International Alliances and Regional Blocs: A Conceptual Analysis and their Impact on the Balance of Power in the Contemporary International System

Abstract

The aim of this study is to analyze the theoretical concepts of “international alliances and blocs”, an academic and legal lens by using a critical analysis of the literature in international relations, such as Hans Morgenthau and Ken Booth. Reviewing historical models such as NATO and the BRICS bloc. This analytical framework provides an understanding of the dynamics of alliances and blocs amid the complexities of the contemporary international system. Findings reveal that alliances are often temporary and linked to specific security contexts, whereas blocs tend to exhibit greater continuity, driven by long-term development interests.
