Well I am talking about before a military conflict erupts. I’m talking about what is in the interest of the people, when they are looking at a potential military conflict.

In the case of Ukraine, being peacefully “relocated” to Russia seems much better than what is happening now. Before the war the reputation of the Ukrainian government was not much different from the reputation of the Russian government. If it were me as a Ukrainian in that situation I would not be in favor of fighting.

Now Poles “relocating” to Germany without any conflict seems like it would not have ended well for them. Poles at that time violently resisting made sense. Refusing a land bridge agreement to avoid the need for violence, perhaps not, but resisting occupation, sure. But that is because the two governments at that time actually were very different, one being extremely ethno-centric. This does not really apply to America or Russia. If the Ukrainians were born in Russia nobody would notice, they are well within the ethnic cloud of the Russian state. Same with Canadians in America.

I don’t think allegiance to a nation means much these days. If anyone can move anywhere and not assimilate, who even really cares at that point? Should Canadians accept the human makeup of their nation changing quickly and drastically, no problem, but getting a different government is the end of the world? Doesn’t really make sense to me. Does make sense why governments put out propaganda to rile people up, though, since it is clearly in the interest of the government to resist in all such cases.

  What if the new government also imply that you have to change our religion? What if the new government does not believe in "free enterprise" and will TELL you which company you will work for. What if the new government change the sports teams you like? What if the new government change the language you speak. 

  See for the example https://en.wikipedia.org/wiki/Alsace#Timeline  . Notice how the official language suddenly changes when a new "government" from a different nation take over. Are you so sure that the French Canadians will not have a problem with suddenly English potentially been the official language?
