Final answer:
The concept that America should stay out of world affairs is known as isolationism, a policy of non-involvement in international issues. Historical trends show the U.S. oscillating between isolationism and active engagement, influenced by factors like protection of national interests and support for human rights. The debate continues as to whether America should maintain a global presence or focus solely on internal affairs.
Step-by-step explanation:
The notion that America should stay out of world affairs refers to the idea of isolationism, a foreign policy principle advocating for a country to refrain from involving itself in international conflicts, alliances, and issues beyond its borders. This policy aims to preserve a nation's sovereignty and avoid the entanglements and complexities of international diplomacy and war. Throughout history, America has grappled with the tension between isolationism and interventionism. Figures like George Washington warned against entangling alliances, while interventions such as the Marshall Plan after World War II have shown America taking a leading role in global matters.
During the early 20th century, there was a struggle between the desire to avoid foreign wars, as emphasized by the reluctance to join World War I, and the need to engage with the world to promote national interests and protect human rights. The intervention in Greece and Turkey's affairs during the Truman Doctrine era exemplifies the U.S. stepping up to support democracy and counter totalitarian regimes. However, there has consistently been a faction within the U.S. that prefers returning to an isolationist stance, which would minimize U.S. presence in world affairs and focus primarily on domestic issues.
The presence of U.S. military bases globally and the spread of American culture and consumerism (labelled as corporate colonialism) indicate the complex reality of America's role in the world. This duality of admiration and disdain for American influence underscores the ongoing debate over America's international involvement.
