Which country is NOT part of the US mutual defense treaties?

The correct answer identifies India as the country that is not included in the United States' mutual defense treaties. The U.S. has established mutual defense agreements with several countries as part of its strategic alliances, particularly in the Asia-Pacific region. These treaties are designed to provide protection and support to the allied nations from aggression or conflict.

The Philippines, South Korea, and Japan all have formal mutual defense treaties with the United States. For instance, the Mutual Defense Treaty with the Philippines dates back to 1951, solidifying U.S. involvement in the region. Similarly, the U.S. entered into a mutual defense pact with South Korea after the Korean War in 1953, ensuring military support if either party is attacked. Additionally, Japan's Treaty of Mutual Cooperation and Security with the U.S. was established in 1960, allowing for mutual defense and cooperation.

In contrast, while India has strengthened military ties and strategic partnerships with the United States in recent years, it does not have a formal mutual defense treaty. This relationship focuses more on trade, military exercises, and intelligence sharing rather than a binding mutual defense agreement.
