Isolationism

Isolationism is the political and economic policy of avoiding involvement in international affairs. It is a strategy of protectionism which generally seeks to avoid economic entanglements with other nations. It is often used to protect a nation's resources, economy, and citizens from the perceived dangers of international relations.

Isolationism is not synonymous with xenophobia, but rather a rejection of the idea that a nation must rely on foreign influence or support to remain strong. Examples of successful isolationist nations in modern history include North Korea and Cuba.
