“The most successful terrorist campaign in American political history took place after the Civil War.
Ex-Confederate soldiers and ordinary Southerners unwilling to give up on white supremacy formed a series of violent cells aimed at undermining Reconstruction. Their attacks, the most infamous of which were lynchings of recently freed Black people, aimed to disrupt racially egalitarian governments and impose costs on the North for continuing to occupy Southern land.

“If more moderate Republicans are afraid to speak up, extremists will increasingly speak for the party. The more the extremists speak for the party, the more they will push Republicans voters to the far right and embolden violent far-right actors, further intimidating moderate voices from speaking out.
This is one key difference from the political dynamics of the 1970s. Back then, no significant faction of the Democratic Party was aligned with the violent radicals. Today, large sections of the far right see themselves as acting on behalf of or in conjunction with the Trumpist forces in the Republican Party. In footage of Capitol Hill mobbers ransacking the Senate floor, one attacker justifies his actions by saying “[Ted] Cruz would want us to do this.”
“There seem to be enough guns, political support, and rhetorical space to sustain at least some degree of mobilization by violence-curious radicals,” says Paul Staniland, a political scientist at the University of Chicago. “It’s a lot easier to unleash carnage than to pack it back away.””
