Which is my point: if you don't care about "your" country, the theories don't go out the window. You might stay consistent and move instead of deciding that killing the invaders is what you do now.
My point is that at the end you won't have any place left to go, especially if a large part of the population behaves like you. No resistance whatsoever will make life much easier for invaders, so there will be more of them all around the world. The solution is not to flee, it's to eradicate the idea of prevailing using force or indoctrination.
That's all true regardless if your world is composed of houses, villages, countries, continents, or whatever else. What matters here is aggression, not aggression to countries, and focusing on countries only blurs the message.
That's why I pointed out that the position as stated is relevant only to the nationalist ideology.
