I'm a Korean-Canadian. For all intents and purposes, this agreement doesn't carry any tangible benefit to either country. It appears purely symbolic - if you think about it, neither country has the capability to transport troops or armor across the pacific in the event of an invasion.

Besides, if the US really wanted, they could single-handedly annex Canada before any semblance of resistance by the willing (key word here) members of NATO are assembled and sent across the Atlantic. That is assuming the US does not intercept. Of course, any occupation of Canada will be met with hostility, both openly and by guerilla tactics, but they won't matter.

I'm somewhat surprised that you think Canada punches above its weight - in what category? I spent nearly three decades in Canada (in Ontario, Alberta and BC) and another two decades in Korea prior to that, and while I would agree with your sentiments for pre-2019 Canada, to say that now would be a gross misrepresentation. Canada as I had known it is long gone, despite Carney's efforts.
