Yes, exactly. It's pretty obvious what the thinking process is too. If you're the bureaucratic aristocracy of a nation of people of which there were 50m in the world, this restricts your power and resources to merely what 50m can do for you. If you instead change your nation of people to the whole world instead, you now get access to the resources and power that 7b people can give you. This global bureaucratic aristocracy sees nationalism as a restriction on their power and thus they immediately kill it. To the bureaucratic aristocracy, there are two kinds of people in the world: a ruler of the world or a person who serve the rulers. Any other group doesn't exist (or shouldn't) in their eyes.
