When a country gets power by taking over territory?

When a country gains power by taking over territory, it often involves military force or coercive diplomacy, resulting in a change of sovereignty. This process can lead to significant geopolitical shifts, affecting international relations and regional stability. The annexation of territory may also lead to resistance from the affected population and condemnation from the global community, potentially resulting in sanctions or conflicts. Additionally, such actions can raise complex legal and ethical questions regarding self-determination and international law.
