As of September 2011, the United States was involved, at different levels, in military operations in Afghanistan, Iraq, Libya, Yemen and Somalia. America has more than 700 military installations overseas, and its military expenses account for almost half of the world’s total . This substantial foreign engagement directly contradicts the United States’ self-professed isolationism in foreign policy. The concept of US isolationism dates back to the colonial days. Evidence for example can be found in Thomas Paine’s work, Common Sense (1776). It was then often reiterated by US leaders, such as Thomas Jefferson and John Quincy Adams, not long after America had gained its independence. Nowadays, characterizations of US foreign policy as isolationist are even further complicated if one moves beyond the field of military intervention and considers the thick web of economic, political, and cultural international relations existing among states. But what about past American foreign policy? Is it sensible to describe it as isolationist? This article analyzes US foreign policy rhetoric to suggest an answer to this inquiry.
