Nobody is doing the people of Iran any favors by trying to make deals with that feral regime.
What is it about petty third world tyrants that they have to prove they have the biggest schwartz?
(Chirac and Putin are included in the petty dictators class until they prove otherwise, and zip up their pants and stop acting as if they should get more respect because their countries already have nuclear weapons. Heck, Iran and North Korea are probably only imitating the ritual schwartz beating that we saw France go through in the 1990s, and what Russia is currently engaged in.)
