So much about the rise of Donald Trump defied reason. But in the spring of 2016, he displayed one habit that I found beyond perplexing: He couldn’t stop praising Vladimir Putin. What made his obsequiousness so galling was that it often came in response to questions that warranted moral disdain: What about the assassination of journalists critical of the Russian government? Are you bothered by the invasion of Crimea? Whereas most of Trump’s policy positions shifted over the course of the campaign, his apologetics for Putin were a rare source of constancy.

As Trump raced to the Republican nomination, I began to search for ulterior explanations for Trump’s adoration of Putin—and the fact that his campaign served as a magnet for so many advisers and consultants with ties to Russian interests. On July 4, 2016, I published a piece in Slate pointing to Putin’s pattern of intervening on behalf of candidates hostile to the Western alliance, and arguing that we were seeing the same sort of interference unfolding in the United States. And I spent much of the next three years trying to understand the nature of that interference.

Two years ago, Desmond Hughes heard so many of his favorite podcasters extolling AirPods, Apple’s tiny, futuristic $170 wireless headphones, that he decided they were worth the splurge. He quickly became a convert.

Hughes is still listening to podcasters talk about their AirPods, but now they’re complaining. The battery can no longer hold a charge, they say, rendering them functionally useless. Apple bloggers agree: “AirPods are starting to show their age for early adopters,” Zac Hall, an editor at 9to5Mac, wrote in a post in January, detailing how he frequently hears a low-battery warning in his AirPods now. Earlier this month, Apple Insider tested a pair of AirPods purchased in 2016 against a pair from 2018, and found that the older pair died after two hours and 16 minutes. “That’s less than half the stated battery life for a new pair,” the writer William Gallagher concluded.

We cannot yet see the report that Special Counsel Robert Mueller submitted to Attorney General William Barr on Friday. But we can see its shadow in the four-page letter Barr sent to the chairs and ranking members of the House and Senate Judiciary Committees on Sunday afternoon. The letter will be touted as vindication by President Donald Trump and his supporters, but will do little to bridge the partisan divide over Mueller’s nearly two-year investigation, and will inspire more vociferous demands to release the entire report.

Barr’s letter thoroughly quelled some of the fondest hopes of the anti-Trump “resistance.” The letter revealed that Mueller closed his investigation without recommending more criminal charges, and that no further indictments are under seal, as some had speculated. That’s a great relief for Trump and his family and associates, but it’s not the end of their federal criminal jeopardy. Barr also pointed out that Mueller “referred several matters to other offices for further action.” For instance, the special counsel sent the investigation of Michael Cohen’s hush-money payments to Stormy Daniels to the U.S. Attorney’s Office for the Southern District of New York, which secured Cohen’s guilty plea for federal campaign-finance violations. That office is still actively investigating the matter—we know this because it carefully redacted the details of the investigation when it released the Cohen search warrants last week. But the special counsel’s investigation was the most prominent legal threat to the president and his family, and its closure without further indictments is a major victory for him.

Good news, America. Russia helped install your president. But although he owes his job in large part to that help, the president did not conspire or collude with his helpers. He was the beneficiary of a foreign intelligence operation, but not an active participant in that operation. He received the stolen goods, but he did not conspire with the thieves in advance.

This is what Donald Trump’s administration and its enablers in Congress and the media are already calling exoneration. But it offers no reassurance to Americans who cherish the independence and integrity of their political process.

The question unanswered by the attorney general’s summary of Special Counsel Robert Mueller’s report is: Why? Russian President Vladimir Putin took an extreme risk by interfering in the 2016 election as he did. Had Hillary Clinton won the presidency—the most likely outcome—Russia would have been exposed to fierce retaliation by a powerful adversary. The prize of a Trump presidency must have glittered alluringly, indeed, to Putin and his associates. Why?

As the nation awaits the Mueller report, a return to first principles is in order. One relevant first principle was dramatically illustrated in the breach during the waning weeks of the 2016 presidential campaign. Then–FBI Director James Comey announced at a press conference that no criminal charges would be brought against Hillary Clinton. Comey didn’t stop there, however. In that press conference, which will continue to live in infamy, Comey sharply criticized the former secretary of state for her ill-considered conduct in housing a server in her private residence, only to receive official and—not infrequently—classified information.

The nation should have risen, as one, in righteous indignation in the aftermath of the Comey press conference. In a single misadventure, Comey both seized power that was not his—the power to seek an indictment, a prerogative that was entrusted to the attorney general—and then violated one of the fundamental principles of public prosecution: Thou shalt not drag a subject or target of the investigation through the mud via public criticism. Prosecutors either seek an indictment, or  remain quiet.

