This is Intelligence Matters with former acting director of the CIA, Michael Morrell.

Your mission is ours.

What happened for the rest of 2000 and even leading into 2001 was a skepticism of all of our warning.

This is the last in a series of episodes we were producing to commemorate the 20th anniversary of 9, 11 in this series.
