Hiroshima_ The World's Bomb - Andrew J. Rotter [157]
So the Americans would go it alone, testing weapons openly at Bikini in the summer of 1946 and again, at Eniewetok atoll in the Marshall Islands, in the spring of 1948. The latter series of tests in particular signaled to the Soviets that the United States had enough atomic bombs to afford the luxury of detonating three of them just to see how well they worked—and indeed one of them yielded 49 kilotons, easily the most powerful bomb yet. The Russians, and for that matter the British and others, could glean what clues they wanted from the tests, but there would be no decision to release atomic information. ‘It was [Baruch’s] ball, and he balled it up,’ wrote a disgusted Acheson. The United States hid behind Groves’s misplaced faith that the Soviets were years away from developing a bomb, hoping, somehow, that its nuclear monopoly would preserve its security and that of Western Europe, hoping, somehow, that its scientists had caught lightning in a bottle, a feat of genius, technology, and good luck that would be impossible for others to duplicate.35
This was wishful folly. But so too, in all likelihood, was the hope of Stimson, Lilienthal, and Acheson that an international agreement that envisioned, even in the short run, an American nuclear monopoly might dissuade Josef Stalin from building his own bomb. In the way that the American decision to drop the bomb on an enemy’s city was largely determined by Franklin Roosevelt’s decision to develop the bomb in the first place, so also was the Soviets’ resolve to make a bomb of their own established with unbreakable momentum by Stalin in August 1945, and perhaps even with Stalin’s authorization of a small nuclear project in spring 1943. The bomb was central to the Cold War; the Soviet leadership felt it as acutely as did the American. Stalin was not certain that the atomic bomb would prove, in itself, a militarily decisive weapon in a future war. Officials from the Soviet embassy in Tokyo who visited Hiroshima in September 1945 reported that, although destruction was great and death plentiful from the bomb, the effects of the bomb generally had been exaggerated by the Japanese press. Of course, as long as the Russians lacked the bomb they tried to reassure
