Joint Chiefs of Staff Chairman Mark Milley predicted more violence in Afghanistan, while Defense Secretary Mark Esper said the road to peace would not be easy, both speaking at the Pentagon a little over a day after the United States signed a peace deal with the Taliban.

“This is going to be a long, windy, bumpy road, there will be ups and downs, and we’ll stop and start,” Esper said while standing alongside Milley on Monday morning.
