Which US government agency oversees the overall foreign military sales program?

The Defense Security Cooperation Agency (DSCA) is the correct answer because it is the dedicated agency within the Department of Defense that manages and oversees the foreign military sales (FMS) program. DSCA is responsible for administering the policies and procedures related to defense sales to foreign countries, ensuring compliance with U.S. laws and regulations, and providing guidance for effective implementation of these sales. This encompasses everything from the initial solicitation of interest by foreign nations to the final sale and delivery of defense equipment and services.

This role is crucial because foreign military sales not only involve significant financial transactions but also impact national security, foreign policy, and international relationships. DSCA coordinates with various other agencies, including the DoD, to streamline and execute these sales, ensuring that they contribute positively to U.S. strategic interests abroad.

In contrast, while the Department of Defense (DoD) oversees all military operations and policy, it is DSCA that specifically manages the FMS program. The Federal Bureau of Investigation (FBI) and the Central Intelligence Agency (CIA) have entirely different missions related to law enforcement and intelligence, respectively, and do not have oversight or direct involvement in foreign military sales.
