The Case of Kristie Metcalfe

A continuing military investigation has determined that the United States is responsible for a strike that hit an elementary school in Iran, according to U.S. officials and others familiar with the preliminary findings. Iranian officials have said the death toll was at least 175 people, most of them children. Malachy Browne and Julian E. Barnes, who have been covering the strike, discuss what probably led to one of the most devastating military errors in decades.

As Iran has tightened its chokehold on one of the world’s most vital shipping routes and the Trump administration sent mixed signals about how long the war would last, oil prices have swung wildly. Rebecca F. Elliott, who covers energy for The New York Times, explains just how much the world depends on that route — the Strait of Hormuz — and how quickly shutting it down can throw global energy markets into chaos.

What began as a relentless U.S.-Israeli military assault on Iran has turned into a wider crisis as the disruption of the world’s oil markets spreads beyond the Middle East. Eric Schmitt, a national security correspondent for The New York Times, discusses what we know about the players involved in the fighting.

In recent weeks, the Defense Department has tussled with Anthropic over how its artificial intelligence could be used on classified systems. That fight became bitter and negotiations fell apart. And war in the Middle East has made it increasingly clear how much the U.S. military has been relying on A.I. Sheera Frenkel, who covers technology for The New York Times, explains the standoff and what it reveals about the future of warfare.

Today on “The Sunday Daily,” The Times’s chief movie critic, Manohla Dargis, talks with the “Daily” host Michael Barbaro about this year’s batch of Oscar nominees, which — according to her — are uncommonly good. They discuss the performances that Dargis believes deserve to win, the dark horses that might pull off upsets, and the ambitious films that give her hope for Hollywood’s future.
