This article reviews the major arguments regarding the security dilemma in international politics, focusing on its origins, the debates on the cause of the First World War, and nuclear strategic thinking. Special attention will also be paid to the relevance of the security dilemma concept to the emerging issues in the post Cold War era: namely, the problem relating to expanding NATO's membership to Eastern European countries, ethnic conflicts, and the international economic rivalry between the United States and Japan. Although the end of the Cold War appears to reduce the influence of the security dilemma in the Russo-American relations, this article suggests that the security dilemma continues to exist as long as we live in an international system in which no one can take measures to strengthen one's own security without making others feel less secure.
