Here Come the North Koreans?

Some thoughts at the Diplomat on what a dissolution of the Korean People’s Army might mean for private military firms around the world:
The end of the Cold War led to the largest military demobilization since the final days of World War II. Between 1988 and 1999, the Soviet Union alone reduced its military personnel by about three million men (although some of these found employment in the armed forces of successor states). The rest of the Eastern bloc went through a similar experience, followed by the NATO alliance.
This demobilization left a massive, floating population of trained soldiers, often without any good economic prospects. This pool of military labor helped feed the growth of private military firms, operating in Africa, the Middle East, and elsewhere. In some cases, Russian and Eastern European soldiers served on different sides of the same conflicts, often bringing equipment along with them.
Given the changing nature of military technology, it is unlikely that we’ll ever see a global military demobilization of similar magnitude. Mass armies have gone out of style, except for in one place: the Korean Peninsula.
