A lot of people seem to have lost the thread when it comes to nuclear weapons. They think that nuclear weapons are like other weapons, and are designed to be used in war. But this is pure mental inertia. According to all the evidence available, nuclear weapons are anti-weapons, designed to prevent weapons, nuclear or otherwise, from being used. In essence, if used correctly, nuclear weapons are war suppression devices. Of course, if used incorrectly, they pose a grave risk to all life on Earth.
