Regime changes can significantly impact international relations by altering alliances, policies, and priorities. New governments may reassess diplomatic ties based on their ideologies, shifting the balance of power in various regions. A change in leadership can lead to realignment in trade agreements, security partnerships, and foreign aid. Additionally, regime changes often provoke instability in the short term, affecting global markets and fostering uncertainty. The resulting geopolitical landscape can pose both challenges and opportunities for diplomatic engagement.
