Can the US and Iran Conclude a Lasting Deal to End the War?

As the clock runs down on a two-week ceasefire agreed between the US and Iran, the key question is whether they can reach an accord to end a war that has killed thousands of people and sparked a global energy crunch.

While talks in Pakistan concluded without a deal, the two sides are considering extending their truce by another fortnight to allow more time to negotiate a peace agreement, according to a person familiar with the matter.
