b. Expansionist
c. Interventionist
d. Neutral

Answer 1

After World War II, the United States' actions such as occupying Japan, joining NATO, and helping organize the UN show that the U.S. adopted an interventionist approach to international relations, moving away from its earlier isolationist stance. The correct option is A.

Step-by-step explanation:

After World War II, the United States took several measures that reflected its foreign policy stance in the postwar era. Following its occupation of Japan, joining the North Atlantic Treaty Organization (NATO), and playing a pivotal role in the formation of the United Nations (UN), the United States demonstrated a clear shift from its previous isolationist tendencies.

These actions were indicative of an interventionist approach to international relations. At the time, the United States was no longer content to stay out of global affairs, instead actively engaging to shape the post-war world and counter the spread of Communism, thus marking the start of the Cold War era.
