North Korean expertise

The North Korean President, Kim Jung Un, has said that he'll dismantle his nuclear weapons site in front of observers. This may in part be due to the site partially dismantling itself when a mountain collapsed following a large number of tests in the past year. However, it is interesting to ponder the future of the physicists and engineers employed on the North Korean project. They are experts in this important field and one can't help but wonder if their expertise is a marketable commodity. Can you think of any countries around the world who might want to avail themselves of this skill, paying the impoverished North Koreans plenty of much wanted hard currency?
