Modern World War includes various conflicts that have occurred since the end of the 20th century until the present, which directly affect the global order. In the analysis of contemporary conflicts, several main themes that emerge include: geopolitics, economic factors, and social impacts. Geopolitics today is determined by major powers such as the United States, Russia, and China. These three countries are involved in strategic competition which continues to heat up, both in the Asia-Pacific region and Eastern Europe. For example, the conflict in Ukraine that began in 2014 demonstrated tensions between Russia and NATO, which created uncertainty across Europe. On the other hand, the South China Sea has become the focus of tensions between China and ASEAN countries supported by the US, creating the risk of military confrontation. Economic factors are another driver in this conflict. Economic sanctions imposed on countries involved in conflict, such as Russia over Ukraine, show that the economy can be a key tool in modern war. Apart from that, competition for access to natural resources, such as oil and natural gas, has also triggered conflicts in various parts of the world, including in the Middle East and Africa. The social impact of modern war is quite significant. Refugees resulting from armed conflict, as seen in Syria, are a global humanitarian problem. European countries face challenges in handling refugee crises, which often give rise to social tensions within their countries. In addition, propaganda and disinformation in the digital era worsen the situation, creating polarization in society. Advanced military technology also plays a role in contemporary conflicts. Drone weapons, cyber warfare, and cyber defense systems are becoming important components of modern military strategy. Countries are now investing in these technologies, creating new arms races that are more complex than traditional conflicts. Ideological aspects, including extremism and international terrorism, are also part of modern world war. Groups such as ISIS and Al-Qaeda exploit social and economic discontent to recruit followers, and launch terrorist attacks that claim thousands of lives and create global fear. Climate change and its impact on security are also increasingly becoming a concern in the analysis of modern warfare. Depletion of resources such as clean water and food due to climate change can trigger conflicts between countries. For example, tensions in Sudan and the Sahel region caused by climate shifts are exacerbating competition over increasingly scarce resources. The Pentagon and other defense agencies have recognized that future conflicts will involve a combination of conventional and unconventional, making it necessary for stakeholders to adapt. Diplomatic, economic and social approaches are increasingly important in preventing and resolving growing conflicts. Modern world wars are a reflection of complex global dynamics. Viewed from this perspective, it is important for countries to collaborate in finding solutions to ease tensions and build a safer world.
