Please tell that to European countries buying F35.
Hopefully, this insanity ends in four years.
A reputation of reliability explicitly means not pulling tricks like these. If you do, it means you're unreliable.
And NATO-countries are very much considering the US an unreliable partner. Also it's interesting that you wrote "partner": 2 months ago people would have said "allies", now it's "unreliable partner".
Hell, Korea almost turned into a dictatorship in the last few months and Yoon still has a lot of support even after being found out and removed. Democracies are fragile and the only way I can see them surviving is if power isn't concentrated.
I don't know inside the US, but outside I'm pretty sure that it won't come back to the way things were 2 months ago. Not only Trump has broken stuff, but the US people too! The US people is still supporting Trump. The message sent to other countries is not "that was a mistake, we elected a crazy arse". The message is "we support that guy that threatens to invade our allies; if we had to vote right now we would elect him again".
however they saw what happened (including the events of Jan 6th), and they did it again
so it's not a one-off, it's a pattern
the rest of the west would be foolish to treat this as anything other than a permanent new direction
Can you show me leaders of countries in the rest of the world who have been making nazi salutes while staying really popular, too?
Do you know that far right leaders from other countries have refused to appear next to far right leaders from the US after nazi salutes, because it seemed a bit too extreme to them?
