A nation practicing isolationism stays out of relations with other countries and concentrates on its own business at home.

The United States tried to maintain a policy of isolationism — staying out of other countries’ politics — until World War I and even beyond. But World War II and the Cold War ended that. The world keeps shrinking, and governments find it difficult to practice isolationism. Nowadays, nations find they have to get involved in other countries' problems, sometimes to protect their own interests and sometimes for humanitarian reasons.
