Ms. Choe is no bumbling idiot--I personally think she has it together for their side. She is a hothead. Having said that, she has been trained and educated intricately and is deeply familiar with the history and tactics of dealing with the Americans. From what I can see, Kim has not had any of his senior team executed or hauling cement and coal in the aftermath of Hanoi failure. He may be in a bind. For him to purge anyone, he risks losing some of his key players with knowledge and smarts. They will probably end up just picking out a lower-level few water boys and jockstrap carriers for symbolic punishment to be meted out. In their system, somebody has to pay for the screw up.
