International relations shape domestic politics by influencing the political environment, policy priorities, and public opinion within a country. Global events, such as conflicts, trade agreements, and alliances, can lead to shifts in national policy agendas and affect how governments address issues like security and economic stability. For example, a country may adjust its immigration policies in response to international crises or change its defense strategy based on shifting diplomatic relationships. Additionally, international organizations and treaties can compel domestic changes, requiring governments to align their laws and practices with global standards or agreements, thereby shaping the political landscape.
