 proxy wars. In February 1946, George Kennan sent a telegram to the State Department that painted a foreboding picture of the Soviet Union. We have here a political force, Kennan wrote, committed fanatically to the belief that it is necessary that the internal harmony of American society be disrupted, our traditional way of life be destroyed, and the international authority of our state be broken. A subsequent State Department report urged the federal government to resist vigorously Soviet efforts to expand into areas vital to American security. The report called on America to assist all democratic countries endangered by the USSR. President Harry Truman implemented these recommendations in his containment policy, based on what became known as the Domino Theory. The theory posited, the fall of a single state to communism would precipitate the fall of surrounding countries like a row of dominoes. The U.S. therefore needed to contain communism by supporting non-communist governments economically and militarily. The contest between the American and Soviet empires is called the Cold War, because instead of fighting directly, the states waged proxy wars in other countries. The key battlegrounds were economically undeveloped regions, dubbed the Third World. The First World being Western democracies, and the Second World being communist dictatorships. The American and Soviet governments supplied weapons to opposing sides in third world conflicts, vying to install puppet governments. The Cold War seemed to usher in a new type of imperialism, but it actually resurrected the ancient formula of the Persian Empire, which installed pliant local governors, known as satraps, to provide the illusion of autonomy in conquered provinces. The newly established CIA orchestrated regime changes in dozens of countries, often installing brutal dictators such as the Shah of Iran and Mobutu Sese Seko in Zaire. The strategy backfired constantly. American backed dictators commonly faced coups and assassinations, and their oppressive policies seemed to confirm Soviet critiques of America, even though Soviet backed dictators were no less brutal. Instead of containing communism, proxy wars exacerbated third world conflicts. Some even escalated enough to draw the American military into combat. For example, the US originally supplied weapons to the French military in Vietnam. After France was driven out, President John Kennedy sent equipment and troops to train the anti-communist forces in the South. Within a few years, American soldiers were fighting directly. The Vietnam War spanned three presidential administrations, expanded into Laos and Cambodia, and resulted in the deaths of 58,000 Americans and millions of Southeast Asians. It was also America's first military defeat, as communists took power in all three countries. Yet to the surprise of foreign policy experts, no other dominoes toppled. The Cold War ended in 1991, securing America's global hygieny. Proxy warfare continued, but with Russia's evil empire defeated, America lacked a unifying enemy. This changed in 2001, when George W. Bush declared war against terror.
