This 4D-chess argument fails to mention that the US would not need to get its ass kicked like that and look increasingly impotent to other global powers, huge losses of material aside, to leave the Middle East. You know, you could simply threaten with leaving and extort more money for not leaving. If you are seriously saying that the US needs to get humiliated in a war it itself artificially started to do so, that would be even worse and China certainly takes notes.

Never mind that the above comment is drinking the US cool-aid by completely ignoring that the interdependence between Canada and the US go both ways. Add to that, that Canada could expect serious support form Europe, Australia and who knows, competing major powers who see the chance to improve its reputation in former members of the American Empire. Canada isn't Cuba. Economic warfare against it would also cause the US to bleed, substantially, especially if coordinated with Mexico which would have a stake in the game as well. US Americans, especially MAGA supporters, aren't used to bleed for their imperial endeavors at the home front. Canadians on the other side, would be ready to accept quite a lot of beating as their own nation would be at stake against the US aggressor.
