The two nuclear attacks on Japan in 1945 were on two cities chosen from a list of four recommended by "The Target Committee" at Los Alamos: Kyoto, Hiroshima, Yokohama, and the arsenal at Kokura. Later Niigata and Nagasaki were added. Weather and other factors caused Hiroshima and Nagasaki to be the target cities. Today's question is about one of those "other factors," why was Kyoto removed from the list first?
