I don’t think Trump really wants to attack Canada. Even if he is serious about enacting them, he is more likely to present and try to force them using an economic war … things like tariffs or restrictions. What was done against Russia recently. Most of Canada is very close to the border with the US, and their economy is significantly dependent on trade with the US. In other words, he does not need to attack.
However, it is also true that economic wars often turn into physical wars if the restrictions prove to be very crippled. Japan attacked Pearl Harbor as the US refused to sell them oil, and South revolted against the north in the north due to tariffs on capturing its economy. I understand worry in that light. He can be so fed up with the Canadian American sanctions that they actually attack America.
I do not think there is a great possibility of a Canadian invasion of America in 1812. However, if the Canada is severely hurt by the US sanctions, they have allies that can approve of the US in turn, and it can start a chain reaction, where the rest of the world has to punish the restrictions and tariffs in the US to punish us what we are doing for Canada if they see it as a gross or peak. This means that we will be a Paria state like Russia and international businesses, and American businesses working abroad will be forced to shut down, US property may be frozen abroad, etc.
The worst situation is likely that we are all being killed by Canada, but have left both Canada and America’s economies in the hut, but with Canada, there is possibly getting a lot of sympathy and international assistance to avoid becoming a third world country throughout the night, and the US universally dismissed the European Union, Russia, and China, which is sometimes assisted for a significant situation on the world platform.
