Iran “must stop sponsoring terror, halt its bloody proxy wars and permanently and verifiably cease pursuit of nuclear weapons,” Trump said in remarks at a meeting of leaders from the Gulf Cooperation Council hosted by Crown Prince Mohammed bin Salman in the Saudi capital. “They cannot have a nuclear weapon.”

U.S. President Donald Trump on Tuesday called Iran the "most destructive force" in the Middle East, blaming Tehran for instability across the region and warning that the United States will never allow it to obtain a nuclear weapon.
