> USA is an advocate of very specific stability. "Free world" is a hyperbolic but US is still a huge global power.
> In cold war it was obvious there were two sides, and the other was obviously more free than the other. Go ask for example Estonians, Lithuanians or Latvians who they enjoyed the yoke of the USSR.
You could also ask a Guatemalan how they enjoyed living under the US installed military dictatorships (which came out of a US supported coup after democratic elections resulted in a win for the left). Things are by far not as clear cut. Both blocks supported atrocious regimes if it was in their economic interests and worked against "the other side". That we largely only hear about one side shows how well the propaganda was/is working.
