As compared to the Westerners of the time? Yes, the communists were much, much worse. They were mass murderers, rapists and torturers of men, women and children.Were the communists worse than America, though? (and by “America” I mean usury, sexual degeneracy, feminism, etc.).
You can take the long view if you like but the real analysis is for the average soldier at the time of the battle determining whether his fight is just or not. And against the communists of the Korean war era the fight was absolutely just. American troops may have done some very unpleasant things but they were a far cry from the absolutely unimaginable horrors that the communist regimes visited on their people. Folks like to whitewash the quiet pogroms that occurred in the places where the communists won and focus instead on the "traditionalist" nature of the countries afterward. Maybe if the dead could speak their piece then folks might see things differently.
Who holds the balance of morality presently is an entirely different debate.
Even a ruthless luciferian oligarch occasionally has to kill an evil warlord sitting on something valuable. The decisions at the top have no moral bearing whatsoever. But occasionally the troops find themselves lucky enough to be killing genuinely bad people....
But do keep trying, I really do think there has to be a war the US was on the right side of, if for no other reason than there are just so many military attacks by America. Over 100 since WW2.
