Which agency typically convenes interagency meetings for complex issues?

The correct choice indicates that the agency that convenes interagency meetings can vary depending on the specific issue at hand. This reflects the reality of interagency coordination in the U.S. government, where different departments and agencies have differing areas of expertise and jurisdiction.

For complex issues involving national security, foreign policy, economic relations, or domestic policy, the agency responsible for convening discussions will often align with the nature of the issue being addressed. For instance, the National Security Council may take the lead on matters of national security, whereas the Department of State would be more appropriate for diplomatic relations and international treaties. Similarly, other issues might require the involvement of the Department of Defense or other specific agencies based on their relevance to the topic. This approach ensures that the most knowledgeable and appropriate representatives are involved in the discussions for effective decision-making and policy formulation.
