Canada

FYI, it's Arctic, not "artic"

If it was really about minerals and oil, why did Trump put a tariff on these things?

It's not like Canada was refusing to sell minerals to the US. Everyone was totally fine with selling them. It was Trump that decided "we don't need anything" from Canada.

An attempt to annex Canada won't make these things cheaper. You have to pay people to extract minerals from under the ground. In fact a lot of Canadians might refuse to mine those resources after and invasion and those sites would be a prime target for sabotage.

So tariffs make oil and minerals more expensive. Invasion makes them even more expensive and makes the supply chain incredibly unreliable. If it were really about minerals, then the US would just continue to do as it always has: just buy them.

Sure I'll grant you Trump is dumb enough to think that invading a friendly country might somehow make the resources cheaper to extract from the ground, he doesn't have a solid concept of paying workers after all. But if that's the case he's still stupid and he's lying when he says the US doesn't need anything from Canada, and also lying when he says it'll make the US look good on the map.

Not sure why people want to assume Trump is lying when he says dumb shit and further assume he has some other motive that might seem reasonable, but is also dumb shit.
