The Heartbeat of Unity: Exploring Solidarity in the Trans-Atlantic, Asia, and Muslim World

This study analyzes how states express solidarity within international organizations, focusing on the Transatlantic Community, Organization of Islamic Countries, and ASEAN. Using the English School framework, we examine UNGA speeches (1991–2022) from these groupings, employing sentiment analysis and topic modeling to uncover thematic patterns in their narratives of solidarity. Our findings reveal distinct approaches to solidarity within each organization, despite shared participation in global dialogues. States prioritize different issues and demonstrate active agency in shaping institutional evolution through their discourse. This micro-perspective contributes to the understanding of solidarity-plurality, highlighting the complex interplay between state action and institution-building in a multipolar world. The research challenges simplistic views of state behavior within international organizations, demonstrating the importance of analyzing state narratives to understand the diverse expressions and practices of international solidarity.
