Former U.S. Ambassador to Iraq Ryan Crocker was on “Hannity” to discuss the growing threat of ISIS.

“ISIS is not a mystery,” Crocker said, explaining that its predecessors were al Qaeda in Iraq. “They wanted Mosul then. We denied it to them. They just kept at it. So you don’t really need complex intel briefs to figure out the landscape there. They have been very consistent in what they are trying to do. Now they are succeeding. Now it is time for us to stand up, as Charles Krauthammer says. We had better lead this, I think others will fall in behind us, but we had better get after this and get after it now.”

Sean Hannity noted that American soldiers have fought for and died in cities that have now fallen to ISIS.

“Did they die for something worthwhile that we just gave back?” Hannity asked, saying that he would be very angry if he was the father of a fallen soldier.

“We didn’t finish the job,” Crocker said. “We’re not actually very good at finishing jobs.”
