OK, so apparently the claim that "no one will ever trust the US or their commitments again" means that businesses and governments will still enter into all manner of trades and alliances and business arrangements with the US, but in their heart of hearts, they won't actually trust the US?
Yes, but it will be much more expensive and inefficient compared to the trades and alliances with nations that are trusted. Basically the US is a failed state. Functioning nations can make agreements that survive leadership changes. The US is not one of those.
Think of it this way:
You loan a friend $5k. They promise to pay it back. They don't.
You may still hang out! But you may never loan them money again unless they give meaningful evidence they've changed.
The US probably has one concrete chance left to prosecute, convict, and jail these folks to rebuild trust. My vibe from the Democrats is that they'll whiff that opportunity.
