Too much travel.

When they say the meeting's scheduled for Tuesday, I said, Tuesday?

That's a long time from now.

Too much traveling takes too long, too expensive.

I'm a very cost-conscious person.

Mr Trump said that his decision didn't mean there would be a return to fighting.

So where does all this leave the negotiations?

I heard more from our North America correspondent, Peter Bowes.

Donald Trump was quite abrupt in his intervention, telling his team of negotiators that they were not going to make an 18-hour flight to Pakistan.

He said, we have all the cards, they can call us any time they want, referring to Iran.

But essentially, he is implying that he considers a long flight to Islamabad to, as he said, sit around and talk about nothing isn't worth the time and money.

I think it's probably fair to say that expectations were quite low to start with when this wasn't necessarily going to be the top team from the United States.

J.D.

Vance, the vice president who led negotiations two weeks ago, was always going to stay in Washington, but there were to be no talks.

And we know that Iran had been saying for at least a day or two that they were not inclined to take part in direct negotiations with the Americans anywhere.

So the day has achieved nothing.

So why is he doing this?

Because it appeared that the American team were set to go.

Well, Donald Trump seems to be taking a somewhat different attitude to the one that we've been hearing from him, let's say, a week or so ago, where he was talking in terms of the bombing starting again if Iran didn't agree to a deal.

There was a sense of urgency in what he was saying.
