When 9/11’s Unity Fades to Discord

In the quarter-century since that fateful morning, Americans have lost sight of what it means to be a nation bound by shared purpose rather than divided by entrenched convictions. The memories of 9/11 have been reduced to a familiar narrative: the attacks themselves, the heroes who risked everything in response, and the unity that briefly followed. Fewer recall the weeks and months that followed, when Americans from all walks of life came together to volunteer, enlist, or simply welcome strangers into their homes.

The erosion of collective memory is not coincidental. As we’ve allowed our differences to harden into absolutes, we’ve forgotten the messy, often contentious process of building the 9/11 Memorial & Museum itself. The fights over how to arrange the names of the dead, how and whether to represent the hijackers, and what to include about America’s response were real conflicts waged by people with deeply held convictions. Yet in the end, we still built on sacred ground.

The Terms of the Deal

A democracy depends on certain distinctions: the rule of law, free expression, and equal citizenship are not partisan preferences but the fundamental terms of our social contract. Protecting someone’s right to reject the American experiment is different from treating that rejection as simply another interpretation of it. A pluralistic society can tolerate almost limitless disagreement precisely because there are some principles it cannot and should not surrender.

The 9/11 Memorial & Museum’s experience teaches us that accepting our differences is harder than making them disappear. We could tell the truth about American failures without concluding that America itself was a failure. We could explain why the terrorists hated this country without adopting their indictment of it.

The Erosion of Consensus

Twenty-five years later, we’re alarmed not by the solidarity we’ve lost but by the erosion of consensus about the terms under which we disagree. A recent survey found that only 66% of Americans now say democratically elected government is “extremely” or “very important” to the nation’s identity, down from 80% in 2021. Another recent survey revealed that roughly one in five Americans endorse harassment, doxxing, or even violence against their political adversaries.

Moral Absolutism

The figures belie a disturbing trend in our political discourse: moral absolutism. A healthy democracy makes space for fierce dissent, but the danger comes when political clashes become crusades and the self-declared righteousness of the cause becomes license to abandon democratic restraints. We’ve forgotten that pluralism doesn’t require agreement; it requires accepting that sometimes you will lose the argument but staying at the table anyway.

What’s at Stake

The America attacked that morning was never defined by consensus. It was defined by a shared conviction that our freedoms belong as fully to people we bitterly oppose as to people we love; that our democracy is worth defending not because it settles our differences, but because it gives us a way to live with them. The victims of 9/11 “represented the American experiment itself,” writes Joe Daniels, founding president and CEO of the 9/11 Memorial & Museum.

The Way Forward

The 25th anniversary demands more from us. It’s not just a chance to remember but also an opportunity to recommit ourselves to the principles that have always defined America: freedom, equality, and democracy. We must learn to disagree without becoming enemies; to tolerate differences without surrendering our shared values. Only then can we truly honor the memory of 9/11.

As we stand on the precipice of a new era, one thing is clear: we’ve forgotten what it means to be a nation bound by shared purpose rather than divided by entrenched convictions. The question now is whether we’ll rediscover that unity or succumb to the erosion of consensus.
