The interconnectedness of global trade influences international relations. The complexities of this interconnectedness may be better understood through quantitative analysis of the balance of trade within the global economic system. This monograph serves as a proof-of-concept testing analytic tools for better understanding the efficacy and consequences of economic influence in terms of sanctions and other similar macroeconomic regimes. The underlying concept developed is a calculation of economic threat rings describing the propensity and utility of countries to participate in such regimes. Iran is used as a case study as it has a long standing record of sanctions being imposed upon it by the United States and others since its 1979 revolution. Iran continues to be of contemporary interest in American foreign policy owing to concerns with respect to its known sponsorship of terrorism and suspected pursuit of nuclear weapons.
