The actual carrying out, or implementation, of foreign policy falls to:
1. The president: The President of the United States plays a significant role in the implementation of foreign policy. As the head of state and government, the president has the authority to make decisions regarding foreign relations, negotiate treaties, and interact with foreign leaders on behalf of the country.
2. Executive agencies: Executive agencies, such as the Department of State, Department of Defense, and intelligence agencies, are responsible for executing and carrying out the foreign policy directives set by the president. These agencies play a crucial role in implementing diplomatic initiatives, managing international relations, and overseeing defense and security matters.
Therefore, both the president and executive agencies are key actors in the implementation of foreign policy, each contributing to the execution of strategic decisions and actions on the global stage.
