These shared standards of right and wrong guide conduct among states, international organizations, and other global actors, influencing policies on issues like human rights, war, and diplomacy. The study of ethical norms in IR draws from various theories and historical events. It examines key debates like state sovereignty versus human rights, and explores practical applications in areas such as foreign policy, international law, and global governance. Understanding these norms is crucial for navigating complex global challenges.
