SECRETARY OF WAR HENRY STIMSON NOT LONG AFTER TRUMAN TOOK OFFICE, STIMSON HANDED HIM A MEMO THAT TOLD OF THE RESEARCH BEING CONDUCTED ON BUILDING A BOMB

POTSDAM GERMANY GROVES WIRED THE NEWS OF THE BOMB’S SUCCESS HALFWAY AROUND THE GLOBE TO PRESIDENT HARRY TRUMAN TRUMAN WAS A CHANGED MAN

OPTIONS STAGE A DEMONSTRATION OF THE BOMB FOR JAPANESE LEADERS OPPENHEIMER’S OBJECTIONS

HENRY STIMSON “I believe than no man, holding in his hands a weapon of such possibilities for accomplishing this purpose & saving those lives,could have failed to use it and afterwards look his countrymen in the face”

IKE “I told him (Stimson) I was against it on two counts. First the Japanese were ready to surrender and it wasn’t necessary to hit them with that awful thing, Second,I hated to see our country be the first to use such a weapon.”

RALPH BARD ‘I have a feeling that before the bomb is actually used against Japan, that Japan should have some preliminary warning of say 2 or 3 days in advance.”

JAMES FRANCK “If the US were to be the first to release this new means of indiscriminate destruction upon mankind, she would sacrifice public support throughout the world, and precipitate the race for armaments.”

WHY DID WE DROP THE BOMB? CASUALTY FIGURES FROM IWO JIM AND OKINAWA THE COST OF BUILDING THE BOMB THE SOVIETS
