This study critically examines the tension between state sovereignty and external intervention through the lens of the 2026 United States intervention in Venezuela, situating the event within the broader framework of contemporary international law. Traditionally, sovereignty has functioned as a foundational principle safeguarding territorial integrity and political independence, reinforced by the prohibition on the use of force under the United Nations Charter. However, evolving global challenges—including humanitarian crises, transnational threats, and contested governance—have increasingly tested the rigidity of this norm. The 2026 intervention presents a complex case in which legal justifications, including counter-narcotics operations, democratic restoration, and humanitarian considerations, intersect with geopolitical interests. This paper evaluates the legality of the intervention by analyzing its alignment with established exceptions such as self-defense and Security Council authorization, while also interrogating emerging doctrines like the Responsibility to Protect. It further explores the implications of unilateral action for the credibility and consistency of international law, highlighting concerns over selective enforcement and precedent-setting behavior by powerful states. Ultimately, the study argues that the incident underscores an urgent need to recalibrate international legal frameworks to better reconcile sovereignty with evolving norms of intervention, ensuring both the protection of state integrity and the promotion of global stability and human rights.
