networks of extremists who threaten the United States. The administration plans to avoid operations that will cause civilian casualties and wants to work with partners in its operations
