I think Iranian leaders are brave and selfless enough to do that. If the jews and iluminati does not rule over the world, there will be no chain reaction. But even such possibility should not stop the restoration of justice and punishment (death penalty) for israel and jews.

There will be no destruction of all humanity. The danger of nuclear weapons are greatly exaggerated. In cold war both americans and soviets used enemy nukes to frighten the population and have the minds of people against capitalism/communism. In reality there is hundreds of nukes gone off in USA, and You are still living fine. In real war there will be maximum under 100 nuclear explosions, with less total yield than from all nuclear testings together. And modern nuclear weapons are more eco-fiendly, since they are more effective in using nuclear material than first generations of nukes.
