This paper investigates the roots of Iranian foreign policy toward Iraq and Syria after the 2003 invasion of Iraq. Because of its geo-strategic location, political-cultural characteristics and energy sources, Iran is a pivotal state in shaping the international politics of the Middle East. Since the September 11th events, Iran has increasingly had impact on the issues such as regional crises in Afghanistan, Iraq and Lebanon as well as the war against global terrorism, which are currently the most signi fi cant agenda items of international security. The author argues that Iran’s foreign policy towards Iraq and Syria is primarily geopolitical, oriented at building a secure environment at its borders, for strategic-pragmatic purposes.
