The former president has avoided playing favorites in the 2020 Democratic race. Michaela Rehle/Reuters | | Five Democratic candidates have used the former president’s words or likeness in campaign ads, and just about everybody has invoked him leading up to the South Carolina primary on Saturday and Super Tuesday voting next week. | | Several allies say that while Mr. Obama has opinions about the race, he sees his role as unifying the party once a nominee is selected. | | Related: In South Carolina, where black Democrats cast more than 60 percent of the primary vote, churches are tried-and-true campaigning stops. But some black voters have grown impatient with seeing politicians on Sunday and feeling forgotten on Monday. | | At least 33 Turkish soldiers were killed and more than 30 wounded in an airstrike in northwest Syria on Thursday. Turkey blamed Syrian government forces, but the airspace is controlled by Russia, and Russian jets have conducted most of the strikes in recent weeks. | | Protesters converged on the Russian Consulate in Istanbul early today, chanting, “Murderer Russia! Murderer Putin!” | | Background: Our Istanbul bureau chief, Carlotta Gall, writes: “Turkey has long supported opposition forces in Syria’s nine-year civil war against the government of President Bashar al-Assad. Mr. Assad, backed by Russia and Iran, has largely defeated the uprising, at a cost of hundreds of thousands of lives and the creation of millions of refugees.” | | News analysis: President Trump has sought to avoid confronting the leaders of Russia and Turkey. But the airstrike on Thursday may force him to pick a side. | | Jens Mortensen for The New York Times | | Emily Flitter, a business reporter for The Times, was devoted to an eco-friendly brand of toilet paper. When it disappeared, she had to know why. | | She writes: “In my search for answers, I learned about waste and consumer choice; about environmentalism; about the different ways Americans and Europeans wipe their tuchuses. And I learned that what had seemed obvious to me was not conclusively true.” | | PAID POST: A Message From XBrand | Renewable Energy in Today's Age | Look around you...All of the things that you love about this planet can be used to power it. the sun, rain, wind, tides and waves.

Melina Delkic of the Briefings team talked to our senior Afghanistan correspondent, Mujib Mashal, about what peace might look like. | | Your latest article focuses on young soldiers whose lives have been shaped by war and who now get to imagine peace. What did they tell you? | | The question I posed was: Listen, peace means that, eventually, tens of thousands of Taliban fighters that are out there either lay down their arms or integrate into the United Afghan security force. That means you, a 21-year-old who has fought as a child soldier since you were 14 against these Taliban, will be sitting with them around the same dinner table. Are you ready for that? | | They were like, “I hate their guts.” And a lot of them hadn’t digested that question. | | The members of Lt. Col. Musa-Kalim Rodwal's police unit are finally able to fetch water without fearing Taliban snipers will take them out. Kiana Hayeri for The New York Times | | What’s the big question looming about the way forward? | | This war started largely as an American war. But in its second decade, this increasingly became a very localized Afghan-on-Afghan war — this became relatives on two different sides, on the government side and on the insurgent side. | | The big question is, What is the process for undoing this hatred, this animosity that’s been so localized? That’s going to require a lot of hand-holding and attention and time. Does the U.S. have the patience to stick around for that to complete in a proper way? | | You were born in Kabul and have covered this war for the past seven years. As a reporter, what is it like to imagine peace? | | The whole past year of focusing on the potential for a resolution to the conflict has been refreshing in a lot of ways. The past seven years, a good chunk of it, I was reporting on a story that was a bleeding stalemate. | | Every day, every week, we were reporting on death after death after death. It was frustratingly, heartbreakingly hopeless. It’s almost felt as though I’ve been an obituary writer; we were finding human stories to remind people that, hey, these 50 dead all had hopes and dreams and lives. | | The past year, there was this opening that finally this conversation could turn. As a reporter, part of me almost feels as if it’s returning to a normal reporting job: politics, diplomacy, deals. The past week gave me an idea of what reporting on Afghanistan would be like if it were a more normal place. | | A correction: Wednesday’s briefing misstated Harvey Weinstein’s inmate number.
