What makes you say "certainly," especially in the hypothetical scenario where the US is unstable? Canada has a relatively much shorter history as an independent nation. Canada heavily benefits from its southern neighbor, and has a host of domestic economic issues (low wages, high housing prices; whatever the farmers are on about) that could cause instability as well. I think Canada is reasonably stable, I just quibble with "certainly" and "more" politically stable as compared with the US.
Your "long history as a nation" mostly means you have a flawed constitution, no counter powers, a broken political system and absolutely _zero_ attempts to fix it.
There's a reason proper countries have had 5+ constitutions and keep changing them.
Canada will not invade allies and will adhere to the rule of law. Their forward looking economics are more favorable as they strengthen ties with China and Europe. By decoupling from the US, their economic risk declines, and their sovereign debt risk is downstream of that.
You are arguing as if nothing material in the US has changed while at the same time arguing “be more polite towards my ignorance|avoidance of the situation.” It comes across as arguing in bad faith.
The US can no longer be trusted based on the actions of this administration. Other countries are pragmatically and reasonably adjusting accordingly, very publicly. There are other options besides the US from an economic, trade, investment, and defense ally perspective. These are facts. Whether you believe them is a choice.
No I just think this is so obvious by reading literally any news website for 5 minutes that I can only conclude that someone saying it's "hypothetical" is either acting maliciously or they are actually ignorant of what's going on.
Canada needs to pursue further armament (Carney is pursuing a doubling of its defense budget) and training in asymmetrical warfare.
