Wednesday on “The Alan Colmes Show,” Alan spoke with columnist and author Michael Weiss, who has co-written ISIS: Inside The Army Of Terror. The book details how ISIS evolved from a splinter group into an army of jihad.
Alan and Weiss discussed how ISIS came from a split with Al Qaeda, who is truly in charge of ISIS, and why a war with ISIS is coming and it will be “not just from the sky.”
