document f
...the atomic bomb itself was intensifying soviet - american distrust. the americans and the british had secretly developed the weapon for use against germany, but the nazis surrendered before it was ready. the manhattan project american code name for the effort to develop the atomic bomb had not been secret enough, though, to keep soviet intelligence from discovering a lot about it through espionage... stalin mounted a major operation to spy on his allies in the middle of a war and they were waging together is another indication of his lack of trust in them...
the soviet leader showed little surprise, therefore, when truman gave him the news that the united states had just eight days before successfully tested a powerful new weapon. he had learned about the bomb long before the new american president had done so. but stalin reacted strongly when the united states went ahead and used the weapon against the japanese three weeks later.... \war is barbaric, but using the a - bomb is a superbarbarity,\ stalin complained... learning how hiroshima had been destroyed... \hiroshima has shaken the whole world,\ stalin told his scientists, in authorizing a crash soviet program to catch up. \the balance has been destroyed... that cannot be.\
in addition to seeing the bomb as shortening the war and thus denying the russians any significant role in defeating and occupying japan, stalin also saw the bomb as a means by which the united states would seek to extract postwar concessions from the soviet union: \a - bomb blackmail is american policy.\
