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 analogous to the foreign minister of other nations 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 Secretary of State is Hillary Clinton.

The officially stated goals of the foreign policy of the United States, as mentioned in the Foreign Policy Agenda of the U.S. Department of State, are "to create a more secure, democratic, and prosperous world for the benefit of the American people and the international community." In addition, the United States House Committee on Foreign Affairs states as some of its jurisdictional goals: "export controls, including nonproliferation of nuclear technology and nuclear hardware; measures to foster commercial intercourse with foreign nations and to safeguard American business abroad; international commodity agreements; international education; and protection of American citizens abroad and expatriation." U.S. foreign policy and foreign aid have been the subject of much debate, praise and criticism both domestically and abroad.

The policies of the United States of America comprise all actions taken by its federal government. The executive branch is the primary entity through which policies are enacted, however the policies are derived from a collection of laws, executive decisions, and legal precedents.

The policies of the United States can be divided according to subject matter. The Almanac of Policy Issues, which provides background information, archived documents, and links to major U.S. public policy issues, organized the public policy of the United States into nine categories. The following lists these categories followed by a few examples of specific, respective policies:

Agricultural policy of the United States is the governing policy for agriculture in the United States and is composed primarily of the periodically-renewed federal U.S. farm bills.

In "A New Agricultural Policy for the United States," authors Dennis Keeney and Long Kemp summarize the agricultural policy of the United States as follows: "Because of its unique geography, weather, history and policies, the United States has an agriculture that has been dominated by production of commodity crops for use in animal, industrial and export enterprises. Over time agricultural policies evolved to support an industrialized, commodity-based agriculture. This evolution resulted in farmers leaving the land with agriculture moving to an industrial structure."

The United States of America (commonly abbreviated to the United States, the U.S., the USA, America, and the States) is a federal constitutional republic comprising fifty states and a federal district. The country is situated mostly in central North America, where its forty-eight contiguous states and Washington, D.C., the capital district, lie between the Pacific and Atlantic Oceans, bordered by Canada to the north and Mexico to the south. The state of Alaska is in the northwest of the continent, with Canada to the east and Russia to the west, across the Bering Strait. The state of Hawaii is an archipelago in the mid-Pacific. The country also possesses several territories in the Pacific and Caribbean.

At 3.79 million square miles (9.83 million km²) and with over 312 million people, the United States is the third or fourth largest country by total area, and the third largest by both land area and population. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The U.S. economy is the world's largest national economy, with an estimated 2011 GDP of $15.1 trillion (22% of nominal global GDP and over 19% of global GDP at purchasing-power parity). Per capita income is the world's sixth-highest.

A country's foreign policy, also called the foreign relations policy, consists of self-interest strategies chosen by the state to safeguard its national interests and to achieve its goals within international relations milieu.^{[citation needed]} The approaches are strategically employed to interact with other countries. In recent times, due to the deepening level of globalization and transnational activities, the states will also have to interact with non-state actors. The aforementioned interaction is evaluated and monitored in attempts to maximize benefits of multilateral international cooperation. Since the national interests are paramount, foreign policies are designed by the government through high-level decision making processes. National interests accomplishment can occur as a result of peaceful cooperation with other nations, or through exploitation. Usually, creating foreign policy is the job of the head of government and the foreign minister (or equivalent). In some countries the legislature also has considerable oversight.

Avram Noam Chomsky (/ˈnoʊm ˈtʃɒmski/; born December 7, 1928) is an American linguist, philosopher,cognitive scientist, historian, and activist. He is an Institute Professor and Professor (Emeritus) in the Department of Linguistics & Philosophy at MIT, where he has worked for over 50 years. Chomsky has been described as the "father of modern linguistics" and a major figure of analytic philosophy. His work has influenced fields such as computer science, mathematics, and psychology.

Ideologically identifying with anarcho-syndicalism and libertarian socialism, Chomsky is known for his critiques of U.S. foreign policy and contemporary capitalism, and he has been described as a prominent cultural figure. His media criticism has included Manufacturing Consent: The Political Economy of the Mass Media (1988), co-written with Edward S. Herman, an analysis articulating the propaganda model theory for examining the media.

According to the Arts and Humanities Citation Index in 1992, Chomsky was cited as a source more often than any other living scholar from 1980 to 1992, and was the eighth most cited source overall. Chomsky is the author of over 100 books. He is credited as the creator or co-creator of the Chomsky hierarchy, the universal grammar theory, and the Chomsky–Schützenberger theorem.
