which I’m sure we did somehow
Trudeau sold him measures that Canada had already voted on. See this post from the end of last year. https://www.canada.ca/en/public-safety-canada/news/2024/12/the-government-of-canadas-border-plan-significant-investments-to-strengthen-border-security-and-our-immigration-system.html
Trudeau “caved” by giving Trump essentially zilch, apparently assuming – perhaps not incorrectly – that Trump would be that easily swindled.
That, now, is indeed a genuine issue. Trump has stated that his end game is annexation, and experience has shown that when he sounds like he’s got a bee in his bonnet about something, however bonkers, he’s actually serious about it. So I’m not seeing him stop the aggression on Canada.
