America's CIA believes that the al-Qaeda terror network in Yemen poses a more serious threat to the US than those in its traditional stronghold of Afghanistan and Pakistan. The Washington Post reported quoting unnamed US officials that a fresh assessment of al-Qaeda's affiliate in Yemen has helped prompt Obama administration officials to call for an escalation of US operations there. These include a proposal to add armed CIA drones to a clandestine campaign of US military strikes. This is for the first time in recent years that the CIA has come out with the assessment that al-Qaeda in Yemen is more dangerous than those in Pakistan, where most of its top leadership including Osama bin Laden is believed to have been based. The officials, however told The Post that analysts continue to see al-Qaeda and its allies in the tribal areas of Pakistan as supremely dangerous adversaries. The daily reported that CIA has roughly 10 times more people and a resource in Pakistan than it does in Yemen.
