"Secondly, to do what we have to do unilaterally, to be able to go after those threats as well, and we're doing that," he said. "And thirdly, to bring pressure on Iran to not engage in this kind of behavior. Because, very frankly, they need to know that our first responsibility is to protect those that are defending our country. And that is something we are going to do."
