I have to wonder if the Chosun Ilbo has even bothered reading what North Korea nuclear envoy Stephen Bosworth has written in the past in regards to North Korea policy before publishing this article:

A Foreign Ministry official who remembers Bosworth as U.S. ambassador in Seoul recalls, “In private meetings, he often expressed his distrust of the North Korean regime.” In a meeting held in 2005, he reportedly said North Korean leader Kim Jong-il is a very unstable man.

But despite such personal beliefs, Bosworth is regarded as a staunch advocate of negotiations who believes in settlement through dialogue. He used to say that if there is anything that can prevent the worst acts in the cheapest way, it is diplomacy.

He is also considered a principled negotiator, having remarked that success or failure in North Korea policy depends not on whether we trust North Korea but on how we can confirm whether it keeps its promises.

A diplomatic source said his appointment means that U.S. President Barack Obama is determined not to be dragged along by the North but to engage it resolutely, without surrendering principles as the Bush administration did.  [Chosun Ilbo]

We already know North Korea has no intentions of giving up its nuclear program and cannot be trusted to keep their promises.  The last nuclear deal fell through because North Korea would not allow verification of their supposed denuclearization.  What makes the Chosun Ilbo think that Stephen Bosworth can do any better?

If you look at what he has written before Stephen Bosworth has every intention of continuing the failed Bush North Korea policy and making it even worse.
