International law plays a crucial role in mediating state conflicts by establishing rules and frameworks for collaboration and resolution. It guides nations in addressing disputes through diplomatic channels and provides mechanisms, such as treaties and conventions, that promote peaceful coexistence. By defining sovereignty and state responsibilities, international law helps prevent escalation into violence. Additionally, it can facilitate conflict resolution through arbitration and adjudication in international courts. Ultimately, the efficacy of international law depends on the willingness of states to adhere to these principles and cooperate for mutual benefit.
