There is no unringing this bell. Maybe a sane administration would slow the migration, but the damage is done. America is a capricious partner who can flip the table at any moment.

100%

The reason there is no unringing this bell is not just that we have a capricious, vainglorious president, it's that all of checks and balances that are supposed to restrain the executive have proven worthless so far. Republicans in Congress have completely declared their impotence, having fully relinquished their duties that the Constitution specifically delegates to the legislative branch, like tariff power, war powers, etc.

A terrible potential is that US products may find themselves unable to get footing internationally, due to broken trust and increased competition, so instead they'll try to rely on every-expanding protectionism and corruption to stay dominant in the US market.

Just as we've seen in the car industry we'll wind up less innovative, less productive, and less economical.
