The Modern World War had a significant impact that changed the global geopolitical landscape. Geopolitical aspects in this context include conflicts between major countries, changes in alliances, and the creation of new powers on the international stage. One of the main factors causing modern conflict is competition for natural resources, such as oil, water and minerals. The Middle East region, for example, has become the center of attention because of its abundant energy wealth, creating tensions between large countries such as the United States, Russia and OPEC member countries. In addition, the emergence of sophisticated military technology adds to the complexity of modern warfare. Drones and artificial intelligence-based weapons systems enable more efficient military operations but also raise ethical challenges regarding the use of force. Competition in the development of this technology also contributes to tensions between world powers, especially between the US and China in the fields of AI and cyber. Modern geopolitics is also characterized by military actions that often do not involve formal declarations of war. For example, the conflicts in Syria and Ukraine show how military intervention can occur under various justifications, such as the protection of human rights or support for a legitimate government. This creates complexity in international relations, because countries often face a dilemma between national interests and international norms. Cyber ​​warfare is becoming a new arena in geopolitical conflict. His country engages in cyberattacks to support their strategic interests, damage infrastructure, and influence public opinion. For example, digital interference in elections in various countries shows how technology can be used to undermine political stability. The impact of modern war stretches far beyond areas of conflict. Waves of refugee migration due to war influence social and political dynamics in other countries. Europe, for example, faces challenges in dealing with refugees fleeing conflicts in the Middle East and Africa. This creates tension in society, and triggers the rise of populism and nationalism. The continuation of the conflict also has an impact on the global economy. Uncertainty resulting from war and political tensions can shake markets, affect foreign investment, and change trade routes. Dependence on energy from conflict areas makes the global economy highly vulnerable to shocks. Modern conflict resolution is now increasingly complex because it involves many non-state actors, such as terrorist organizations and militias. This complicates the way countries respond, because conventional challenges must be faced together with strengthening international cooperation. Overall, modern world wars brought major changes to the geopolitical structure, affecting security, economics, and social stability on a global scale. As an ever-evolving challenge, this war requires a multidimensional approach involving diplomacy, responsive foreign policy, and collaborative efforts from the international community to achieve sustainable peace.
