What is isolationism in terms of foreign policy?

Isolationism refers to a foreign policy approach where a nation chooses to remain aloof from the political and military affairs of other countries. This means that the country does not engage in alliances or interventions in conflicts abroad, prioritizing its own interests and focusing on internal matters rather than international commitments.

The essence of isolationism lies in nonparticipation; it advocates for minimal involvement in international affairs, which is reflective of a desire to avoid the complexities and responsibilities of foreign alliances and engagements. This policy can stem from a variety of factors, including a desire to protect national sovereignty, avoid entanglement in foreign wars, or a belief in self-sufficiency.

In contrast, the other options pertain to policies that emphasize engagement, cooperation, or opposing trade specifically, differing fundamentally in nature from the concept of isolationism. These alternatives reflect a proactive stance in international relations, which isolationism distinctly rejects.
