That’s ridiculous. I say it’s loosely centralized in the US because it is. The UK, KSA, Israel, and many other nations have oligarchs in this power structure. The US doesn’t rule the world, plutocrats and defense/intelligence agencies do. The US only exists as a conceptual construct; it’s not a real thing. The unaccountable power and influence wielded by oligarchs and secretive agencies very much is.
I have never at any time said that “they are largely from outside the US”; that’s just something you made up. If you’re just going to keep inventing things I said out of your own imagination I’m going to get instantly bored of this conversation.
