The United States has formal diplomatic relations with most nations. This includes all United Nations members and observer states other than Bhutan, Iran and North Korea, and the UN observer Territory of Palestine. Additionally, the U.S. has diplomatic relations with Kosovo and the European Union.
The United States federal statutes relating to foreign relations can be found in Title 22 of the United States Code. The United States has the second-most diplomatic posts of any state, after China.
The United States National Security Council (NSC) is the national security council used by the president of the United States for consideration of national security, military, and foreign policy matters. Based in the White House, it is part of the Executive Office of the President of the United States, and composed of senior national security advisors and Cabinet officials.
Since its inception in 1947 by President Harry S. Truman, the function of the council has been to advise and assist the president on national security and foreign policies. It also serves as the president's principal arm for coordinating these policies among various government agencies. The council has subsequently played a key role in most major events in U.S. foreign policy, from the Korean War to the war on terror.
The United States Department of State (DOS), or simply the State Department, is an executive department of the U.S. federal government responsible for the country's foreign policy and relations. Equivalent to the ministry of foreign affairs of other countries, its primary duties are advising the U.S. president on international relations, administering diplomatic missions, negotiating international treaties and agreements, protecting citizens abroad and representing the U.S. at the United Nations. The department is headquartered in the Harry S Truman Building, a few blocks from the White House, in the Foggy Bottom neighborhood of Washington, D.C.; "Foggy Bottom" is thus sometimes used as a metonym.
Established in 1789 as the first administrative arm of the U.S. executive branch, the State Department is considered among the most powerful and prestigious executive agencies. It is headed by the U.S. secretary of state, who reports directly to the U.S. president and is a member of the Cabinet. Analogous to a foreign minister, the secretary of state serves as the federal government's chief diplomat and representative abroad, and is the first Cabinet official in the order of precedence and in the presidential line of succession. The position is currently held by Marco Rubio, who was appointed by President Donald Trump and confirmed by the U.S. Senate on January 20, 2025, by a vote of 99–0.
National security of the United States is a collective term encompassing the policies of both U.S. national defense and foreign relations.
The Lee Resolution, also known as "The Resolution for Independence", was the formal assertion passed by the Second Continental Congress on July 2, 1776, resolving that the Thirteen Colonies (then referred to as the United Colonies) were "free and independent States" and separate from the British Empire. This created what became the United States, and news of the act was published that evening in The Pennsylvania Evening Post and the following day in The Pennsylvania Gazette. The Declaration of Independence, which officially announced and explained the case for independence, was approved two days later, on July 4, 1776.
The resolution is named for Richard Henry Lee of Virginia, who proposed it to Congress after receiving instructions and wording from the Fifth Virginia Convention and its president, Edmund Pendleton. Lee's full resolution had three parts which were considered by Congress on June 7, 1776. Along with the independence issue, it also proposed to establish a plan for ensuing American foreign relations, and to prepare a plan of a confederation for the states to consider. Congress decided to address each of these three parts separately.
