In 2012, General Dempsey, General Petraeus directed the CIA, Secretary Panetta and Secretary Clinton recommended to the president to robustly arm and train the Syrian moderates. He says no.

The Taliban has not, in my judgment, in any significant way changed their fundamental goal and objective, which is to take over Afghanistan and return to running that country.
