Final answer:
For guidance on the transmission or transport of foreign government information, refer to DoD Directive 5230.11 and DoDM 5200.01, which offer detailed instructions related to handling FGI within the Department of Defense.
Step-by-step explanation:
If you are seeking guidance on the transmission or transportation of foreign government information (FGI), there are specific directives and memoranda that can be relevant. The DoD Directive 5230.11, which concerns the disclosure of classified military information to foreign governments and international organizations, would be an appropriate reference. Additionally, the DoDM 5200.01, relating to the DoD Information Security Program, provides guidance on the handling of classified information within the Department of Defense, which would include FGI.
When it comes to National Security Decision Memoranda (NSDMs), they often provide guidance on broader strategic objectives rather than specific procedural instructions. Therefore, for detailed policies on the handling and transmission of FGI, the DoD directives would be more appropriate resources. The information you seek may also be influenced by various statutes and executive orders that frame the United States' foreign policy tools and structures, including but not limited to the National Security Act, the Patriot Act, the Homeland Security Act, and the War Powers Resolution. These acts play a role in the establishment and conduct of foreign policy which subsequently influences the handling of FGI.
