Roosevelt wanted Russian participation in the war, particularly on the Pacific front Russia occupies half of Europe and will not move Russian fear of invasion from the West Russian sacrifices in WW II - they bore the brunt of German attacks Stalin makes promises of democracy (quickly reneges) Atomic Bomb &gt; President Harry Truman announces the Hiroshima bombing Announcer: Good evening from the White House in Washington. Ladies and gentlemen the President of the United States. Harry S. Truman: My fellow Americans, the British, Chinese and United States governments have given the Japanese people adequate warning of what is in store for them. The world will note that the first atomic bomb was dropped on Hiroshima, a military base. If Japan does not surrender, bombs will have to be dropped on her war industries and unfortunately thousands of civilian lives will be lost. I urge Japanese civilians to leave industrial cities immediately and save themselves from destruction. Atomic Bomb &gt; Was it necessary? Yes: necessary to force Japanese surrender saved millions of American lives No: Japanese may have been ready to surrender anyway Truman didn't wait for the Russians to enter the fight which would have ended the fighting Truman true purpose was to intimidate the Russians Too horrific; destroyed thousands of civilian Japanese lives The Strategy of Containment &gt; George Kennan Its main concern is to make sure that it has filled every nook and cranny available to it in the basin of world power. These considerations make Soviet diplomacy at once easier and more difficult to deal with than the diplomacy of individual aggressive leaders like Napoleon and Hitler. On the one hand it is more sensitive to contrary force, more ready to yield on individual sectors of the diplomatic front when that force is felt to be too strong, and thus more rational in the logic of rhetoric of power. On the other hand it cannot be easily defeated or discouraged by a single victory on the part of its opponents. And the patient persistence by which it is animated means that it can be effectively countered not by sporadic acts which represent the momentary whims of democratic opinion but only by intelligent long-range policies on the part of Russia's adversaries -- policies no less steady in their purpose, and no less variegated and resourceful in their application, than those of the Soviet Union itself. In these circumstances it is clear that the main element of any United States policy toward the Soviet Union must be that of a long-term, patient but firm and vigilant containment of Russian expansive tendencies.
