Passage: The diplomatic history of the United States oscillated among three positions: isolation from diplomatic entanglements of other  nations ; alliances with European and other military partners; and unilateralism, or operating on its own sovereign policy decisions. The US always was large in terms of area, but its population was small, only 4 million in 1790.
