The nation most in need of a good crop-dusting with anti-psychotic medication, North Korea, is engaging once again in what they imagine is cagey diplomatic manouvering.

Step 1: Suddenly declare you have something very nasty -- in this case, nuclear weapons.

Step 2: Angrily pull out of something diplomatic -- in this case, the 6-nation talks, in which all the other nations, including your allies Russia and China, have told you to dump the nuclear weaponry plans.

Step 3: Demand bilateral talks with the US to show you're the big dog you incessently fantasize that you are -- in this case, something you have no hope of obtaining.

Step 4: Cave in, and go back to the bargaining table when the next wave of lucidity hits.
