US president teased his 55 million Twitter followers about his latest action against Iran in the style of a Hollywood movie poster - a picture of him with the words: Sanctions are Coming.
But Donald Trump's taunt was not a joke - and it's expected there'll be real-life consequences for millions of Iranians.
The strict economic and trade penalties come into effect on Monday.
The White House says the aim is to force Iran to abandon what it calls its "destructive" behaviour in the Middle East.
But the move's been condemned by Russia, China, and many European allies. International investigators say Tehran is complying with the terms of the 2015 nuclear agreement.
As Trump keeps his promise to punish Iran, could the new tough measures end up hurting the Iranian people the most?
