The comparative comparison of the nationalization Of the oil industry and Iran's nuclear File

International system as one unity general which has the independent and distinctive entity from its founding units creates particular- behavioral constraints.The conservative entity of International system makes any changes in the structure and hierarchy of power become more difficult.In particular,big powers in the scale of the system which the structure of International system is shaped according to them, in order to maintain existing conditions and regularity do not allow the emergence of other big powers that will cause structural changes. Having no ideological consistency with International system, countries that pursue revolutionary or revisionist and independent foreign policy will encounter more structural constraints .The nationalization of the oil industry movement and Iran's nuclear energy program also pursue a revisionist strategy in a region and world-wide scale which face structural constraints. In this study,we want to answer this question that what strategy has been pursued vis-à-vis the nationalization of the oil industry and the nuclear file of Iran by important and international actors (united states, Russia and Britain)?We assume that Iran persist a revisionist strategy in the nationalizati on of the oil industry movement and nuclear energy program that face the disapproval of West and structural constraints.The main-strategy of these three big powers is disapproval of the nationalization of the oil industry and reaching of Iran to nuclear energy, in a way that big powers severely oppose them
