Which US Code establishes interaction between the Department of State and the DOD?

• A. Title 10
• B. Title 22
• C. Title 32
• D. Title 50

Answer: (B)

The interaction between the Department of State and the Department of Defense is rooted in the foreign relations framework of the U.S. Code, which is established to govern diplomacy and how executive agencies work together on international policy. This is codified in Title 22, Foreign Relations and Intercourse, which sets up the statutory basis for diplomacy, international programs, and the coordination of policy across agencies like DoS and DoD. In practice, DoS handles the diplomatic aspects while DoD supports US interests abroad through security cooperation, defense attaché coordination, and joint planning within the foreign policy process, all within the framework created by this title.

Other titles focus on different realms: Title 10 covers the organization and operations of the armed forces themselves rather than interagency diplomacy; Title 32 addresses the National Guard when operating under state control; and Title 50 deals with war and national defense, including overarching defense and intelligence authorities. None of these establish the same interagency diplomacy framework that Title 22 does, which is why Title 22 is the right reference for how DoS and DoD interact.
