The Summit With North Korea: A Stumbling Block Appears

It appears that the North Korea-US summit has hit its first stumbling block. Today's lead article in the Post explains that the North's chief nuclear negotiator, Kim Gye Gwan, has threatened to cancel the summit in light of:

Kim Gye Gwan

1. Recent US/South Korea military drills
2. John Bolton's stated insistence that North Korea denuclearize in the same fashion that Libya did in 2004

When Qaddafi negotiated with the Bush Administration in 2004, I gather that he agreed to completely terminate Libya's nuclear program. Seven years later, he was overthrown and assassinated. I imagine that the precedent is not appealing to Kim and his regime.

This new development reinforces my question from yesterday: How can the US agree to anything short of total denuclearization, and how can the North Koreans make that commitment? It seems like an unsolvable puzzle to me, but perhaps the diplomats will be able to finesse it.

Here's a painting from a North Korean artist named Jong Choi. I found it via a Huffington Post article about North Korean art.
