Entertainment for his cultists. They like seeing troops on the border. More importantly, they're tearing down the global economy on purpose so they can remake it as they please. If Trump gets his demands met, he knows he can go farther next time. If not, things collapse and his accelerationist billionaire buddies are happy.
It shows them that he's a strong leader who can get other world leaders to do what he wants. He made a threat, and Canada reacted by doing something he demanded. It's incredibly stupid, and will be completely ineffective, but the show of strength is the important part.
I browse /r/conservative occasionally to get a laugh. The entire subreddit is full of "winning posts".
Canada called his bluff, said they'd tariff the US as well...
He gets on a call... Canada says they're going to do something they were already going to do, and all he gets is someone getting the title: "Fentanyl Czar", apparently... and classifying cartels as terrorists.
So much "winning" lmfao. These people are delusional.
Kid A: You need to help me out.
Kid B: I'll help you out, np.
Kid A: If you don't help me out, I'm not letting you play with my toys!
Kid B: Okay, then you can't play with mine
Kid A: You're being so mean, I just need you to help me out!
Kid B: Yeah, like i said I'll help you out, and we can both play with each others toys.
After the announcement of tariffs, world markets saw Canada and China’s markets drop a couple points and the US’s surged a couple of points.
If you knew that market shift was coming and had a few billion in international markets and sold while the US surged, you made a shitload of money (at least, “shitload of money” from my perspective, because I’m a poorsie).
