Isolationism is a foreign policy adopted by a nation in which the country refuses to enter into any alliances, foreign trade or economic commitments, or international agreements in hopes of focusing all of its resources into advancement within its own borders while remaining at peace with foreign countries by avoiding all entanglements of foreign agreements.
Non-Interventionism is a foreign policy which holds that political rulers should avoid alliances with other nations, but still retain diplomacy, and avoid all wars not related to direct territorial self-defense. This is based on the grounds that a state should not interfere in the internal politics of another state, based upon the principles of state sovereignty and self-determination. A similar phrase is "strategic independence". Historical examples of supporters of non-interventionism are US Presidents George Washington and Thomas Jefferson, who both favored nonintervention in European Wars while maintaining free trade. Other proponents include United States Senator Robert Taft and United States Congressman Ron Paul.
