The role of international law in human rights is to establish a framework that protects individual rights globally. It sets standards through various treaties and conventions, such as the Universal Declaration of Human Rights. International law obligates states to uphold and respect human rights, facilitating accountability for violations. It also serves as a foundation for advocacy and intervention, enabling actions against governments that fail to protect their citizens' rights. By enforcing legal norms, international law promotes universal values and encourages cooperation among nations to improve human rights conditions worldwide.
