Pentagon Defends U.S. Policy Toward Syria

Key Senators pressed the head of the Pentagon on why the U.S. is not being more aggressive in trying to help rebels in Syria. But Secretary of Defense Leon Panetta and Joint Chiefs Chairman Martin Dempsey both insisted that Syrian air defenses make the prospect of airstrikes — like those used in Libya — very difficult. They also said the opposition in Syria is too fractured to risk sending in arms, which could end up in the hands of extremists.
