Explanation: World War I ended up being very expensive to the United States. Americas goal in becoming isolationist was to protect America from becoming involved in another European war, ( it didn’t work). Also America wanted to protect itself from socialism and communism coming from Europe.

Since the end of the Cold War, many of America’s closest allies have complained about the rise of American unilateralism, a tendency in Washington to take decisions without much regard for the interests or views of its own allies or the rest of the world.

During the 1930s, the combination of the Great Depression and the memory of tragic losses in World War I contributed to pushing American public opinion and policy toward isolationism. Isolationists advocated non-involvement in European and Asian conflicts and non-entanglement in international politics.

The battles of World War II are largely divided into the European Theater (Western Europe), Eastern Front, Mediterranean/North Africa Theater, and the Pacific Theater.

World War II had two primary theatres: The European Theatre and the Pacific Theatre. The European Theatre of World War II stretched across the entire continent, from the Atlantic Ocean to the Ural Mountains. It also encompassed campaigns in the Middle East and North Africa.
