Earlier quoted context omitted.
Elon and Bezos aren't more powerful than Kuwait. Kuwait is a sovereign government, with authority to write laws, raise an army, and do whatever it wants with its 5M+ citizens (draft them, imprison people, execute people, etc.) with pretty much no consequence unless they're absurdly reckless. There is more to power than money.
Kuwait cannot do any of that unilaterally. They are a vassal state in the american hegemony.
Whatever happened to just calling a country an ally? "Vassal state in the American hegemony" does sound a lot cooler I guess.
