What must be true for international agreements involving classified military information?

International agreements involving classified military information must be consistent with NDP-1 guidelines because these guidelines provide a framework for ensuring that all disclosures of classified information to foreign partners are conducted in a manner that protects national security interests. NDP-1, or National Disclosure Policy 1, outlines the responsibilities and processes for disclosing classified military information to foreign nations. When agreements adhere to NDP-1, they ensure that the information is shared in compliance with established protocols and only with nations that present a strategic alliance or diplomatic necessity. This alignment helps maintain the integrity of U.S. classified information while fostering international cooperation where appropriate.

The other options do not reflect the requirements for handling classified information correctly within the context of international agreements. Non-governmental organizations typically do not have the authority to negotiate such agreements; U.S. domestic laws are important but must also consider international obligations and security standards; and disregarding classification guidelines could lead to significant security risks, undermining the intent of classified protections.
