What is the main function of the Department of State?

The main function of the Department of State is to handle foreign affairs and manage diplomatic missions. This department is responsible for shaping the nation's foreign policy, which includes interacting with other countries, representing the U.S. in international organizations, negotiating treaties, and fostering relationships with foreign governments. It plays a crucial role in international diplomacy, advocating for U.S. interests abroad, and addressing global issues such as trade, security, and human rights.

The Department of State also manages the nation's embassies and consulates, ensuring that U.S. citizens abroad have support and that American interests are protected. This central role in diplomacy and international relations distinguishes it from other governmental functions that focus on domestic affairs, defense, or immigration.
