International treaties significantly influence national politics by establishing binding agreements between countries that can impact trade, security, and environmental policies. These treaties often require countries to adjust their domestic laws and practices to comply with international standards, enabling cooperation on global issues. For example, treaties can lead to changes in human rights laws or environmental regulations, necessitating adjustments to national legislation. Additionally, countries may leverage treaties to enhance their geopolitical influence, foster diplomatic relations, or address transnational challenges like climate change and global security.
