Taliban and al Qaeda working together in Afghanistan

(CBS News) In an interview that aired Sunday night on "60 Minutes," CBS News' Lara Logan spoke with a Taliban commander, who claimed to be a bomb specialist trained by al Qaeda. He told "60 Minutes" that al Qaeda fighters are rushing into Afghanistan and that he has more than a dozen of them under his command, raising new questions about the strength of the Taliban and al Qaeda in Afghanistan and their role in the recent insider attacks against American troops in the region.

CBS News senior correspondent John Miller, spoke with "CBS This Morning" co-hosts on Monday about Logan's report and the situation in Afghanistan.

"Events in Pakistan have become so dangerous because of the drone strikes and the ability to locate them and take a lot of al Qaeda members out," Miller said, explaining the recent resurgence of al Qaeda in Afghanistan.

Miller claims in this way, the U.S. is a "victim of our own success" and that as a result of the U.S.-led targeted killings in Pakistan, "a lot of al Qaeda members have found their way back to Afghanistan and to the Taliban, who can put them to work."

Speaking to claims by U.S. counterterrorism officials that American troops have nearly eliminated al Qaeda forces, Miller said "One of the problems we have is we want all the lines to be neat ... what has happened is, as the organizations have broken down, because we have decimated them, groups of people who are still following the same narrative have spread around. The lines have gotten blurrier, but the narrative isn't."
