 Japan, Hiroshima and Nagasaki, was a surprise to Japan. They didn't know we had those two bombs. And then if you look at what we had subsequent to that, we tested an atomic bomb in 1953 in the Bikini Islands and the atolls in the Pacific that tested at 1,000 times the force of what we dropped on Hiroshima. Now, nobody would know that if we didn't do those tests.
