This article intends to go beyond the consequentialist utilitarian approaches to forcible regime change by addressing the question of forcing democracy-building from an angle of appropriateness. It aims to analyze the admissibility of pro-democratic military interventions in international society by focusing on the UN and state practice. Is military intervention to remove a tyrannical regime permissible in international law? To what extend does international society condone an outside force to impose a democratic regime? Does the practice of the UN Security Council in promotion of democracy by force point to an emerging norm with regards to expansive concept of humanitarian intervention? To analyze such questions, this article first provides for a discussion of the concept of intervention. Second, it overviews the normative framework of the use of force in international relations. It continues with the analysis of unilateral and multilateral pro-democratic military interventions, and the UN Security Council practice of condemning, authorizing or consequently endorsing democratic regime change in the target states. In the conclusion part, the article assesses the legality and legitimacy issue regarding the pro-democratic intervention and regime change in light of main norms enshrined in the UN Charter and in general international law.
