Nowadays, nobody even pretends to not be a liar, from any side. There is no debate that even attempts to look at the facts - it's vibes all the way down and fuck you if you don't agree, only money and guns matter. In the long run, this can't hold.
It's always held, management just changes. Money and power are two fundamental constants to human nature.
That order was not perfect, but the alternative is going back to the naked power struggles of the XIX century, which ended in global carneficine - and the next time it will be so much worse.
Actually, I don't think that's necessarily the case. Look at the Chagos deal: that's the new reality created by international organizations catching up with the naked power of the original occupation, and pushing it into a corner. Again, far from perfect outcome (why Mauritius, etc etc), but quite a step forward from brutal colonialism. Humanity wins some and loses some, but at least we're still in the game. If we just give up and accept that might makes right, we slide backwards into the jungle.
Spoiler: The CIA was formed around rich people's interests and continue to represent them, not in fact, the American people. Harsh reality but helpful to know.
