Libya last year. Serbia before, Kuwait, Korea,
You gotta be kidding. This is why I asked for anyone who is not a self-serving jackal asking you for "help". And so you list prime examples of the very thing I pointed out!
Libya: a bunch of radical islamists trying to overthrow a secular thug in order to establish Sharia law and persecute everyone who is not them. You and NATO helped in hopes of gaining preferential access to Libyan oil fields. Next.
Serbia: a bunch of power-hungry "separatists" who would exploit any possible division to split their country into a buch of city-states if they could get away with it as long as it put them in charge. Not to mention that some of them used a clever strategy of breeding like rabbits to gain control of territory of their neighbours, which you and NATO whole-heartedly endorsed. So you stepped in and gave them "freedom" to be dependent on you and your allies! And oppress the Serbs. Then there is a whole litany of fabricated "war crimes" that you try to pin on the Serbs to bring them to heel (never you mind that NATO killed far more civilians in far more criminal fashion, like bombing passenger trains, etc). An exercise in disgusting, self-serving "righteousness" for profit. Next.
Kuwait: an absolute monarchy invaded by a next door thug over them syphoning his oil using lateral oil wells running under Iraq's border built by US corporations (you knew the reason for the invasion, didn't you?) and so you went and ... restored absolute, oppressive monarchy back into its "rightful" place, the great purveyors of "freedom" and "democracy" that you are! Oh and the lies and propaganda that went along with it! The tear inducing (and totally fake) "eye witness" testimony by an incognito daughter of the Kuwaiti ambassador before the Senate about babies murdered in their incubators... just priceless. Next.
Korea: you propped up a dictator so bloody and corrupt that half of his country preferred Soviet-style thuggery to his exploits! Or did you think that all these North Koreans who fought against you did it just for kicks? It was not until the 1990s when the last South Korean dictator was ousted, all the previous ones having been untouchable due to your whole-hearted support, the great lovers of "freedom" and "democracy" that you are. Next.
WW2: you ignored all the pleas for help while trying to profit from the war by strategically supplying both sides until you were outright attacked by the Axis, Japan having bombed Pearl Harbour and 4 days later Nazi Germany having declared war on you. You did not join out of any good will. Next.
WW1: a bunch of blood-thirsty empires fighting over which royal dick is going to be sucked by whom. There were no "good guys" in this war and so you cannot count it as "helping" anyone (other then yourself). Next.
Indeed, the Spanish American war, the subjugation of Philippines, etc etc. A long list of selfish, self-centered exploits of a greedy empire.
Some US military actions are deplorable and indefensible, but some of them are legitimate attempts to help defend freedom and democracy
Actually the distinction is quite different. All of the military actions of the US are (with the possible exception of WW2) self-centered profit and expansion of power seeking excercises but because of the chosen "national narrative" and "national mythos"
of the USA, i.e. "brave defenders of freedom and democracy" that your power elites use to hold the thing together, they are forced to pretend that the actions are to give liberties of the oppressed etc and so on to keep the populace appropriately opiated. Sometimes the mirage thus formed is more successful then other times. This is what is confusing you.
US = Imperialist and Everyone Else = Innocent Victims is a naive way of viewing the problem.
That is not the view. The view is far more straightforward: empires = imperialist, be they Roman, British, French, Russian or American.
What makes the difference however is all the hypocrisy of the US empire trying to paint itself as a peddler of "freedom" which makes it a particularly odious specimen.
