Isolationism

Isolationism is a foreign policy which combines a non-interventionist military policy and a political policy of economic nationalism (protectionism). In other words, it asserts both of the following: 1. Non-interventionism – Political rulers should avoid entangling alliances with other nations and avoid all wars not related to direct territorial self-defense. 2. Protectionism – There should be legal barriers to control trade and cultural exchange with people in other states. Isolationism is not to be confused with the non-interventionist philosophy and foreign policy of the libertarian world view, which espouses unrestricted free trade and freedom of travel for individuals to all countries. This "libertarian isolationist" view is best defined as a policy of non-participation in foreign political relations, but free trade and affability to all people.
