Answer:
Containment refers to a policy of actively containing the spread of communism, especially the Soviet Union, during the Cold War. The United States aimed to limit Soviet expansionism by providing military and economic aid to countries threatened by communism. The policy of containment required the US to involve itself in the foreign affairs of European and Asian countries, and sometimes even engage in military interventions.
On the other hand, Isolationism refers to a policy of remaining detached from global conflicts and avoiding entanglement in the affairs of other countries. Isolationism was most prominent in the 1930s, when the United States sought to avoid involvement in the World War II. The policy of isolationism required the US to distance and protect itself from any global conflict, and sometimes even to remain neutral on conflicts involving European and Asian countries.
In summary, while containment requires the US to involve itself in foreign affairs and global conflicts, isolationism requires the US to remain detached and avoid such entanglements.
