The role of international law in humanitarian interventions is to provide a legal framework guiding state actions in responding to crises involving human rights violations. This includes principles from treaties such as the Responsibility to Protect (R2P), which asserts that states have a duty to protect their populations from genocide, war crimes, and crimes against humanity. International law can legitimize interventions by providing a basis for military action or humanitarian aid. However, its effectiveness often depends on political will and the consensus of global powers, raising questions about sovereignty and the ethics of intervention.
