It will cause far, far greater economic damage to the US and globally, to the American consumers, American voters.

But that also relies on the idea that the Iranians are negotiating in part in good faith,

and on the basis of a clear-eyed view of their national interest and not out of revenge or vindictiveness or ideology and theocracy and that they're a suitably unitary actor to implement what the negotiators agree with.

And all of those things are open to question.

So for all of those reasons, I think that Trump is only getting himself in deeper and deeper trouble here.

So you're right, he painted himself into a corner

But like that doesn't mean digging yourself into a hole after you're painted in the corner.

Right.

I mean, it's a lot.

At some point, logic tells you, OK, you're going to get some paint on your shoes.

Walk out of there.

Walk out of there.

They can't.

The question is, what are the implications of that?

Now, I think that were the Americans to do that, the Iranians, if they were to charge prohibitive tolls and no one signs up to it, only very small numbers of countries, then oil prices are still high.

The Americans could easily turn back to a blockade at any moment.

So that option remains there for the United States.

Number one, turn the money off for the Iranians.

Number two, you've got the option of what Trump intimated by saying it's the problem of the other countries is they end up doing deals with the Iranians.

And you can call it a toll or you can call it reconstruction money.
