You’re right. If you see the world not as a conflict between nation states but as a class war all of this makes a lot more sense. This is not to say that nation states don’t matter. They are absolutely still used by the ruling class to maintain order and justify their actions as a “defense of our nation and culture”. Fascism has no hard rules or ideologies. It is used to defend capitalist interests and power. It is why we are seeing the rise in far right politics in the west.

The capitalist class does not know borders; it knows class interest. Fascism is the defense of this interest in the face of capitalism internal contradictions.
