The TPNW came into force in January 2021, marking a significant departure within the global disarmament regime by advocating for the complete abolition of nuclear weapons. Despite its ambitious goals, the treaty has faced criticism from nuclear weapons states, particularly regarding its suggested lack of international security dimensions. This thesis aims to examine the dual aspects of security and humanitarian concerns within the framework of the TPNW. Using a thematic analysis of documents from the TPNW framework, the research investigates how the treaty’s humanitarian and security-driven sides could contribute to fostering a security culture centered around human security. Drawing upon Mary Kaldor’s definition of the two security cultures liberal peace and geo-politics, the thesis explores how the TPNW could be part of shaping a security culture centered around human security and concludes that the Treaty has the potential to foster such international security culture.
