Over the years the nuclear program of Iran and evolution of events related to it has been the focus of international attention which in turn, transformed it into the most important challenge in the foreign policy activities of the Islamic Republic of Iran as well as providing the grounds for an effective role for The European Union and other powers such as the United States and the Russian Federation. The crisis caused as a result of these international policies has been in did a challenge to the East-West relations in the entire decade of 2000. The role that Russia plaid in this crisis has been of particular interest to the onlookers. To some of these onlookers, Russia had from the start adopted a role in this crisis which has basically concentrated on enhancing its own perceived self interest; while coordinating efforts with the West pretended that it supported Iran’s position. This enabled Russia to maximize its interests in relations with the IRI. But when it came to it, Russia’s support for Iran evaporated and replaced sometimes even by cautioning Iran in the way that satisfied Western friends. All along Russia displayed a position of advocacy for Iran and her rights to Nuclear energy as well as opposing military action against her. This situation resulted in adaption of a vague and unclear position vis-a-vis Washington’s decisive and clearly policies of confrontation against Iran’s nuclear energy program. The result of this vague and unclear standpoint in Russia’s position has been prolongation of the crisis itself. This research will is designed to answer the question that whether Russia’s adaption of vague policy stance and use of delay tactic has been a factor that prolonged the Iranian nuclear energy crisis? The results from this research prove this. The method used for this research is use of library and document centres; benefiting from opinion polls and statistics as well as expertise broadcast in the media and information network.The research hypothesis: this research has followed the hypothesis that based on the information processed herein Russia’s delay tactic and prolongation of Iranian nuclear energy crisis is in keeping with that power’s overall geopolitical competition both with the West globally and with Iran at a regional level.
