Here We Go Again

The Six Party Talks are about to begin again with North Korea on September 13th:

The talks will start again after a 37-day recess called on Aug. 7 when the U.S. and North Korea failed to agree on Pyongyang’s right to a civilian nuclear program. During the recess, Washington and Pyongyang held direct and indirect contacts but have not significantly narrowed their differences. A South Korean official said there was no cause for optimism about the coming talks.

Is there ever a cause for optimism with North Korea?
