> this is pure propaganda and is completely false statement, not grounded in reality. US has no problem protecting despotic autocracies like the Pinochet's junta in Chile or Saudi Arabian theocratic monarchy (a birthplace of islamic wahhabism).
No, it is not false. Geopolitics is about lesser evils and raw needs, not perfect ideological consistency. Any country stupid enough to care about that would not last very long, and so none of them do.
The US has spent an extraordinary amount of money protecting freedom of navigation, discouraging conquests, and in many cases halting genocide. I'm not providing citations, if you're confident enough in your opinions to call what I said "pure propaganda" surely you can name them.
> The actual goal of military is to protect the status of USD as a global reserve currency and ensure all important nations are its vassals, fully subordinate to the US government.
The goal of the military is to achieve American objectives by force, like every other military.
> The underlying reason is America is printing trillions of dollars out of thin air, not backed by anything, other than the threat from US military, so vassal states keep recycling their earned surplus currency into USD bonds and treasuries
...you know, good luck with that, I'm done here.
Quick guess without looking it up: for how many decades were we protecting liberal democracy in Korea and Taiwan before they had their first free elections?
Yes you're completely correct, our goal is to protect liberal democracy (unless it happens that protecting liberal democracy is in conflict with our economic or security interests, at which point we immediately stop giving a fuck about it)
