National identity impacts foreign policy by shaping how a country perceives its role on the global stage, influencing diplomatic relations, trade agreements, and military strategies. A strong national identity can lead to more assertive foreign policies, reflecting a desire to promote national values and interests. Conversely, fragmented identities may contribute to inconsistent foreign policy approaches. Public sentiment shaped by national identity also affects how citizens perceive international issues, impacting domestic political discussions and the electoral landscape. Ultimately, a cohesive national identity fosters a unified approach to foreign relations.
