The entire campaign/programming around "protecting our democracy" was the precursor psychological operation so the population goes along with single party rule.
NBC News was running this last year (more priming): https://ww3.bongino.com/wp-content/uploads/2021/08/dhsadviso.... It's all clever wordplay designed to manipulate the public into thinking people who disagree politically are terrorists (absent any actual proof that they have intent/motive/etc to commit acts of terror). It's the same logic that's held people from January 6th in solitary confinement without charges of insurrection (despite the media parroting/programming that it was an insurrection).
This new unit is just a way to flush out the straggler dissidents who will get in the way.
One person’s terrorist is another’s freedom fighter, especially domestically. Nelson Mandela is a fine example of one of the greatest humans in history who was defined by the South African government as a domestic terrorist during apartheid.
