Well - it depends on how one wants to call the result of the war.
I think there was not necessarily a winner; there was a stalemate/truce, with China guaranteeing North Korea to not lose, but not necessarily win either. That does not mean North Korea won, but I don't think one can necessarily say that they lost the war either.
I am fully aware of how the propaganda in North Korea works, but some articles are also heavily biased. The biggest danger to North Korea actually comes from the success model in South Korea, as well as the internet. The internet kind of nerfed Scientology (see what Ron Miscavige said and described how Scientology changed over the years, so if one of the big guys can quit, the whole business model they established decades ago, is dead and decaying). Sooner or later Kim Jong Fat will also lose out to the internet. You can not permanently cut off million of people, with the assumption they won't be able to understand how strategic lies work. It also does not work in Russia either, though Russia is of course nowhere near as isolated as North Korea right now.
