Tweet from Trump an hour ago: No one has given the Islamic Republic of Iran as much of a big opportunity to reach an agreement as I have. In a way that is disastrous for themselves, they were unable to use it. Therefore, today I announce that the most forceful economic operation that has ever been carried out against any country will be launched! This will be an economic war and isolation on an unprecedented scale. Oil smuggling, swap lines, transfer of cash, exchange houses, registering ships, front companies — all of these must be stopped right now. You know who you are. These madmen have reached the end of the line, and these historic actions of theirs will paralyze their ability to spread terror across the world. Iran will never have nuclear weapons. Thank you for your attention to this matter. President Donald J. Trump
