Agreeing with you. Trump's attitude on the global stage has been to disrespect, insult and threaten every ally. Come at everyone with a "we're better than you" attitude and show that he can't be trusted. The only rational response is to take steps to be more independent and find ways to work around the US. What's the alternative? Give in to a narcissistic bully who won't keep his word and will inevitably come asking for more later?

In the medium to long term, Trump is very old, his approval ratings are in the toilet. I hope that the democrats do well in the midterms and put up a viable candidate to beat him next election (if he's still alive). I also hope that the republicans manage to put up someone smarter and less morally reprehensible next time. Because I mean, this guy doesn't actually represent any kind of conservative ideal in any way. The only people he appeals to are those one or two standard deviations on the left of the bell curve.

If the next US president is halfway sane, Canada and the US will likely begin to repair trade relationships, but I think that Canada and the rest of the world will be a bit more careful next time. The US may never regain the international standing they enjoyed before. Trump has made China look like the more stable and rational trading partner, and accelerated the decline of the US.
