patriot
A person who loves, supports, and defends ones country.
However, a patriot does not necessarily support their leaders actions or a nations policies. For example, the colonists who rebelled against British control during the American Revolution also called themselves patriots when they declared the United States of America an independent nation on July 4, 1776.
Because of this history, the term also has a uniquely American meaning which is embedded in the reverence for the principles established in the Declaration of Independence.
