cooperation in foreign policy of iran and russia against east-west axis in south caucasus

vacuum of power was one of the most important consequences of ussr collapse. regional and trans-regional countries have been pulled to south caucasus to extend their influence on this region. turkey and israel thought alliance with azerbaijan constitute east-west pivot. this cooperation threatens common interests of russia and iran. reaction of tehran and moscow creates north-south axis thought alliance with armenia and attempts to affect influence of east-west axis. but interaction between tehran and moscow does not seem so sustainable. thus, this question can be raised: what is the nature of iran and russia’s cooperation in south caucasus? what is the level of iran and russia’s foreign policy interaction to deal with the east- west axis? “with the passing of more than two decades of soviet :union: dismantlement, tehran and moscow cooperation has not reached strategic level. regional interactions of iran and russia has defensive nature with tactical function.” this hypothesis will be tested by alliances and coalitions in realism theory.
