My better judgement tells me Kim Jong-Un is just copying his father.
Recall that in 1994, Kim Il-Sung died, North Korea (like other Communist countries at the time) lost privileged access to Soviet aid and the Soviet market. North Korea was in famine. Kim Jong-Il made an IDENTICAL food for no-nukes deal with President Clinton. There is a famous photograph of former Secretary of State Madeleine Albright toasting the “Dear Leader” and giving him a basketball signed by Michael Jordan. We know what eventually happened.
Kim Jong-Un isn’t trying anything new or inventing a new idea for himself. All the thinking has already been done for him.
