"Isolationist" is a pejorative term coined by imperialists and progressives to impugn conservatives who advocated for a humble foreign policy in the late 19th and early 20th centuries. Ending militarism and foreign intervention in lieu of opening trade with all nations who wish to trade with us is not "isolationism". Isolation would be cutting off all contact with the outside world, which non-intervention does not propose. To paraphrase Clyde Wilson, America should "demonstrate democracy, rather than trying to impose it by force." Most of our enemies around the world have been created by a progressive approach to foreign policy.