In March 1997, the Watchtower Bible and Tract Society, the nonprofit organization that oversees the Jehovah’s Witnesses, sent a letter to each of its 10,883 U.S. congregations, and to many more congregations worldwide. The organization was concerned about the legal risk posed by possible child molesters within its ranks. The letter laid out instructions on how to deal with a known predator: Write a detailed report answering 12 questions—Was this a onetime occurrence, or did the accused have a history of child molestation? How is the accused viewed within the community? Does anyone else know about the abuse?—and mail it to Watchtower’s headquarters in a special blue envelope. Keep a copy of the report in your congregation’s confidential file, the instructions continued, and do not share it with anyone.

The Iraqi soldier died attempting to pull himself up over the dashboard of his truck. The flames engulfed his vehicle and incinerated his body, turning him to dusty ash and blackened bone. In a photograph taken soon afterward, the soldier’s hand reaches out of the shattered windshield, which frames his face and chest. The colors and textures of his hand and shoulders look like those of the scorched and rusted metal around him. Fire has destroyed most of his features, leaving behind a skeletal face, fixed in a final rictus. He stares without eyes.

On February 28, 1991, Kenneth Jarecke stood in front of the charred man, parked amid the carbonized bodies of his fellow soldiers, and photographed him. At one point, before he died this dramatic mid-retreat death, the soldier had had a name. He’d fought in Saddam Hussein’s army and had a rank and an assignment and a unit. He might have been devoted to the dictator who sent him to occupy Kuwait and fight the Americans. Or he might have been an unlucky young man with no prospects, recruited off the streets of Baghdad.

Between 1965 and 1969, more than a million American soldiers served in combat in Vietnam. One can argue that they should never have been sent there, but no one would argue that, once committed to battle, they should have been given inferior equipment. Yet that is what happened. During those years, in which more than 40,000 American soldiers were killed by hostile fire and more than 250,000 wounded, American troops in Vietnam were equipped with a rifle that their superiors knew would fail when put to the test.

The rifle was known as the M-16; it was a replacement for the M-14, a heavier weapon, which was the previous standard. The M-16, was a brilliant technical success in its early models, but was perverted by bureaucratic pressures into a weapon that betrayed its users in Vietnam. By the middle of 1967, when the M-16 had been in combat for about a year and a half, a sufficient number of soldiers had written to their parents about their unreliable equipment and a sufficient number of parents had sent those letters to their congressmen to attract the attention of the House Armed Services Committee, which formed an investigating subcommittee. The subcommittee, headed by Representative Ichord, a Democrat from Missouri, conducted a lengthy inquiry into the origins of the M-16 problem. Much of the credit for the hearings belongs to the committee’s counsel, Earl J. Morgan. The hearing record, nearly 600 pages long, is a forgotten document, which received modest press attention at the time and calls up only dim recollections now. Yet it is a pure portrayal of the banality of evil.

BEIRUT—If you’re looking to transfer money here, there’s a chance you will be directed to Abu Shawkat. He works out of a small office in a working-class suburb of the Lebanese capital, but won’t give you its exact location. Instead, he’ll direct you to a nearby alleyway, and whether he shows up depends on whether he likes the look of you.

Abu Shawkat—not his real name—is part of the hawala system, which is often used to transfer cash between places where the banking system has broken down or is too expensive for some to access. If he agrees to do business, you’ll set a password and he will take your cash, then provide you with the contact information of a hawala broker in the city where your money is headed. Anyone who offers that specific password to that particular broker will get the funds. Thus, cash can travel across borders without any inquiry into who is sending or receiving it, or its purpose.

Cottage cheese faced a problem: After World War II, batches of the soft, lumpy dairy concoction developed a propensity to take on a rancid odor and a bitter taste. That changed in 1951, when dairy researchers identified the culprits, three bacterial miscreants that produced this “slimy curd defect.” To prevent the condition, researchers advised cheesemakers to keep these bacteria from entering their manufacturing facilities in the first place. Thus ended the scourge.

Despite this and other advances in cottage-cheese production, like texture analyzers, high-powered microscopes, and trained human tasters, cottage cheese has never enjoyed the same popularity as yogurt. That’s because cottage cheese, once revered for its flavor and versatility, has taken a series of gut-punches in the dairy sector: enduring associations with weight loss, inconvenient packaging, and near-total displacement by its cousin, Greek yogurt, to name a few. But stalwart food scientists and artisanal dairy farmers have high hopes for the future of cottage cheese. With yogurt sales on the decline, a golden age of curds might be right around the corner.
