If the deal we concluded is not sufficiently fair and beneficial, then very difficult times will begin for Iran, US President Donald Trump said. "We must sign an agreement, otherwise it will be very difficult for Iran. I will talk to the Iranians. If we can't come to an agreement with them, we will go to the second round. The second round will be really tough for them. I don't aspire to that," said Trump.
