A new video shows what looks like the largest and most dangerous gathering of al Qaeda in years.

 And the CIA and the Pentagon either didn't know about it or couldn't get a drone there in time to strike.

U.S. officials won't comment on that, but every frame of the video is now being analyzed by the United States.

In the middle of the clip, the man known as al Qaeda's crown prince, Nasir al-Wuhayshi, appears brazenly out in the open, greeting followers in Yemen. Al-Wuhayshi, the No. 2 leader of al Qaeda globally and the head of al Qaeda in the Arabian Peninsula, has said he wants to attack the United States. But in the video, he looks unconcerned that he could be hit by an American drone.
