When a new disease emerges, health organizations turn to a seemingly simple number to gauge whether the outbreak will spread. It’s called the basic reproduction number—R0, pronounced R-nought—and though useful for decision makers, it’s a nightmare for public communication. In brief, R0 is the average number of people who will catch the disease from a single infected person, in a population that’s never seen the disease before. If R0 is 3, then on average every case will create three new cases. But even though it seems incredibly straightforward, it’s hard to calculate and tricky to interpret.

R0 is important because if it’s greater than 1, the infection will probably keep spreading, and if it’s less than 1, the outbreak will likely peter out. So it offers vital information to organizations and nations as they consider how to respond to an outbreak—such as the one the world is currently experiencing.

What happened to us? The question haunts us in the Arab and Muslim world. We repeat it like a mantra. You will hear it from Iran to Syria, from Saudi Arabia to Pakistan, and in my own country, Lebanon. For us, the past is a different country, one not mired in the horrors of sectarian killings. It is a more vibrant place, without the crushing intolerance of religious zealots and seemingly endless, amorphous wars.

Though the past had coups and wars too, they were contained in time and space, and the future still held much promise. What happened to us? The question may not occur to those too young to remember a different world, whose parents did not tell them of a youth spent reciting poetry in Peshawar, debating Marxism in the bars of Beirut, or riding bicycles on the banks of the Tigris in Baghdad. The question may surprise those in the West who assume that the extremism and bloodletting of today have always been the norm.

John Bolton, Donald Trump’s former national security adviser, announced the title of his forthcoming memoir last night: The Room Where It Happened, a reference to the Oval Office, the scene of some of the misdeeds he is likely to attribute to the president. (I had hoped for something jauntier, perhaps ’Stached in the Cabinet.) Accompanying that announcement was a story in The New York Times teasing readers with revelations. The most significant is that Trump allegedly conditioned his release of Ukrainian military aid not only on that country’s announcement of an investigation into Hunter and Joe Biden, but also on its release of evidence of the Biden family’s involvement in Robert Mueller’s probe. In fact, there is no such evidence, and the only people who believe that there is such evidence are wing-nut conspiracy theorists and, it seems, the president of the United States.

Perhaps nothing can persuade Republican senators to convict President Donald Trump, but on Friday, as Representative Zoe Lofgren deftly explained why Trump’s blanket defiance of every House subpoena and request for witnesses was an impeachable obstruction of Congress, the mood in the room noticeably shifted. I had the good fortune to be sitting in the Senate gallery to witness this myself. Republican senators whose attention had wandered refocused one by one until—unusually for this trial—the entire Senate was listening intently to an argument and seemed to be considering it seriously.

The reason for the sudden attentiveness is not far to seek. Representative Lofgren was telling senators of both parties that Trump’s response to the House investigations that led to his impeachment was not merely a middle finger raised to Democrats, but an affront to Congress as a whole. She made clear that, left unrebuked, Trump’s defiance will gut the constitutional authority of both House and Senate not merely to check the personal excesses of any given president, but to oversee the entire executive branch. In short, Lofgren was forcefully reminding Republican senators that Trump is a threat to their own legitimate constitutional power.

On a sweltering July day, I follow Annise Dobson down an overgrown path into the heart of Seton Falls Park. It’s a splotch of unruly forest, surrounded by the clamoring streets and cramped rowhouses of the Bronx. Broken glass, food wrappers, and condoms litter the ground. But Dobson, bounding ahead in khaki hiking pants with her blond ponytail swinging, appears unfazed. As I quickly learn, neither trash nor oppressive humidity nor ecological catastrophe can dampen her ample enthusiasm.

At the bottom of the hill, Dobson veers off the trail and stops in a shady clearing. This seems like a promising spot. She kicks away the dead oak leaves and tosses a square frame made of PVC pipe onto the damp earth. Then she unscrews a milk jug. It holds a pale yellow slurry of mustard powder and water that’s completely benign—unless you’re a worm.
