Changes in leadership can significantly impact foreign policy by shifting priorities, strategies, and alliances. New leaders may bring different ideologies and goals, which can result in alterations to existing treaties or international relations. For example, a leader focused on nationalism may withdraw from international agreements, while a more globalist leader might pursue bilateral partnerships. Additionally, transitions can create uncertainty for other nations, who must reassess their own strategies in response. Such shifts often reflect broader changes in a nation's perception of its role on the global stage.
