This study with assuming complexity situation in the international system, tries to investigate the principles and basis of hegemony strategy in complex regions and the Middle East explained as a case study. The result of the present study explained, that the complexity situation, classical foreign policy strategies based on centrality of control has made incapable of responding to complex threats and new strategies based on condition management imposed to actors of international system and the hegemon is trying to take advantage of these strategies in the regions. Thus, with the complexity of existing system and phenomena in the Middle East, the hegemonic control management approach with the control systems based on the conditions of phenomena and strategic multiplicity and tactical diversity of phenomena management has replaced the hegemonic control centrality and top-down control approach, and hegemon uses of these strategies in its complex deterrence system in the Middle East.
