Isolationism

The Monroe Doctrine in 1823 was largely an expression of the post-1812 nationalism energizing the United States. Although directed at a specific menace in 1823, and hence a kind of period piece, the doctrine proved to be the most famous of all of the long-lived offspring of that nationalism. While giving voice to a spirit of patriotism , it simultaneously deepened the illusion of isolationism. Isolationism is the policy or doctrine of isolating one's country from the affairs of other nations by declining to enter alliances , foreign economic commitments, and international agreements. Isolationism is also seeking to devote the effort on one's country for advancement and remain at peace by avoiding foreign entanglements and responsibilities. But the Monroe Doctrine simply warned the old world powers to stay away.
