International treaties can impact national sovereignty by requiring states to adhere to obligations that may limit their unilateral decision-making. Ratifying treaties often means that countries commit to international standards in areas such as human rights, trade, or environmental protection, which can constrain domestic policies. While such agreements can enhance global cooperation and stability, they may provoke debates about the extent to which they infringe upon national autonomy. States must navigate the balance between fulfilling international commitments and maintaining their sovereign rights, often shaping domestic political discourse.
