Frankly I think the current Canadian policy should be "no direct neighbours"¹. Pre-emptively cutting ties with USA, instead of waiting for it to happen; at least Canada would the one deciding when and how to do so.

So. USA wants to steal half a bridge? Say “fuck off”, insist on it, escalate issues a bit (remember TACO: Trump Always Chickens Out), but stop building further bridges to USA. Why would you build bridges to what you should be treating as a desert¹?

Another example: USA will most likely revoke the USMCA. Before this even happens, Canada and Mexico should be signing bilateral agreements to replace it.

Also: give up rekindling ties after Trump leaves/dies². That brainless muppet is a symptom of USA going downhill, but the actual cause are the people who put him on power. (Spoilers: not the United-Statian population. Follow the money.) Without Trump they’d easily put someone as bad as him in place.

Trump continued: “The first thing China will do is terminate ALL Ice Hockey being played in Canada, and permanently eliminate The Stanley Cup.”

…what.

1. By “desert” I mean on economic grounds. On military grounds it’s probably better if Canada accurately treats the situation by what it is, it borders a rogue state.
2. I wouldn’t be surprised if Trump changed the rules in USA, to allow himself to become president for life, Maduro style. Also, it would be damn hilarious if someone did with Trump what he did with Maduro.
