Washington's hope that the United States would end permanent alliances with foreign nations was realized in 1800 with the Convention of 1800, the Treaty of Mortefontaine which officially ended the 1778 Treaty of Alliance, in exchange for ending the Quasi-War and establishing most favored nation trade relations with Napoleonic France.[10] In 1823, Washington's foreign policy goals were further realized in the Monroe Doctrine, which promised non-interference in European affairs so long as the nations of Europe did not seek to colonize or interfere with the newly independent Latin American nations of Central and South America. The United States did not enter into any permanent military alliances with foreign nations until the 1949 North Atlantic Treaty[11] which formed NATO.
