International law influences national security policies by establishing frameworks that govern state conduct, human rights, and conflict resolution. Nations often adhere to international treaties and agreements to maintain peace and security, which can affect their military strategies and diplomatic relations. Compliance with international norms signals commitment to global stability, while deviations may lead to isolation or sanctions. Additionally, national security policies must navigate the complexities of respecting human rights as prescribed by international law, balancing state interests with obligations to uphold justice and humanitarian principles.
