What was the main objective of President Truman's 'Point Four' plan?

President Truman's 'Point Four' plan was primarily focused on providing assistance to developing nations, which aligns perfectly with the correct answer. This initiative, announced in his inaugural address in 1949, aimed to use American knowledge and resources to aid countries in their development. Truman believed that the United States had an obligation to help those countries establish programs for improved education, health, and agriculture, thereby fostering economic growth and stability.

This plan represented an important shift in U.S. foreign policy, emphasizing a commitment to developmental aid rather than just military strategies or economic dominance. By focusing on development, Truman aimed to mitigate poverty and reduce the influence of communism in the post-war world. This broader approach was seen as vital for global peace and prosperity, highlighting the interconnectedness of nations in the modern era.

The other options pertained to different aspects of U.S. foreign policy during the same period but did not encapsulate the essence of the 'Point Four' initiative. While military presence and trade agreements were significant components of foreign policy, they did not specifically address the need for direct assistance to developing nations.
