Fair enough, and we got a delay on the tariffs and presumably my prediction of Trumpian apocalypse.
How about a less exciting but barely less alarming scenario?
After a little economic disruption, Trump's minions rig an election and install a puppet government supported by state controlled social media and useful idiots like the Freedom Convoy fools. Canadians are outraged by the obvious fraud, and take to the streets. The government invites the Yanks in to help deal with the antifa terrorist threat and the rest is obvious.
This is how the US has treated every country below the Rio Grande for 200 years. Why would Trump do any differently just because we're Canada?
