It's much easier to destroy than build, and some things once destroyed can't be rebuilt.

Trump's inconsistent tariff and policy flip flopping means no one trusts the US to behave rationally and predictably.

The fact that the US population elected him a second time means that the US as a whole can't be trusted to behave like rational adults.

Decades or centuries of reputation has been thrown away. That can't be changed just by a new face saying "sorry we want to take it back".
