The invention of Nuclear Technology as epistemological category for the end of the second world war in Far East, has sent shockwaves through the international system. Since then, new military and defence systems were adopted with respect to this power in the Cold War era. The Iranian 1979 revolution, brought a halt to nuclear cooperation which this country had with Germany and France before. Iran halted the construction of Bushehr Facility, and the Iran-Iraq war and few other national security necessities changed the Iran’s discourse in this context. Following this, the Iran Atomic Energy Organization began to fulfil its role effectively again. In this regard, Iran began to make new contracts with Russia.There were few events which cast a shadow over all nuclear activities of Iran and raised doubts about it from United States and European Union points of view. These new perspectives and voices, emphasize that Iran’s discourse in this field, shakes the pillars of international security.The author of this paper has produced a devastating critique of this general debate in the light of challenges over Iran’s fully cooperation with the International Atomic Energy Agency, and specially the European Union/Iran dialogue.
