National identities significantly influence foreign policy by shaping how countries perceive their role on the global stage. Cultural values, historical experiences, and national interests guide diplomatic strategies and international relations. For instance, nations with strong collective identities may prioritize solidarity with similar countries, leading to regional alliances. Conversely, differing national identities can create tensions and conflicting goals in international negotiations. Thus, understanding how national identity impacts perceptions and priorities is vital for comprehending a country's foreign policy decisions and diplomatic behaviors.
