What development after World War II reflected the United States' emergence as a global power and its commitment to international cooperation?

• A. The establishment of the United Nations.
• B. The Monroe Doctrine extending influence.
• C. The Bretton Woods collapse.
• D. Isolation from world organizations.

Answer: (A)

After World War II, the United States stepped into a leadership role that promoted working with other nations to prevent future conflicts and rebuild the world. The establishment of the United Nations embodies this shift. It was created in 1945–46 with the United States at the forefront, offering a formal framework for international diplomacy, security, and cooperation. This shows a move away from isolation toward a collective approach to global problems, with the U.S. helping to shape the postwar order. The other options don’t fit as well. The Monroe Doctrine is an older policy focused on American influence in the Western Hemisphere, not postwar global cooperation. The Bretton Woods system did establish important international economic institutions, but the idea here is the word “collapse,” which is not accurate for the period and concept described. Isolation from world organizations runs directly against the postwar trend of active engagement in international institutions.
