<Here. (Thanks to Andrew Sullivan):

...My main reason for opposing war was that I believed that Saddam was deterred from using weapons of mass destruction as both the United States and Soviets were deterred during the Cold War. However, in reviewing the 1962 Cuba crisis, I found that when the United States was putting pressure on the Soviets to remove their missiles from Cuba in 1962, Castro was screaming at Moscow to launch a nuclear attack on the United States from Cuba -- even though Castro knew that Cuba would have faced destruction from the U.S. response. This unnerved Khrushchev because he knew the conflict would then probably escalate to full-scale nuclear war. Khrushchev was perfectly willing to threaten to use nuclear weapons but was constrained from using them; Castro, however, would not have been so constrained had he had them.

I also posted this on the Backup Board:

"If a day comes when the world of Islam is duly equipped with the arms Israel has in possession, the strategy of colonialism would face a stalemate because application of an atomic bomb would not leave any thing in Israel but the same thing would just produce damages in the Muslim world", Ayatollah Ali Akbar Hashemi-Rafsanjani told the crowd at the traditional Friday prayers in Tehran.

It is part of the mantra of the opponents to war that we could easily prevent Saddam from doing anything bad by threatening him with eventual retaliation. I'm not sure this works on megalomaniacs. How many cities are we willing to bet?
