My impression is that Europe and Canada are mostly at the acceptance phase. But the thing about acceptance is that you still have to deal with the consequences of the event that is causing you grief. That isn't easy when it is the loss of a person/nation on whom/which you have long relied. And when the loss is desertion rather than death, anger is both inevitable and potentially useful.
In Australia, even more than in the US, it's denial all the way. Alliance is "rock solid", "never been stronger". Trump would certainly come to our defence etc. We have an election soon, so no one is going to be the first to point out imperial nudity,
