That kind of out-of-the-blue decapitation first strikes are not prevented by security measures. There simply is no way you can secure any halfway open society against an out-of-the-blue atomic attack. In the same way you might as well abandon any thought of securing your society against political assassins going after soft targets like newspapers or airports.

The thing that prevents this from happening is that most people with access to atomic weapons have a strong vested interest in the continued survival of industrial civilization.
