I cannot believe that you actually go alone with the term. "American exceptionalism" is the theory that the United States occupies a special niche among the nations of the world[1] in terms of its national credo, historical evolution, political and religious institutions and unique origins. The roots of the belief are attributed to Alexis de Tocqueville,[2][3] who claimed that the then-50-year-old United States held a special place among nations, because it was a country of immigrants and the first modern democracy.American exceptionalism and Manifest Destiny are two sides of the same philosophy. The philosophy says that American people are superior, everybody else in the world is inferior to Americans.
In the old days, empire building was fashionable, just about every country in Europe worth its salt had some form of empire or other. So the philosophy was expressed in terms of building an empire, which was supposed to be the Manifest Destiny of USA.
These days empire building has gone out of fashion, so nobody talks of Manifest Destiny any more. It has morphed into American exceptionalism, which still claims that Americans are superior, other countries are inferior.
This same philosophy was expressed by religious right in religious terms, that God loves USA and Americans more than he loves anybody else.
It is the same philosophy (of superiority of Americans and contempt towards non Americans), but expressed in different ways.
Alexis-Charles-Henri Clérel de Tocqueville (29 July 1805, Paris – 16 April 1859, Cannes) was a French political thinker and historian best known for his Democracy in America (appearing in two volumes: 1835 and 1840) and The Old Regime and the Revolution (1856). In both of these works, he explored the effects of the rising equality of social conditions on the individual and the state in western societies. Democracy in America (1835), his major work, published after his travels in the United States, is today considered an early work of sociology and political science.
An eminent representative of the classical liberal political tradition, Tocqueville was an active participant in French politics, first under the July Monarchy (1830–1848) and then during the Second Republic (1849–1851) which succeeded the February 1848 Revolution. He retired from political life after Louis Napoléon Bonaparte's 2 December 1851 coup, and thereafter began work on The Old Regime and the Revolution, Volume I.
This term was not created by an American and in fact was given to the world by a French historian. The U.S. actually does occupy a special niche among the nations of the world
