Letting a few cold feet throw away your relationship with the US is absolutely just as stupid as Trump throwing away the US's relationship with Europe/whoever.

No the US clearly believes they would be better off not part of the rest of the world, the best thing we can do is not to drown in that tantrum, and provide the economic embargo they clearly think will bring them prosperity.

I think it is very clear from the way all US allies have reacted to various provocations that we are taking a long term view. That is the reason we are still spying on our domestic populations for the US despite our reservations about the current executive and their actions.

Less so if the US is going to try to request current (prior?) allies to assist in a war against Iran which has already been declared 'won' and was recommended against by pretty much everyone outside of current participants.

I think you can justify this logic only in the case you sincerely believe that the current admin is a fluke and things will return to roughly the previous status quo on the order of a few years. And that isn't unreasonable to think, but you might also want to have a backup plan.
