If that were the case then no dictatorship anywhere would ever get embedded. Contrary to the widespread cultural belief in the US, people everywhere like freedom and integrity in public life; they're just not as individualistic about it, because most countries were settled many centuries earlier, and there is not an ethos of pioneering based on the idea of infinite free land and resources.

The problem with dictatorship is that of first-mover advantage; once a dictatorship becomes embedded it's hard to dislodge. There's de facto control of the legal, electoral, and cultural infrastructure which the regime can use to (ostensibly) re-legitimize itself every few years, while in the meantime suppressing dissent through violence and fear. That would be very much in line with the stated goals and actions of the administration so far. And I don't mean this hyperbolically; Trump stated that he would be a dictator on day one, and while his supporters brushed this off as a joke his autocratic behavior since entering office is wholly consistent with that.

Barring abrupt reversals in the next month or two, I think this is going to become a long-term situation, and there is simply no way the US can go back to two party pendulum politics after this. It would be like getting out of hospital after a stroke or a heart attack and heading straight back to an all-you-can-eat steakhouse.
