A 2002 report from The Lancet said that the DPRK actually pursued ‘aggressive and unsustainable strategies to maximise the output of its land, only 15% of which is arable’, which blatantly contradicts the ignorant (or willfully dishonest) anticommunists’ claim that the land is ‘underutelized’.

Now, regarding the malnourished millions factoid:

[D]espite a precarious economy, the end of systematic government provision of food to the population, and a decline in assistance from international organizations after 2001, the data shows that by the mid‐2010s, national levels of severe wasting, an indication of famine‐like conditions in the population, were lower than in other low income countries globally and on a par with those prevailing in other developing countries in East Asia and the Pacific.

Finally, seeing as how these anticommunists admitted that they ‘don’t want to deal with the population after the Kim’s are gone’, I have a sneaking suspicion that they would resort to something like this so that nobody would have to deal with the population ever again.
