The US does not enjoy the same circumstances.
It certainly does; its European NATO allies and a few other countries such as Japan are the only allies it could count on; other "allies" have stolen secrets (Israel), funded US enemies (Turkey, Saudi Arabia) and switched sides too often to be reliable (countries like the Phillipines and Vietnam are opportunistic allies at best). Closer to home, there are increasingly demographics whose immediate interests are opposed to American ideals. The majority of any given group would rather have political power for themselves, rather than preserve abstract ideals for everyone. The urbanite cosmopolitans are the enemy of American ideals. So the US is threatened from the outside while being subverted from the inside.
Moving away from the US and seeing the bigger picture, we observe that every country has allies and enemies, every company has competition in the free market, and every individual competes for limited resources. Everything organic is under attack simultaneously.
Well, as far as that goes, things are never so bad, that they can not become shockingly worse.
Exceptions do put the rule to the test, but exceptions are exceptional.
For a person without strong historical knowledge whose entire perception of the humanities is limited to the American experiment, revolution-culture-authority are like colors to a blind person. If history is any indicator of the nature of politics, we know the US and all of the Western Civilization will fall. All these Boomer Sunday Morning Republicans and Democrats are indeed in for a shock when the US collapses.
