International law profoundly impacts national politics by establishing frameworks that govern state behavior and interactions. It sets principles for issues such as human rights, environmental standards, and conflict resolution, influencing domestic legislation and policies. Nations often must align their laws with international agreements to foster cooperation and avoid sanctions. Additionally, international law affects sovereignty, as states may need to cede some decision-making power to comply with global norms. This dynamic reshapes national political landscapes by promoting accountability and encouraging states to adopt more progressive domestic policies.
