This book offers insight into the motives behind Moscow's behavior in the Persian Gulf (with a specific focus on the GCC member states and Iran), considering Russia's growing role in the Middle East and its desire to protect national interests using a wide range of means. The book explores the drivers and motivations of the Russian foreign policy in the Gulf region, thus, helping the audience to generate informed prognosis about Moscow's moves in this area over the next years. In contrast to most studies of Russia's presence in the region, this book considers the Russian involvement in the Gulf from two standpoints - the Russian and foreign. The idea of the book is to take several key problems of Moscow's presence in the Gulf, each of these to be covered by two authors-Russian and non-Russian scholars, in order to offer the readers alternative visions of Moscow's policies towards Iran and the GCC countries.
