Yes they were screwed and lots of people did die unnecessarily. However, Saudi Arabia wants nukes, Shinzo Abe (ex Japan PM) said Japan should get nukes, the future of the long term program of Iran is still unsettled. Apartheid South Africa had nukes and only gave them up because they didn't want the native Africans to have them. The problem becomes as more and more countries develop nuclear weapons, the risk of conflict using them grows higher. Already we have a long term conflict between Pakistan and India where both nations are nuclear armed and I very much doubt Pakistan's nuclear security as anywhere as good as say America's or China's. What would happen if 20 or 30 or 40 countries had nukes? They would threaten to use them over every small thing and eventually I guess someone would use them, and who knows what happens then.
