We have to discount very heavily what the president says based on past experience. We've been close to a deal for weeks.

Both sides want out of the war, which is why we have a ceasefire. The nuclear part is complicated and has taken months or years to negotiate historically.

Both sides will be sensitive - Trump to rising oil prices, the Iranians to restrictions on imports and exports.

So long as both sides want out and see a way out, they will find ways to keep things from blowing up.
