On Sunday, at the UN Open Day, it was great to see so many people young and old, from across the globe, reacting to and discussing my exhibition. I personally talked to people from a great many countries and the usual language problems did not seem to matter as the images spoke to them across language barriers.

I will always remember one old Japanese man looking at one of my photomontages of a fist breaking a missile who raised his own fist as if mirroring the image and smiled to himself.

   The photomontages began to be used in campaigns across the world. I saw pictures of a mural in Australia, a photograph in a Soviet newspaper and a poster on a wall in Japan that had all used the photomontages. Through the collision of a visual technique I had developed over ten years, and a mass movement, I was able to produce a public art that developed its own momentum through anti-nuclear networks. The images had become placards for the street.

I believe that the image of objects that we oppose should be broken up, shattered by opposing imagery. We must find key images enabling us to prise open and reveal the hidden mechanisms of oppressive regimes.
