American diplomacy helps foster and protect democratic values abroad, creating a more secure, stable, and prosperous world. 

Democracy is more than a political system. It is a set of fundamental principles—including liberty, equality, human rights, and justice—that apply to all people. Everywhere American diplomats go, they support these principles, even in countries that may not share our values.
