Security issues are among the most contested and profound in the study of political science. At the centre of this problem lies on how to save people from a possible danger and threat in the international system and increase the well-being of citizens. Although the solution of the question can be pursued from different political theories, the realistic point of view, in which a state has to protect its citizens from external threats, is the most reliable and also reasonable approach to security dilemma (Nilsson, 2012: 470). This essay, therefore, will mainly deal with the realistic ideas on security dilemma coping with those of liberalistic views. Firstly, it will briefly explain about realist perspective on security dilemma, and the example of Cuban Missile Crisis to support the needlessness of treaties of different nations followed by the inappropriateness of liberal views on collective security (Morgenthau, 2006: 435).
