The Middle East today can be considered an area with the features of chaos due to its geopolitical structure, complex historical identity and decades of crisis. In this volatile area, security has undergone an extensive alteration, and the Islamic Republic of Iran, as a major actor and historical activist, needs certain behavioral patterns to correspond to the situations and trends of security chaos. The present paper seeks to identify the elements of Iran's regional behavioral patterns in the Middle East security chaos. It is hypothesized that Iran needs to take advantage of patterns of constructive interaction, balancing, geopolitical stability, and Interactive Order-Building to play a regional role in this chaos. A descriptive-analytical method and theoretical modeling is employed to account for the historical process of chaos in the Middle East and Iran's chaos management model in foreign policy.
