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:

Non-interventionism – Political rulers should avoid entangling alliances with other nations and avoid all wars not related to direct territorial self-defense.

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.
