>Talk to any Canadian and tell me that trust in the US as an ally hasn't been irreparably damaged.
Firstly, I have no sympathy here. If you trust any foreign government that's not accountable to you to begin with, that's on you.
The upshot is that this serves as a good lesson and wake-up call for Canadians and for us in EU as well that we need to start pulling our weight in the world and looking out for our own interests instead of letting ourselves at the mercy of foreign powers.
People need to learn lessons the hard way on their own skin if they're too stupid to learn from past history, like how Czechoslovakia was fucked over by its allies in WW2 and gave to Hitler on a platter. Don't rely on supposed allies to fight your battles, look out for yourself. That's why I'm a big fan of the Swiss's neutrality system and France's post-WW2 nuclear deterrent program. A strong military is better than stronger allies that can change their mind.
And secondly, nothing is ever irreparably damaged. 80 years ago Japan and US were at war and for over 50 years they've been strong allies. Canada also invaded the US in 1814 and burned down the White House and yet they've been each other closest allies after that. Similarly, in 20 years Russia could be the west's best friend. So relationships between countries change all the time based on how the wind blows. Nothing ever lasts forever, only gullible fools with no understanding of history try to hang onto such idealistic beliefs.
