Which level of government takes care of foreign affairs?

The federal government is responsible for handling foreign affairs in the United States. This authority is primarily vested in the executive branch, specifically the President, who acts as the Chief Diplomat. The President, along with the Secretary of State and other diplomatic agencies, engages with other countries, negotiates treaties, and represents the nation in international matters.

This centralization of foreign policy responsibilities in the federal government ensures that the nation's external relations are managed in a cohesive and unified manner. Local and state governments lack the authority and resources to engage in international relations, as their jurisdiction is limited to local or regional issues. Similarly, while terms like "international government" may imply some level of global governance, such entities do not function as sovereign authorities capable of managing national foreign affairs. Therefore, the federal government is the appropriate entity for overseeing and conducting the country’s foreign affairs.
