Do not be discouraged by Kim Jong-un's unification statements
There is a unique relationship between denuclearization, human rights and unification. The only way to achieve denuclearization and end the human rights abuses being committed against North Koreans is by achieving unification, which is a new Korea determined by the Korean people achieving the 'Korean Dream' - a United Republic of Korea. Perhaps counterintuitively, it is the focus on human rights that must lead to unification, and only when unification is achieved can there be denuclearization. And the connective tissue among the three is information.
