An excerpt from my latest post at United Liberty:
Libertarians are often accused of being isolationists who are unconcerned about the people of other nations. While it may be true that some libertarians are isolationists, most are non-interventionists — and the two words are not synonymous. Isolationism advocates complete disengagement from foreign affairs. Non-interventionism, on the other hand, embraces engagement with the rest of the world but rejects costly and counterproductive economic, diplomatic, and military coercion.
Thomas Jefferson summed up non-interventionism when he argued for “[p]eace, commerce, and honest friendship with all nations — entangling alliances with none.” These key components of non-interventionism are vital to the health of a free nation. Non-interventionism avoids the fiscal burdens of war and global policing as well as the collectivism that militarization so often inspires. But the components of non-interventionism enunciated by Jefferson also comprise a recipe for promoting liberty, democracy, peace, and stability abroad.
