The countries that have nukes have not used them--excepting the US in 1945. The Israelis have had nukes for over 20 years. They haven't used them. More people having nukes increases the likelihood that one of the new 'players' will get 'offensive' with them and then lotsa people will start to use nukes. If I have a choice to trust Israel and the US with nukes or to trust Iran with nukes--there is no question who I will trust. My preference is that there be none of the goddamned things on the planet.

Iran's leader has already shown himself to be a crackpot. He has already advocated mass murder. What is there to reason with? And why? The fucker should become one with the Earth. Soonest, IMO.
