North Korean apologists (Putin isn't the only one, I know a few in real life) do not maintain that North Korea is a nice place to live, though they do try to paint a picture of relative freedom and happiness. (Things like the kidnapping of Japanese and ROK citizens, the gulags, the killings of political prisoners and the horrible elements of totalitarianism and the Juche ideology are conveniently ignored).
Rather, the apologist line is that the patently obvious malnutrition, economic desperation, and military exercises against neighbours do happen, but that they are entirely the cause of American aggression.
As with most persistent apologetic narratives for dictatorships, there is a grain of truth in this evaluation.
North Korea has indeed been subject to economic deprivation, demonization, and political isolation by the American government, both in the context of the geopolitical struggle of the cold war with the Soviet Union as well as the general recent security strategy of the US government in response to changed priorities in east Asia.
Still, I don not think this excuses the North Korean government for it's tendency to treat it's citizens so poorly, or its hypocritical and violent maintenance of a patently unfair and failing ideological and economic system. Blaming these all on America or turning a blind eye does nothing constructive in reducing the conflict, and quite honestly, attributes way too much agency to American policy, and not nearly enough to Chinese, Soviet, and North Korean decisions. The guilt weighs heavily on all actors involved.
