This is ridiculous. All responsibility lies with Kim Jong-Un. If he wanted to, he could call Yoon Suk-Yeol today, and negotiate a deal to transfer the entirety of North Korea to the ROK in exchange for immunity, asylum in Switzerland, and a couple billion dollars for himself and his friends. He could then continue living his luxurious lifestyle while NK is slowly integrated into the rest of Korea through some variation of "one country, two systems for 50 years". The North Korean people would finally become free.
