National identity shapes foreign policy by influencing how a country perceives its role on the global stage and its relationships with other nations. Shared values, cultural heritage, and historical experiences inform national interests and priorities, guiding diplomatic strategies and international engagement. Nations with cohesive identities may pursue assertive foreign policies that reflect collective aspirations, while multicultural societies might adopt more inclusive approaches to foreign relations. Ultimately, national identity affects decision-making concerning alliances, trade agreements, and conflict resolution, playing a critical role in defining a nation's global standing and influence.
