The current political fraction between Russia and the West has led to the breakdown of the cooperative post-Cold War security order. Russia’s dramatic reliance on its tactical nuclear weapons arsenal is of concern for how Moscow might shape its foreign policy. Based on the gap in the existing literature on the role of Tactical Nuclear Weapons (TNW) and regional influence, this paper aims to examine the role of TNWs for Russia’s regional influence by answering the following research question: What changes in the nuclear doctrines, with regards to TNWs, contribute to a nuclear state’s increased regional influence? This thesis uses the theoretical frame of Coercive Diplomacy, with focus on compellence, which provides an alternative explanation to one state’s behavior against another in the pursuit of influence. In order to test the hypothesis, offensive changes in the doctrines, with regard to TNWs, contribute to a nuclear state’s likelihood of increasing its regional influence, this qualitative study examines the cases of Georgia and Armenia. The implementation of the analytical framework on the empirical material occurs through the method of structured focused comparison. The findings indicate that despite Russia’s engagement in compellence against Georgia and Armenia, the cases show very different outcomes.
