International diplomacy impacts domestic politics by shaping national policies and public opinion. Diplomatic relations can influence trade agreements, security alliances, and immigration policies, directly affecting citizens' lives. Domestic political leaders often align their agendas with international considerations, using foreign policy successes or failures to bolster their standings. In times of international crisis, politicians may adopt measures that appease public sentiment or nationalistic tendencies. An interconnected world means that external events frequently ripple through domestic structures, thereby altering policy priorities and governance dynamics.
