The American Experience | Race for the Superbomb | Nuclear Blast Mapper My most passionate activism has been for disarmament. I went to the UK once just because I had been so enamored of the Campaign for Nuclear Disarmament (CND). I helped Helen Caldicott and others found Physicians for Social Responsibility when I was a pre-med and medical student. In large measure, I was “turned” by my exposure to the BBC film “The War Game,” a ground’s-eye neighborhood view of the effects of a nuclear attack that I believe was banned in the UK for many years because it was so disturbing. (Do you remember the network media event of “The Day After”? This was a decade earlier, and without the Hollywood bathos and glitz.) Disarmament activism works best when it brings the effects of a nuclear blast home to your dinner table, as does this site. Here is what happens to my part of the country from a 25 megaton air blast.
