Of course. Even more would apply to Mexico, and to a United World.

It would be interesting to see what Canada/Canadians would do/say if the US pulled its military protection and stopped buying Canadian goods full stop. Canadians are self-righteous, and like to think they “are better” than American. They have no military, no means of defense from an arctic threat from China/Russia, and no infrastructure to sells its oil/gas to any major nation other than the US. Could this change? Of course, but it would require years to implement, and they are so deep in debt, on an individual, provincial, and national level that it would require a shit ton of foreign investment…….Canada’s cooked. Trump knows it, the rest of the world knows, and Canadians may be finally waking up to it.
