Perry: I Have No Doubt There Are ISIS Cells In The U.S.

Wednesday on "The Alan Colmes Show," Alan spoke with former Defense Secretary William Perry, who has written a book detailing his life in international politics in the nuclear age called My Journey At The Nuclear Brink. Secretary Perry told Alan that after the Paris attacks he has no doubt there are ISIS cells in the United States and the biggest concern should be stopping terrorists threats at home.

Former Secretary Perry and Alan also discussed why ISIS' plans include a weapon of mass destruction, why Perry supports the Iran deal, and how close the United States and Russia have come to a nuclear war since the days of the Cold War.
