By and large, nationalists are bound to be disunited when it comes to practical matters, because each one only truly cares about their interests (it’s right there in the name, “national interests” is what nationalist parties call their own interests).
They do seem united when it comes to promoting their “principles”, but that’s because the same propaganda slogans (“us good, them bad”, “less taxes”, etc.) work everywhere and so all nationalists sing the same song.
The only long-lasting relationship between nationalists is where one side is a subject of another, and even those are only stable as long as the power balance doesn’t change.
