Context paragraphs:
Conservatism in the United States: American conservatism is a broad system of political beliefs in the United States that is characterized by respect for American traditions, support for Judeo-Christian values, moral absolutism, economic liberalism, anti-communism, American exceptionalism, and a defense of Western culture from the perceived threats of socialization, moral relativism, multiculturalism, and liberal internationalism.

Exceptionalism: Exceptionalism is the perception that a species, country, society, institution, movement, individual, or time period is "exceptional" ("i.e.", unusual or extraordinary) in some way.  Although the idea appears to have developed with respect to an era, today the term is particularly applied to national or regional exceptionalism.  Other uses are rarer in the present day.

Tudjmanism: Tudjmanism (Croatian: "tuđmanizam" ) is a form of Croatian nationalism.  Franjo Tuđman defined it as non-Communist nationalism with "re-examined Croatian history".  According to Croatian historian Ivo Banac, Tudjmanism unites all forms of the Croatian anti-liberalism, that is Croatian fascism and the Croatian communism.  Croatian political scientist Slaven Ravlić defines Tuđmanism to be the name both for an ideology and for a regime.  According to Ravlić, the ideology contains elements of deification of the Croatian people started by Ante Starčević, a continuation of the 20th-century conservative tradition that rejects liberal democracy, and a mix of ideas represented by neoconservatism.  The resulting regime was authoritarian, it created a form of crony capitalism, and engaged in the creation of an ideological hegemony.

Idealism in international relations: Idealism in foreign policy holds that a state should make its internal political philosophy the goal of its foreign policy.  For example, an idealist might believe that ending poverty at home should be coupled with tackling poverty abroad.  U.S. President Woodrow Wilson was an early advocate of idealism.  Wilson's idealism was a precursor to liberal international relations theory, which would arise amongst the "institution-builders" after World War II.  It particularly emphasized the ideal of American exceptionalism.

In addition to working as the 48th president of the APSA Pendleton Herring also served as secretary of Graduate education for Public Administration at Harvard.  Pendleton's scholarly works had a large impact on American political science and also influenced the American government acting as chief intellectual architect of the National Security Act of 1947, which culminated in the reorganization of the military and intelligence branches of the federal government including the creation of the Department of Defense and the Central Intelligence Agency.

American way: The American way of life or simply the American way is the unique lifestyle of the people of the United States of America.  It refers to a nationalist ethos that adheres to the principle of life, liberty and the pursuit of happiness.  At the center of the American way is the American Dream that upward mobility is achievable by any American through hard work.  This concept is intertwined with the concept of American exceptionalism, the belief in the unique culture of the nation.

American exceptionalism: American exceptionalism is an ideology that holds that the United States is unique among nations in a positive way, particularly with respect to its ideals of democracy and personal freedom.

Neo-libertarianism: Neo-libertarianism is a political and social philosophy that is a combination of libertarian principles with present-day neoconservative principles.  This political philosophy prioritizes liberty as its main idea, promoting free expression, freedom of choice, other social freedoms, and "laissez-faire" capitalism, while also being critical of authority.  However, neo-libertarians differ with libertarians on issues of government oversight, as many neo-libertarians tend to sympathize with neoconservative ideas on authority, especially when it comes to military action.  American neo-libertarians believe in the idea of American exceptionalism, and support interventionist policy as a way to maintain America's importance in foreign relations.
