So can Canada make a law stating the country to the south shall henceforth be called the Untrustworthy Shithole of America? Will google, apple, etc. show that on the maps for Canadians?

You say that, but a lot of his wealth in other things is from leveraging TSLA. If that drops it might have a cascade effect.

Canada won’t willingly be part of the US. If the US invades Canada, it would be the end of the US.

The US gets boners over their military tech, but they weren’t able to successfully occupy Vietnam, Afghanistan, Iraq, etc. Canada is bigger than those countries, and this would not be an overseas war where they can just go home when they fail. Americans don’t have the willpower to succeed with a long drawn out occupation. They freak the fuck out over a few drones in New Jersey, they obviously wouldn’t be able to handle a war on the North American continent involving drones flying over them carrying explosives and searching for targets. And that’s just the tip of the iceberg of what a US war with Canada would be like.
