This article examines an emerging trend of cross-border conflicts between states and non-state actors. It looks at the narratives fronted by Turkey and Saudi Arabia to justify their operations in northern Syria and Yemen, respectively. The authors argue that the increased inaction and lack of influence by the UN in response to such operations reaffirm states as the core actors in international politics and that national security and interests continue to shape the behavior of actors at the international level. The article concludes that the UN needs to adjust to the new forms of conflicts, actors, and behavior being experienced at the international level if it is to retain its relevance as an anchor of peace and international security.
