International relations significantly impact domestic policy by shaping national security, economic strategies, and diplomatic priorities. Policies are often influenced by global trends, alliances, and conflicts, prompting governments to adapt their agendas accordingly. For instance, trade agreements can lead to regulatory changes, while international treaties may require domestic legal reforms. Additionally, public opinion on foreign relations can drive political campaigns, affecting election outcomes and policy direction. As countries navigate the complex landscape of global interactions, the interplay between international relations and domestic policy remains crucial for addressing both global challenges and local needs.
