BRIGADIER GENERAL CARTER CLARKE (The military intelligence officer in charge of preparing intercepted Japanese cables - the MAGIC summaries - for Truman and his advisors)
"...when we didn't need to do it, and we knew we didn't need to do it, and they knew that we knew we didn't need to do it, we used them as an experiment for two atomic bombs."
Quoted in Gar Alperovitz, The Decision To Use the Atomic Bomb, pg. 359
