President Trump warns the US could hit all of Iran’s electricity plants and even hints at strikes against the country's oil industry if no agreement is reached between Washington and Tehran.
"If there is no deal, we are going to hit each and every one of their electric generating plants, very hard, and probably simultaneously," he said.
"We have not hit their oil, even though that's the easiest target of all, because it would not give them even a small chance of survival or rebuilding. But we could hit it and it would be gone, and there's not a thing they could do about it."
Trump also said regime change was never the United States' objective in Iran.
"Regime change was not our goal. We never said regime change, but regime change has occurred because of all of their original leaders' death," he said.
"I can say tonight that we are on track to complete all of America's military objectives shortly, very shortly," Trump added.
But he also warned that strikes will carry on for a few weeks.
"We are going to hit them extremely hard over the next two to three weeks, we're going to bring them back to the stone ages, where they belong."
