Answer:
George Washington's Farewell Address in 1789 contained one major piece of advice to the country regarding relations with other nations: "avoid entangling alliances." Those words shaped United States foreign policy for more than a century.
Today some Americans think that Washington's words are still wise ones, and that the United States should withdraw from world affairs whenever possible. In truth, however, the United States has been embroiled in world politics throughout the 20th century, and as a result, foreign policy takes up a great deal of government's time, energy, and money.
If isolationism has become outdated, what kind of foreign policy does the United States follow? In the years after World War II, the United States was guided generally by containment — the policy of keeping communism from spreading beyond the countries already under its influence. The policy applied to a world divided by the Cold War, a struggle between the United States and the Soviet Union.
With the collapse of the Soviet Union in 1991, containment no longer made sense, so in the past ten years, the United States has been redefining its foreign policy. What are its responsibilities, if any, to the rest of the world, now that it has no incentive of luring them to the American "side" in the Cold War? Do the United States still need allies? What action should be taken, if any, when a "hot spot" erupts, causing misery to the people who live in the nations involved? The answers are not easy.
