Healthy skepticism is good. It saves us from being too naive or too cynical. But it is impossible to preserve democracy when the well of trust runs completely dry. The freedoms enshrined in the Bill of Rights and the checks and balances in our Constitution were designed to prevent the self-inflicted wounds we face today. But as our long history reveals, those written words must be applied by people charged with giving life to them in each new era. That’s how African Americans moved from being slaves to being equal under the law and how they set off on the long journey to be equal in fact, a journey we know is not over. The same story can be told of women’s rights, workers’ rights, immigrants’ rights, the rights of the disabled, the struggle to define and protect religious liberty, and to guarantee equality to people without regard to their sexual orientation or gender identity. These have been hard-fought battles, waged on uncertain, shifting terrain. Each advance has sparked a strong reaction from those whose interests and beliefs are threatened. Today the changes are happening so fast, in an environment so covered in a blizzard of information and misinformation, that our very identities are being challenged. What does it mean to be an American today? It’s a question that will answer itself if we get back to what’s brought us this far: widening the circle of opportunity, deepening the meaning of freedom, and strengthening bonds of community. Shrinking the definition of them and expanding the definition of us.

My chest tightens at the thought of what all this could mean to Lilly. But I have no choice. I made a vow to defend this country, and I’m the only person who can do this.

And it’s been a long time since she’s “felt like herself,” as Americans would say. At most, she has an occasional window of relaxation. But the longer she stays in this line of work and the more times she reinvents herself — replacing one facade with another, sometimes lingering in shadow, sometimes hiding in plain sight — the less she remembers her true self or even the concept of having her own identity. That will change soon, a vow she has made to herself.

They climb the stairs with the proper tactical approach, securing each staircase with a single soldier — a scout — before the rest of the team proceeds upward. There are blind spots everywhere. Ambush opportunities on each level. Their contact at the front desk has given an all-clear on the stairwells, but he is only as competent as the cameras he monitors.

Headed for the exit,” she hears through the earbud. “Teams 1 and 2, go,” she says. “Team 3, hold ready.” “Team 1, that’s a go,” comes the response. “Team 2, that’s a go.” “Team 3 holding ready.

She hears the men near the front of the open-air space, where they are tending to the wounded, shouting at one another, blaming one another in a language she doesn’t understand. But she understands panic in any tongue. She lets her heels click loudly enough for them to hear her coming. She didn’t want to preannounce her arrival lest there be an ambush awaiting her — old habits die hard — but likewise she finds no advantage in startling a group of heavily armed, violent men.

Our democracy cannot survive its current downward drift into tribalism, extremism, and seething resentment. Today it’s “us versus them” in America. Politics is little more than blood sport. As a result, our willingness to believe the worst about everyone outside our own bubble is growing, and our ability to solve problems and seize opportunities is shrinking.

Chancellor Juergen Richter sits with his one aide, a fair-haired young man named Dieter Kohl, the head of Germany’s BND, its international intelligence service. Prime Minister Noya Baram brought her chief of staff, a stout, formal, older man who once served as a general in the Israeli army.

Remembering the words of Ranko, her first teacher, the toothpick jutting out from the side of his mouth, his fiery red, stalklike hair — a scarecrow whose hair caught fire, as he once described himself.

"Think of how much more rewarding it would be if we all came to work every day asking, "Who can we help today and how can we do it?" instead of "Who can I hurt and how much coverage can I get for it?

Good morning, Mr. President,” says Jenny Brickman, my deputy chief of staff and senior political adviser. She ran my campaigns for governor and worked under Carolyn on my presidential run. She is petite in every way, with a mess of bleached blond hair and a mouth like a truck driver. She is my smiling knife. She will go to war for me, when I let her. She would not merely dissect my opponents. If I didn’t rein her in, she would slice them open from chin to navel. She would rip them to pieces with all the restraint of a pit bull and slightly less charm.

Jiang Lijun is not a vice president for the China State Construction Engineering Corporation but a senior officer with the Ministry of State Security. What the hell are the Americans up to?
