I am not unsympathetic to your point of view, and I can certainly see where you could draw these conclusions, though it is my opinion that you may have reached them while looking through "I really don't like Bush" colored glasses. I have always been under the impression that when North Korea met certain conditions, our relations with them would change. This, if I remember correctly, was the difference between the current administration and Clinton's. If I remember correctly (and I could be wrong), Clinton put no preconditions on negotiating with N. Korea and this is why they lambasted Clinton.
Regardless of how either of us feel or view the sitution, if North Korea does what they say they will do, and if they continue down that path, it is definately a positive step.
