This article focuses on the tension between the Islamic Middle East and the international community.After a brief study from the political,economic and cultural perspectives and a review of relevant documents and materials,the author has decided on the current research perspective.The sub-state actors in the Middle East mainly refer to religious and political organizations which can infiltrate into or influence this area or the international community,terrorist organizations of religious extremists,straddling groups and minority groups which seek independence or unification.Their major influence on the international community lies in their resistance against the present state weakens the nation state system in the Middle East and pushes anti-state/system movements;their significant role imposes a deep impact on the peace process in the Middle East;they lead to external intervention from the international system and growing tension between the Middle East and the international community.The root of the above-mentioned tension is that the combined actions of internal and external factors have made the Middle East system vulnerable and infiltrable,creating the soil for the rise of religious and political organizations and thus inspiring the anti-system movements of the sub-state actors in the Middle East. 展开更多
