"Rendering... nuclear weapons impotent and obsolete"

There's this:

I call upon the scientific community in our country, those who gave us nuclear weapons, to turn their great talents now to the cause of mankind and world peace, to give us the means of rendering those nuclear weapons impotent and obsolete. -- Ronald Reagan, Address to the Nation, March 23, 1983

and then there's this:

...a group of countries, led by Israel and the U.S., had been working since 1981 on a mega-secret project to develop and deploy a weapon system that can neutralize nuclear weapons. The highly advanced, space-deployable, BHB weapon system, code-named XXXBHB-BACAR-1318-I390MSCH, has extraordinary potential and is a key part of the West's deterrence strategy. For the past twenty-five years, the project and the scientists involved in it were kept in strict secrecy and their existence denied. The scientists rejected Nobel Physics prize and Nobel Peace prize nominations and have been repeatedly and deliberately the subject of intense military disinformation through the media in order to divert attention from their highly secretive work... ...Although we have only limited information, it appears that Iran's rapidly developing nuclear capabilities could be neutralized and rendered obsolete, as could the capabilities of other rogue countries... -- Thomas McInerney, Paul Vallely writing in Endgame: The Blueprint for Victory in the War on Terror
