摘要:In early 2014, Russia Federation annexed Crimea Peninsula from its adjacent Ukraine. In legal dimension, Russia’s aggressive movement was a flagrant violation of international law as Russia used its military preponderance to subjugate the territory of a sovereign state. This study aims to evaluate Russia’s expansionism toward Crimea with searching out political realism’s linkages with conflict. From past to present, realism has always occupied a notable ground in international relations theories. Besides political realism, originated by Hans J. Morgenthau in his masterpiece ‘’Politics Among Nations’’, assesses politics by centering upon interest. Since this study endeavours to show how can political realism be used so as to understand a contentious incident which ended up with Crimea’s annexation to Russia, necessary information is procured with high caution and consistency. To unfold the academic arguments in a well researched and structured way, the authors provide an introduction and explanation of realism and detailed information on political realism of Hans Morgenthau. In addition, both crucial points and connections of Crimea Conflict and political realism are scrutinized and finalized with an appropriate conclusion.
