This monograph is another in the series of papers from the conference entitled ÒThe U.S. and Russia: Regional Security Issues and Interests,Ó conducted sponsored jointly by the Strategic Studies Institute (SSI) of the U.S. Army War College; the Ellison Center for Russian, East European, and Central Asian Studies at the Jackson School of International Studies at the University of Washington; the Pacific Northwest National LaboratoryÕs Pacific Northwest Center for Global Studies; and Dr. Robert FreedmanÕs monograph analyzes the Russo-Iranian relationship through the spring of 2006. This issue, of course, is vitally important in U.S. foreign policy, not just as it relates to Iran and the overall issue of nonproliferation, especially in the Middle East, but also as U.S. foreign policy pertains to relations with Moscow.
