President Donald Trump estimates Iran has retained about one-fifth of its missiles as he gave an assessment on where the country’s military stands as peace talks continue.

“Most of the drone factories have been knocked out, most of the launching pads have been knocked out, and most of the missile manufacturing areas have been knocked out. But they still have capacity. They have some missiles, they have some drones. I would say percentage-wise, maybe 21-22% of their missiles,” Trump said in a clip of his interview on NBC’s Meet the Press, set to air Sunday.
