Yes, I think the case can be made that an unstable USA is Canada’s biggest threat. I think the next 2-4 years will be an indicator of where things are going.Wouldn't wish it on anyone..
They must have a lot more confidence in America than some Americans I talk to. There is a real possibility that the US becomes effectively ungovernable mess or otherwise preoccupied with its own internal issues. There are plenty of scenarios where even if they are willing, that they aren't able. Even a global power needs to focus its resources elsewhere at times, and sometimes that can even lead to trying to usurp/redirect other nations resources and capabilities, as an ally against that nations own interests.
There are also a lot of scenarios at play beyond traditional ideas of sovereignty and SLOC. China's play is global, and focuses on weak targets. The world is no longer a benign environment and is likely heading towards a less stable future. Even if China(+Russia) was out of the picture, the magic crystal 8 ball isn't exactly predicting easy times ahead.
