Treaties and international agreements significantly impact national politics by establishing binding commitments between countries on issues such as trade, environmental protection, and security. These agreements can shape domestic policies, requiring nations to align their laws with international standards, often leading to legislative changes or regulatory reforms. Additionally, they can influence public opinion and political discourse, as nations negotiate their interests within a global context. Failure to comply with treaty obligations may incur diplomatic consequences, affecting a country's international standing and its relationships with allies and adversaries.
