Once you have embarked upon killing, does how you do it really matter? Vaporizing a person in milliseconds, gassing them to death, shooting them, blowing them up, it is all evil. My view has always been to avoid violence. However, when violence finds me, I prefer to get the job done as fast as possible with the minimum of impact to myself or my loved ones. If nuclear weapons provide me with that option, then so be it. Death by radiation is terrible. But then again, I have seen death by cancer and don't see nature as any more humane than man. War will always be a cruel and evil undertaking.
