The notion of mutual nuclear deterrence can certainly be defended, the best example being the Cold War during which no nuclear weapons were used (although things became pretty tense on a few occasions). However, I wonder just how true this logic is when we are dealing with non-democratic, repressive regimes who use religion in order to formulate policy. Self-destruction has never kept religious zealots from launching attacks against those they perceive as their enemies. Suicide bombers are the best example of this. Do you really think Israel should just sit by and hope that the Iranian mullahs will not extend such an attitude to their use of a nuclear bomb?
