Until a few decades ago, most Democrats did not hate Republicans, and most Republicans did not hate Democrats. Very few Americans thought the policies of the other side were a threat to the country or worried about their child marrying a spouse who belonged to a different political party.

All of that has changed. A 2016 survey found that 60 percent of Democrats and 63 percent of Republicans would now balk at their child’s marrying a supporter of a different political party. In the run-up to the 2020 presidential election, the Pew Research Center reported that roughly nine out of 10 supporters of Joe Biden and of Donald Trump alike were convinced that a victory by their opponent would cause “lasting harm” to the United States.

On March 9, 1862, the Union warship Monitor met its Confederate counterpart, Virginia. After a four-hour exchange of fire, the two fought to a draw. It was the first battle of ironclads. In one day, every wooden ship of the line of every naval power became immediately obsolete.

On December 7, 1941, the Japanese bombed Pearl Harbor. If the battle of the ironclads settled once and for all the wood-versus-iron debate, Japanese carrier-based aircraft settled the battleship-versus-carrier debate by sinking the cream of America’s battleship fleet in a single morning.

On April 14, 2022, the Ukrainians sank the Russian cruiser Moskva with a pair of Neptune anti-ship missiles. And that success posed an urgent question to the world’s major militaries: Has another age of warfare just begun? After 20 years spent fighting the post-9/11 wars, the United States military’s attention is again focused on a peer-level adversary. The Pentagon hasn’t been thinking this way since the Cold War, and it is attempting a profound transformation. Today, fierce debate attends this transformation, and nowhere more acutely than in the Marine Corps.

Carnage in the cryptocurrency market is nothing new. Over the past decade, even as the value of cryptocurrencies like bitcoin and ether has risen sharply, crashes have been a regular feature of the market. (There’s a reason HODL—“Hold on for dear life”—is a mantra among crypto believers.) But even by crypto standards, the destruction of value over the past six months—and in particular, over the past few weeks—has been staggering.

Since November, something like $1.5 trillion in cryptocurrency value has been erased. Bitcoin and Ethereum, the market’s bellwethers, are both down about 60 percent from their peaks. And most strikingly, the so-called stablecoin Terra and its sister token, Luna, which together were valued at about $60 billion six weeks ago, imploded in a matter of days and are now essentially worthless.  

When I train medical students, I emphasize that almost nobody is more acutely aware of time than an obstetrician is. Whenever doctors in my field are briefed about a new patient, the first question we ask is: “How many weeks?” The answer affects everything. A pregnant patient diagnosed with high blood pressure at 12 weeks is usually suffering from chronic hypertension, a condition not immediately dangerous to her. At 37 weeks, a similar blood-pressure reading signals preeclampsia, a direct risk to the patient and her fetus. A patient whose water breaks the week before her due date, at 39 weeks, is probably going to have a healthy baby; someone in the same situation at 20 weeks faces a terrifying ordeal that will probably end in infection and pregnancy loss. The dangers that a patient faces, the treatment options we can consider, the risks she may be willing to take—all of these evolve over the nine months of a pregnancy. The only people who understand this better than obstetricians do are our pregnant patients themselves, who count every passing moment in their bodies.

Yesterday afternoon, I called the UCLA epidemiologist Anne Rimoin to ask about the European outbreak of monkeypox—a rare but potentially severe viral illness with dozens of confirmed or suspected cases in the United Kingdom, Spain, and Portugal. “If we see those clusters, given the amount of travel between the United States and Europe, I wouldn’t be surprised to see cases here,” Rimoin, who studies the disease, told me. Ten minutes later, she stopped mid-sentence to say that a colleague had just texted her a press release: “Massachusetts Public Health Officials Confirm Case of Monkeypox.”

The virus behind monkeypox is a close relative of the one that caused smallpox but is less deadly and less transmissible, causing symptoms that include fever and a rash. Endemic to western and central Africa, it was first discovered in laboratory monkeys in 1958—hence the name—but the wild animals that harbor the virus are probably rodents. The virus occasionally spills over into humans, and such infections have become more common in recent decades. Rarely, monkeypox makes it to other continents, and when it does, outbreaks “are so small, they’re measured in single digits,” Thomas Inglesby, the director of the Johns Hopkins Center for Health Security, told me. The only significant American outbreak occurred in 2003, when a shipment of Ghanaian rodents spread the virus to prairie dogs in Illinois, which were sold as pets and infected up to 47 people, none fatally. Just last year, two travelers independently carried the virus to the U.S. from Nigeria but infected no one else.
