I'm not sure that's true. I for one have no interest in being an American, and would consider the country occupied, and i believe there would be an active resistance. The thing to remember is that if Canada were attacked it would be under the auspices of a tyrant and an invader. One whose same character would be imposed on its own people, as do all tyrannies.
You're making a lot of assumptions here. the Op never explains why the US attacks Canada. Let's suppose Canada tried to invade the US, or allied itself with another country using Canada as a base for attacks against the US. In that case, Canada would become a legitimate US target. Then the question would be why Canada chose to ally itself against the US in the first place. If the reason is legitimate, then of course I'd fight on the Canadian side against US aggression. But if it turned out Canada had become a fascist state and the US invasion was a defensive act intent solely to destroy the Canadian government (notice I say government and not country) and then pull out, then I'd likely sympathize with the US side.
With so little information in the OP, we can only speculate. In fact, let's suppose the US were taken over by fascists that then decided to attack Canada. In that case again, it's not likely to be a simple war between Canada and the US, seeing that many Americans could end up fighting on the Canadian side against their own government. Make no mistake about it, while nationalists will fight for their country right or wrong, patriots will fight for what they believe is right, and for the best moral interests of their country which sometimes might mean fighting against their government for the good of their country. So if the US were ever taken by fascism, while US nationalists would be quick to join the US army to fight Canada, US patriots would likely join the Canadian forces... again assuming Canada was not taken over by fascists too. Again, more speculation. There are so many unanswered questions in the OP that the whole thing is speculation.
You might think that is an anathema of American democracy. But there are 2 strains that exist in the American consciousness. One of Republic and one of Empire.
And there is no imperialist strain in Canada? I'm not saying Canada is not an imperialist state or that all Canadians are imperialists. What I am saying though is that imperialist beliefs are present in the minds of at least some Canadians.
It was Imperial America that took Florida, Texas, California and the American Southwest by force arms, expelling indigents. All of our alliances are with the Republic of the United States, with the Empire of Pax Americana there are no treaties of any value.
You're absolutely right. And Canada sent troops to help the British in the Boer Wars. We participated in building the British Empire. Consider too that the principles of Apartheid were based on the Canadian Reservation system. I'm not saying just that they have similarities, but rather that those who'd developed the policy of Apartheid were in fact familiar with the Canadian reservation system and applied that knowledge to develop Apartheid in South Africa, which was really just a more extreme version of our reservation system. Consider too that Canada via the Canadian International Development Agency is in fact engaged in cultural imperialism abroad too, especially in its contracts with a particular Canadian contractor. I forget the name of the contractor, but must admit that I was shocked to find textbooks in Chinese bookstores funded by CIDA, that were clearly intent on cultural imperialism. Your hard earned dollars at work.
By nature they respect no borders and crave tribute. None of the agreements would be any more valid than those held by the Indians with their understandings that the U.S. would not expand west of the Mississippi.
And Canada has honoured its treaties?
There is a protective element in our cause here. The American Imperial character has never managed to gain true precedence over the Republic. But it would be naive to say that this does not exist.
Again, you're making many assumptions about the OP... nless you've read the novel already?
In fact if you look to the history of Republics and Empire, and specifically Rome, which in structure and architecture Washington has emulated, then tyranny finally triumphed over the democracy.. and immediately Rome started to dissolve from within, until the barbarians finally breeched the gates of the city, and Empire collapsed.
Yes, and the US empire is indeed collapsing. But let's not think for one moment that there is not an imperialist element in Canada.
I can look at other countries, Poland, Finland, the Balkans, the Benelux countries who have throughout their histories been in the shadow of aggressive imperial aspirations, yet have continued to reserrect themselves as sovereign states.
They were normally not aggressor nations, and so were less likely to attrct long-term hatred against them.
Not only do i think the idea of Canada would sustain itself under American occupation, but i believe the nation state itself would ultimately prevail.
Again, that would depend on various factors. The US would be stupid to occupy Canada long-term. It would just mean more casualties on both sides and increased hatred of and fear of the US in Canada and abroad. That said, a quick attack aimed at destroying the Canadian government and retracting immediately afterwards could be defensible depending on circumstances, if let's say Canada itself were taken over by fascism or extreme imperialism, etc. And of course the same could be said in reverse if the US ever fell to imperialism etc.
