The relationship of the Weakness of the State in Middle East conflicting regional security complex and insecurity

The middle East over the years after cold war has been encountered various insecure events such as war, separatism, social insurgencies, terror, arms race, security delimma and terrorist groups development and activities.  The evaluation of Middle East changes in the last three decades indicates the "weakness  of the state"  factor as the main cause of emergence of insurgencies. Accordingly, this research by means of explanative- analytic method seeks to answer the question of 'how the impact of the "weakness of  state " of the region ( case studies of Iraq and Syria) causes the appearance  and emergence of Middle East insecurities after cold war'. Findings of the research indicate that the process of nation-state  building in the Middle East has occurred incompletely and this issue besides the weakening of 'States' structure including “idea”, “institution”, “physical bases” in the Middle East, and the intensity of their dysfunctionality in military, political, social, economic and environmental sections, has also caused the decrease of legitimacy and  internally horizontal and vertical conflicts of governments of region. Since foreign policy of states , their way of interaction with each other and territorial security measures are all affected by domestic levels,  and hence internal inability of states in Middle East has paved the way for the formation of conflicting security complex ,great powers intervention and creation of insecurity in the region.
