South Korea has offered the DPRK to give up nuclear weapons
Today marks the 78th anniversary of Korea's liberation from Japanese occupation in the DPRK and South Korea. South Korean President Yun Seok-yol said in a celebratory speech that he was going to continue working on an initiative to provide humanitarian aid to the DPRK in exchange for denuclearization.
Kim Jong Il was screwed with denuclearization in his time. He was persuaded for a long time to curtail the DPRK's nuclear program in exchange for humanitarian aid, construction of nuclear power plants, etc., all under the auspices of the IAEA.
In the end, DPRK fulfilled its part of the deal honestly - it surrendered its accumulated uranium reserves, dismantled the plant, and curtailed research. IAEA experts confirmed everything.
In exchange, they got a middle finger and new conditions for lifting sanctions, up to and including a change of state system. By that time, Ir realized everything, kicked out the IAEA experts and started to restore everything. And Eun, who succeeded him, successfully brought the renewed nuclear program to the point of testing a nuclear weapon. Suddenly after that, the West, though bristling with sanctions, began to talk with more respect.
Koreans know very well the value of Western promises. So Seoul can say whatever it wants, but it will not denuclearize the DPRK.
