    • Changing international borders can have significant implications for geopolitical stability as they may alter the balance of power among states. For instance, when a country loses territory, it might face internal unrest or external aggression from neighboring states seeking to exploit the situation.

Understanding these dynamics is crucial for policymakers aiming to maintain peace and cooperation in regions with fluid border situations.
