28.2 The cold war  (Page 2/17)

Although the United States and the Soviet Union did finally reach an agreement at Potsdam, this was the final occasion on which they cooperated for quite some time. Each remained convinced that its own economic and political systems were superior to the other’s, and the two superpowers quickly found themselves drawn into conflict. The decades-long struggle between them for technological and ideological supremacy became known as the Cold War    . So called because it did not include direct military confrontation between Soviet and U.S. troops, the Cold War was fought with a variety of other weapons: espionage and surveillance, political assassinations, propaganda, and the formation of alliances with other nations. It also became an arms race, as both countries competed to build the greatest stockpile of nuclear weapons, and also competed for influence in poorer nations, supporting opposite sides in wars in some of those nations, such as Korea and Vietnam.

Containment abroad

In February 1946, George Kennan, a State Department official stationed at the U.S. embassy in Moscow, sent an eight-thousand-word message to Washington, DC. In what became known as the “ Long Telegram ,” Kennan maintained that Soviet leaders believed that the only way to protect the Soviet Union was to destroy “rival” nations and their influence over weaker nations. According to Kennan, the Soviet Union was not so much a revolutionary regime as a totalitarian bureaucracy that was unable to accept the prospect of a peaceful coexistence of the United States and itself. He advised that the best way to thwart Soviet plans for the world was to contain Soviet influence—primarily through economic policy—to those places where it already existed and prevent its political expansion into new areas. This strategy, which came to be known as the policy of containment    , formed the basis for U.S. foreign policy and military decision making for more than thirty years.

As Communist governments came to power elsewhere in the world, American policymakers extended their strategy of containment to what became known as the domino theory    under the Eisenhower administration: Neighbors to Communist nations, so was the assumption, were likely to succumb to the same allegedly dangerous and infectious ideology. Like dominos toppling one another, entire regions would eventually be controlled by the Soviets. The demand for anti-Communist containment appeared as early as March 1946 in a speech by Winston Churchill, in which he referred to an Iron Curtain    that divided Europe into the “free” West and the Communist East controlled by the Soviet Union.

The commitment to containing Soviet expansion made necessary the ability to mount a strong military offense and defense. In pursuit of this goal, the U.S. military was reorganized under the National Security Act of 1947. This act streamlined the government in matters of security by creating the National Security Council and establishing the Central Intelligence Agency (CIA) to conduct surveillance and espionage in foreign nations. It also created the Department of the Air Force, which was combined with the Departments of the Army and Navy in 1949 to form one Department of Defense.
