Rhodes: I am working on a book that would try to cover the years ’45 to ’55. I just finished the first 400 pages; it is all the Soviet bomb story, because so much has come available, including the espionage part of it. But, now I would like to get going and just simply try to deal with the development of the hydrogen bomb. And, most of all, I would like to describe the Mike shot, when you guys all came to put that together. But you also worked later, right, on Romeo? What was Romeo?
