Israeli Prime Minister Benjamin Netanyahu on Monday thanked President Trump for his “change in American policy on Iran,” and said he expects the U.S. and Israel to start taking more aggressive steps to rein in Iran’s support for terrorism.

“I believe that together we can roll back Iran’s march of aggression and terror in this region,” Netanyahu said in a joint statement with Trump in Jerusalem. “And we can thwart Iran’s unbridled ambition to become a nuclear weapons state.”
