Gaddafi’s Libya didn’t seem to fit any of liberal, free, non-oppressive or democratic.
That’s the point: your “well they deserved it” excuse is nonsense. Taking your arbitrary definition of “bad” countries at face value, all NATO interventions have done is make situations worse. Its actions are much more consistent with destroying regional economic competitors than with any sort of good faith effort to help anyone.
And all that is setting aside how the U.S. and its allies have destroyed any “liberal, free, non-oppressive” countries that don’t adequately toe the U.S. line (see Indonesia and Chile, among others). The countries that remain have to choose between being subservient to the U.S. (to varying degrees) or becoming the type of state liberals like you deem deserving of wholesale destruction.
that intervention was based on a UN Security Council resolution, which no member (not even Russia or China) opposed
Russia, China, and three other states abstained, and only NATO countries actually dropped bombs.
