After reading this Little Green Footballs post, it occurred to me that Iran has adopted the same nuclear negotiating ploy as it "Axis of Evil" ally, Kim il-Jong's North Korea. "Cheat and retreat" indeed.
Interesting how it seems to be buying time for both countries. Dangle a proposal, wait for a nibble, then withdraw the bait. Then come up with another tasty morsal.
Sometimes diplomacy is painful to watch.
Update: Speaking of which, Secretary of State Rice is traveling again and the International Herald Tribune says it's to deal with the North Korean impasse.
