I sincerely hope you are correct, but it's difficult to know the following:

1. just how many citizens were sympathetic to the rioters as they saw those events on unfolding on their screens

2. how their collective behavior will change as a result

I wouldn't say that "existential threat" is hyperbole, I'd say that its accuracy depends on the answer to the above questions.

I wasn't worried about the immediate collapse of the America at the hands of the Capitol mob.
