Will give brainliest answer. with the essential question.

After World War II, the consequences of the Soviet Union's victory over the Nazis were rejected, and a global containment of communism was elevated into a doctrine by President Truman. By the Cold War, we spurred the Soviet Union from exhaustion to great-power status, the atomic bomb, and space achievement. Our policies against communism in China had much the same effect there. The Cold War has also frozen the world into its immediate postwar postures and pre vented peace settlements in East and West. Since 1945 the United States has spent enough resources on the Cold War to make many ailing societies healthy, resulting in a dangerous weakening of our economy. We ourselves have submitted to the militarism we fought in two world wars and have gone far to create a United States dominated by the military. We have depleted our resources for peacetime living, while our competi tors have forged ahead with such technologies. We have sadly neglected the nation's poor, and the President's Great Society legislation, aimed at helping them, is suffering because of the expense of the war in Vietnam. By making anticommunism our life motive, we have fostered rightist fanaticism. We have forgotten the inexorable law of life that every social system is in constant evolution, and, now that the Cold War with the So viet Union has eased, we are preparing to wage one against Communist China. Is it too late for us to welcome China to the community of nations, avoid the final world war, and try to organize the unity of man.
