Analysis: The two reasons for Trump's ambiguity on Iran - and why his base is split
We just heard from Donald Trump, who said he may or may not authorise US strikes on Iran - see our 15.02 post.
Trump told reporters Iran has reached out to his administration, though he went on to say it's "late" to be talking.
He's keeping the ambiguity going, our US correspondent Mark Stone said, and there are two potential reasons for that.
"The first is he wants to keep everyone guessing," Stone says.
"It is useful to keep everyone guessing because that creates this sense of jeopardy.
"It means that the Iranians don't quite know where they stand, don't quite know what he's going to do. No one does."
But that ambiguity is also "inevitable", Stone said, because he believes the president "doesn't know what to do".
"So, it's useful to him to be able to say, you know, I might do this, I might do that," Stone added.
"But that's also because he doesn't know what he is going to do next. And he is in a real bind."
The forever wars
That's because Trump ran his campaign as a man who will stop the wars.
"And yet now he finds himself on the precipice of being forced by Israel, effectively, to join a new war," Stone said.
But, domestically, he is being pulled in different directions, with highly influential figures in the MAGA movement speaking out against intervention, such as Tucker Carlson and Marjorie Taylor Greene.
He's also got more traditionalist Republicans, such as Ted Cruz, saying the US must take this opportunity and take Iran out now.
"This is a huge, huge domestic challenge for Donald Trump, and it doesn't just threaten to split his base, it is splitting his base," Stone said.
"It's useful to be unclear about what he might do, but it is also because he has no idea himself, I don't think, what to do next."
