What does the term isolationism refer to in the context of foreign policy?

Isolationism in the context of foreign policy refers to a strategy where a country intentionally avoids participation in international political or military engagements. This approach often emphasizes self-reliance and prioritizes domestic concerns over global issues. Historically, countries that adopt an isolationist stance seek to limit their involvement in foreign disputes, alliances, and conflicts, reflecting a desire to maintain sovereignty and avoid the complications and risks associated with international affairs.

The other options describe different foreign policy approaches. Active military involvement in conflicts signifies an engagement strategy, while a policy of trade restrictions pertains to economic interactions rather than political isolation. Forming alliances with foreign nations contrasts sharply with isolationism, as it entails active participation and collaboration with other countries. Overall, the key characteristic of isolationism is its emphasis on non-involvement in the affairs of other nations.
