Yes, USA is not. But not because of just Trump. The process started a while ago, when USA elites decided that they’re “exceptional”, and started to promote so called “rules based order”, with the only rule that reads like “USA may do whatever they want to do, and you have to obey our orders, or you’ll be punished”.

Diplomacy is dead in USA. These days nobody sane in the world believes anything coming out of White House, not even a paper, and Trump is just a current facade for the same elites that nobody trusts.
