Not only but now the trust is broken
Let's say this was SomewhereElsistan and they elected someone who just cancelled contracts, backed out of treaties, refused to pay balances, fired entire departments and maybe even arrest your international colleague working there and sent them to a foreign concentration camp.
Afterwards they elect Johnny Reasonable who doesn't do this.
Would you go back with any kind of assurance it wouldn't happen again? Nobody stopped the first guy.
The US reputation in international markets is hosed for decades unless some dramatic reversal and patching comes in, by both Congress and the courts or some wild thing where the states override the federal government somehow.
Otherwise the trust is gone for decades, perhaps forever.
