MacArthur? This MacArthur?
"General Dwight Eisenhower voiced his opposition at Potsdam. "The Japanese were already defeated," he told Secretary of War Henry Stimson, "and it wasn't necessary to hit them with that awful thing." Admiral William Leahy, President Harry Truman's chief of staff, said that the "Japanese were already defeated and ready to surrender….The use of this barbarous weapon at Hiroshima and Nagasaki was of no material assistance in our war against Japan."
General Douglas MacArthur said that the Japanese would have gladly surrendered as early as May if the U.S. had told them they could keep the emperor. Similar views were voiced by Admirals Chester Nimitz, Ernest King and William Halsey, and General Henry Arnold."
"Retention of the emperor, as MacArthur noted, was the main stumbling block to surrender. Truman was well aware of the situation. He referred to the intercepted July 18 cable as the "telegram from the Jap emperor asking for peace." His close advisors concurred. "
"As postwar U.S. intelligence reports made clear, the atomic bombs had little impact on the Japanese decision. "
