Redmanfms:
North Koreans tested their nuke last year. It was not under Clinton Administration. It was the 7-th year of G. W. Bush being in the office.
A little bit of what G. Bush got in NK issue and how he handled that you can find here:

The result? In 2003 North Koreans stated that they came out of the agreement and resumed working on their nukes.
They wanted “no attacking them guarantees” from the USA.
They wanted direct talks with the USA. They wanted assistance in energy and food supply.
The Bush Administration did not want to provide any of those.
In the end, North Koreans got all of those.
You may call it NO cooperation, there was capitulation to the will of a totalitarian dictator.
But the dictator is happy.
