The problem was never Trump.
Trump is the readable version of a text that was always there, written in language most people couldn't access.
The problem is the system that produced him, that uses him, that will survive him, and that will next time find someone equally willing to do what he does but competent enough to do it quietly.
The competent version is more dangerous.
The competent version rebuilds the language. Restores the branding. Hires the speechwriters who know how to say "shared values" and "rules-based order" while executing identical policy.
And the people who spent four years appalled by Trump's vulgarity will feel the relief of good grammar and take it for moral improvement.
The empire doesn't need Trump specifically.
It needed what he provided: a stress test. A period of operation without the usual ideological cover, to see what held and what didn't.
What held: the sanctions. The bases. The vetoes. The dollar. The weapons sales. The regime change operations.
What didn't hold: the manners.
And when someone comes along who can restore the manners while keeping everything else, and they will, they always do, the people who thought the problem was the manners will call it a recovery.
The rest of us will know what it actually is.
