The president is taking aim at not only Iran’s nuclear ambitions but “all of the bad behavior of Iran,” his White House press secretary Sarah Huckabee Sanders said earlier this month.

“Not just the nuclear deal as bad behavior, but the ballistic missile testing, destabilizing of the region, number one state sponsor of terrorism, cyber attacks, illicit nuclear program,” she said.

Trump has said that the nuclear agreement lifts crippling sanctions on the Iranian economy that return billions of dollars for it to use on its other activities in the Middle East. Pence said both he and Trump would never let the events of 1983 in Beirut happen again to U.S. interests at the hands of Iran and its Lebanese ally.

“This president will not sit idly by while the ayatollahs in Tehran plot more attacks like the horrific attack that we remember today,” he said.
