The next generation of North Koreans will again be smaller than their southern counterparts as underfed mothers are in an inescapable cycle of malnutrition, birthing low-weight babies.

This is a problem not affecting the South Korean population (who field the fifth most powerful military in the world, per GFI.com)

Since 1953 at the DMZ, the US, ROK, and DPRK assigned their tallest MPs as sentries and symbols of their national strength. Once the ROK and NORK MPs were able to stare at each other eye to eye at the DMZ.

No more.

Years ago when Egyptian President Hosni Mubarak announced that one of his sons will succeed him as Pharoah, the people of Egypt said "No way!" and he was ousted.

The oppressed people of North Korea see the dynasty gelling, but are powerless.

Unlike North Korea, Egypt is unable to contain ideas coming in via the internet or international trade, so Mubarak was toppled, only to be eventually replaced by another military dictator, al-Sisi.

Note that Vladimir Putin sends aid to Iran, but not to North Korea, and a new highway bridge was recently constructed connecting the two countries. Previously, only a single railroad line connected the two pariah states.

To Pyongyang, Vlad the Impaler sends WMD technology and other military secrets and weapons.

Little or nothing humanitarian.

Putin doesn't care one whit about the North Korean population, other than being cannon fodder.
