CHARLOTTESVILLE, Va. (WVIR) - A man who knows firsthand about the horrors in Afghanistan paid a visit to the University of Virginia's Miller Center Tuesday afternoon.

Former United States ambassador to Afghanistan Ryan Crocker spoke about the violence and threats of ISIS, the terrorist group trying to create an Islamic state.

Crocker sat in on a panel discussing whether or not the U.S. should be back on the ground in the Middle East after withdrawing in 2011, a move that left governments crumbling. He said withdrawing troops does not end wars; it just leaves the battleground to the enemies.

"What does that mean? For the first time since 9/11, we have a moral enemy who has the time, the space and the security to plan longer-range operations, and I can tell you, that's just what they're doing,” Crocker said.

His solution is to move forward and deploy more U.S. Army Special Forces. He says those Special Forces who can embed Iraqi leaders ready to fight are very important to defeating ISIS.
