No stupid question… it seems Trump is ready to invade (military) Panama and Greenland (red white blueland), so even if with Canada he always talk about economic war and annexing Canada blablabla…
What would happen if USA invades Canada? What would be the reaction of the Canada King (Charles III is the king of Canada)? The Commonwealth? NATO?
Yes that’s another really good point. Any sort of foreign support from Russia or China or Europe that brings weapons in would mean a permanent thorn in their side, Canada wouldn’t see peace for decades, if at all. Similar to the quagmire in Afghanistan and Iraq.
That’s in addition to how easily we could strike at their home territory in cross border raids, which will be even more unacceptable domestically.
