Trust has played a key role since the emergence of international relations. At the same time, international security is associated with public trust. This contribution explores the link between trust and security by examining the UN Security Council resolutions on unlawful destruction of cultural heritage, with the aim to investigate the trustworthiness of this body in exercising its normative power. While cooperation is necessary to address global challenges, distrust on the UN system is growing: the policy-making process no longer seems to be appropriate to the new geopolitical balances in which it is more difficult to balance divergent interests. How can the UN Security Council be restructured to be more trustworthy?Can cooperation on cultural heritage be a bridge between trust and international security? How can cultural heritage policy enhance public trust building and what is the role of States? Can cultural heritage policy be a model to face other global challenges?
