Well it’s hard to know for sure when trying to figure out the motivation of a crazy person, but it’s probably a combo of wanting to change things on maps, thinking tariffs are a good replacement for having any kind of taxes on the wealthy, wanting Canadian resources for free, not understanding what a trade deficit is, and of course being obsessed with money. Also he probably has a grudge against Canada because Trudeau made fun of him and he’s a small and petty man that’s been given power.

There’s also wanting to emulate his buddies Putin and Xi.
