As the anniversary of the insurrection at the U.S. Capitol approaches, three retired U.S. generals have warned that another insurrection could occur after the 2024 presidential election and that the military could instigate it.

The generals – Paul Eaton, Antonio Taguba and Steven Anderson – made their case in a recent Washington Post op-ed. "In short: We are chilled to our bones at the thought of a coup succeeding next time," they wrote.

"There are lots of fully armed people wondering what's happening to this country," he says. "Are we going to let Biden keep destroying it? Or do we need to get rid of him? We're only going to take so much before we fight back." The 2024 election, he adds, may well be the trigger.

Nieznany is no loner. His political comments on the social-media site Quora received 44,000 views in the first two weeks of November and more than 4 million overall. He is one of many rank-and-file Republicans who own guns and in recent months have talked openly of the need to take down—by force if necessary—a federal government they see as illegitimate, overreaching and corrosive to American freedom.

The phenomenon goes well beyond the growth of militias, which have been a feature of American life at least since the Ku Klux Klan rose to power after the Civil War. Groups like the Proud Boys and the Oath Keepers, which took part in the January 6th riot at the Capitol and may have played organizational roles, have grown in membership. Law enforcement has long tracked and often infiltrated these groups. What Nieznany represents is something else entirely: a much larger and more diffuse movement of more-or-less ordinary people, stoked by misinformation, knitted together by social media and well-armed. In 2020, 17 million Americans bought 40 million guns and in 2021 were on track to add another 20 million. If historical trends hold, the buyers will be overwhelmingly white, Republican and southern or rural.
