War impacts domestic political systems by shifting public priorities and altering the political landscape. During wartime, governments may centralize power and prioritize military spending, which can limit civil liberties and lead to increased government surveillance. Public opinion often rallies around patriotic sentiments, affecting electoral outcomes and political support for leaders. Additionally, post-war contexts may bring about new social movements, demands for reconstruction, and changes in governance. The aftermath can also shape foreign policies and national identities as societies grapple with issues related to veterans, peacebuilding, and reconciliation.
