◼ Every nation derives meaning and purpose from some unifying quality—an ethnic character, a common religion, a shared history. The United States is different. America was founded at a particular time, by a particular people, on the basis of particular principles about man, liberty, and constitutional government.... - Matthew Spalding, Ph.D./Heritage Foundation
...America is an exceptional nation, but not because of what it has achieved or accomplished. America is exceptional because, unlike any other nation, it is dedicated to the principles of human liberty, grounded on the truths that all men are created equal and endowed with equal rights. These permanent truths are "applicable to all men and all times," as Abraham Lincoln once said.
America's principles have created a prosperous and just nation unlike any other nation in history. They explain why Americans strongly defend their country, look fondly to their nation's origins, vigilantly assert their political rights and civic responsibilities, and remain convinced of the special meaning of their country and its role of the world. It is because of its principles, not despite them, that America has achieved greatness.
To this day, so many years after the American Revolution, these principles—proclaimed in the Declaration of Independence and promulgated by the United States Constitution—still define America as a nation and a people. Which is why friends of freedom the world over look to the United States not only as an ally against tyrants and despots but also as a powerful beacon to all those who strive to be free.
