Which of the following is a key provision of DoD Directive 5530.3 regarding international agreements?

The correct answer focuses on the requirement that requests for authority concerning international agreements must follow a structured process. Specifically, it is crucial that these requests are properly vetted and submitted to Congress to ensure oversight and compliance with legislative frameworks.

This provision underscores the importance of transparency and accountability in foreign affairs and defense-related agreements. By requiring that these requests be directed to Congress, it ensures that there is legislative oversight of agreements that may have significant implications for national security and international relations. This requirement aligns with the broader objectives of ensuring that all international agreements are conducted in a manner that is consistent with U.S. laws and policy objectives.

The other options, while they address various aspects of international agreement protocols and policies, do not accurately reflect the critical requirement outlined in DoD Directive 5530.3 about submission to Congress. They might emphasize non-disclosure policies or approval authority concerns, but these do not capture the essence of legislative oversight mandated by the directive.
