American exceptionalism is the belief that the United States is inherently different from other nations due to its unique history, political system, and cultural values. This idea suggests that America has a special role in promoting democracy, freedom, and individual rights, often viewing itself as a model for other countries. The concept has roots in the founding principles of the nation, including the Declaration of Independence and the Constitution. Proponents argue that these documents reflect a commitment to liberty and equality, while critics contend that this belief can lead to a disregard for global perspectives and responsibilities.
