The foreign policy of the United States is the way in which it interacts with foreign nations and sets standards of interaction for its organizations, corporations and individual citizens. The U.S. is highly influential in the world. The global reach of the United States is backed by a $15 trillion economy, approximately a quarter of global GDP, and a defense budget of $711 billion, which accounts for approximately 43% of global military spending. The U.S. Secretary of State is the foreign minister and is the official charged with state-to-state diplomacy, although the president has ultimate authority over foreign policy; that policy includes defining the national interest, as well as the strategies chosen both to safeguard that and to achieve its policy goals. The current foreign minister is Hillary Clinton.
