Fascism doesn’t actually last that long. At some point, policies have to have some kind of attachment to reality, and fascists are incapable of grappling with reality.

Franco stuck around for quite awhile, but yeah its track record is usually short.

putin and kim have been going for quite some time.

Those are well crafted, defensive dictatorships at this point that have had decades and decades to sow the seeds of complacency and authoritarian control of their population. In one of those examples, the people of NK worship Kim and his father and grandfather as literal gods. So Americans aren’t quite there yet.

Not saying they’re super far off, but still a bit to travel before you get to centuries of repressed soviet/russian control and literal god-king dictators with an iron first around their populace.
