From the editorial:

One year after the smoke and broken glass, the mock gallows and the very real bloodshed of that awful day, it is tempting to look back and imagine that we can, in fact, simply look back. To imagine that what happened on Jan. 6, 2021 — a deadly riot at the seat of American government, incited by a defeated president amid a last-ditch effort to thwart the transfer of power to his successor — was horrifying but that it is in the past and that we as a nation have moved on.

This is an understandable impulse. After four years of chaos, cruelty and incompetence, culminating in a pandemic and the once-unthinkable trauma of Jan. 6, most Americans were desperate for some peace and quiet.

On the surface, we have achieved that. Our political life seems more or less normal these days, as the president pardons turkeys and Congress quarrels over spending bills. But peel back a layer, and things are far from normal. Jan. 6 is not in the past; it is every day.

It is regular citizens who threaten election officials and other public servants, who ask, “When can we use the guns?” and who vow to murder politicians who dare to vote their conscience. It is Republican lawmakers scrambling to make it harder for people to vote and easier to subvert their will if they do. It is Donald Trump who continues to stoke the flames of conflict with his rampant lies and limitless resentments and whose twisted version of reality still dominates one of the nation’s two major political parties.

In short, the Republic faces an existential threat from a movement that is openly contemptuous of democracy and has shown that it is willing to use violence to achieve its ends. No self-governing society can survive such a threat by denying that it exists. Rather, survival depends on looking back and forward at the same time.

Truly grappling with the threat ahead means taking full account of the terror of that day a year ago. Thanks largely to the dogged work of a bipartisan committee in the House of Representatives, this reckoning is underway. We know now that the violence and mayhem broadcast live around the world was only the most visible and visceral part of the effort to overturn the election. The effort extended all the way into the Oval Office, where Mr. Trump and his allies plotted a constitutional self-coup….
