During defense summit in Pa., Trump threatens that Iran ‘better behave’

A major threat from Iran to the Middle East as the U.S. ramps up strikes: Iran's military warned it would destroy "all the infrastructure in the region" if President Donald Trump goes through with launching attacks against Iran's power plants and bridges. Trump said the U.S. would do that next week if Iran doesn't get back to the negotiating table. During his visit to Carlisle, Pennsylvania, on Wednesday, he threatened to finish them off.
