Speaking by phone to NBC News, Trump didn't say whether he has decided to take action on Iran following previous threats of military intervention over a crackdown on protesters.

More than 2,500 people have died during nationwide protests in Iran over the past 17 days, activists said Wednesday.

Iran tension soars, Trump warns violence against protesters could bring an American intervention: "We are locked and loaded and ready to go."

Nevertheless, when Trump posted a message, “Iranian Patriots, keep protesting – take over your institutions!!! … help is on its way,” it felt as if this might be the moment of change. But the US pulled back – unready to act and uncertain of what intervention could achieve. Now the forces of repression are once again taking over Iran’s streets.
