leaders do not accept the legitimacy of our current political system.

Henry Kissinger, of all people, provides the best lens for viewing the new administration.  And Krugman summarized it best (in 2003):

"It seems clear to me that one should regard America's right-wing movement--which now in effect controls the administration [...] as a revolutionary power in Kissinger's sense. That is, it is a movement whose leaders do not accept the legitimacy of our current political system."
