A Saudi Air Force lieutenant killed three people and wounded eight others in a shooting rampage Friday at a US Navy base in Pensacola, Florida. Esper said on "Fox News Sunday" that he had asked top defense officials to "make sure we're taking all necessary precautions" to make sure military installations were secure.
Esper said he had asked the Pentagon to "review what our screening procedures are" before soldiers from other countries come to the United States for training. He described those programs as "very important to our national security."
Esper also said the "only way forward" for the long-running war in Afghanistan "is through a political agreement" with the Taliban and the Afghan government. And he said the United States had reached a point in the Middle East that "we have deterred Iranian bad behavior."
