Well, Jerome, if we all in the Nuclear Weapon powers preventatively nuke ourselves in a First Strike -- as the doctrine of preventative Nuclear First Strike against Weapons of Mass Destruction logically requires that we must -- then all those dirty proliferators will no longer have any motive to build any Weapons of Mass Destruction to deter us. Proliferation problem solved!

Self-aimed Nuclear First Strike to destroy our Nuclear First Strike capability! It's the selfless and responsible mass geno-suicide strategy implemented for the good of the world.

Also, it exploits our current strategic advantage before our enemies can close the mineshaft gap!  Just look at the Big Board!
