International law can significantly impact domestic policy by establishing legal norms and obligations that countries must adhere to. Treaties, conventions, and court rulings influence national legislation and can compel governments to change laws to comply with international standards. For example, agreements on human rights or environmental protections often lead to legislative reforms. However, the extent of this impact varies, depending on a country’s willingness to accept and implement international obligations. Ultimately, the intersection of international law and domestic policy reflects a state’s commitment to global governance and its role within the international community.
