International treaties can have a profound impact on domestic politics by shaping laws, policies, and political discourse within countries. Treaties, such as those addressing climate change or human rights, often require signatory nations to enact corresponding legislation to fulfill their obligations. This can lead to changes in domestic laws, regulations, and practices that reflect international commitments. Additionally, treaties can influence political debates and party platforms, prompting discussions about national priorities and global responsibilities. The extent of a treaty's influence can vary, depending on public support and political will to comply with international standards.
