Modern World War: Global Conflict in the Digital Era Modern world war is characterized by unprecedented complexity and dynamics, especially with the emergence of digital technology. The concept of war is no longer limited to physical combat on the battlefield, but has expanded to conflicts involving cyber, information and asymmetric warfare. In this context, war is not only military, but also includes social, economic and political dimensions. One important aspect of modern warfare is the use of information technology. Countries now rely on cyberspace systems to attack enemy vital infrastructure. For example, hacking of electrical systems, water outages, and sensitive data can cause huge losses without having to engage in physical combat. Cyber attacks that have occurred on the health sector and election systems in various countries prove how big the impact of this technology is on national stability. Social media also plays an important role in today’s global conflicts. The rapid spread of information and disinformation can influence public opinion and shape war narratives. Countries with strong digital propaganda capabilities can often manipulate global perceptions, increase political tensions, and fuel social instability in other countries. The most obvious example is Russia’s interference in the 2016 US election, where social media became a tool to influence voters. Modern war has also seen the emergence of non-state actors, such as terrorist groups or paramilitary organizations, who utilize the latest technology for their actions. They use online platforms for recruitment, propaganda and fundraising. The fight against terrorism is becoming increasingly complicated by the existence of groups that are not tied to any particular country, causing new challenges for global security policy. In a geopolitical context, large countries such as the United States, Russia, and China compete for global dominance through technology. The cyber arms race, artificial intelligence and drone technology are key to future military power. Research and development in this field not only aims to improve defensive capabilities, but also to master strategic information that can change the shape of future conflicts. The social aspects of modern warfare should not be ignored either. Globalization and interconnectedness between countries creates a significant domino effect. Refugee crises, the economic impact of sanctions, and climate change often trigger larger conflicts, involving more countries and actors. Mistakes in one area can trigger instability in another, demonstrating that modern warfare requires new approaches to diplomacy and conflict resolution. Modern world war requires countries to adapt quickly to the changes that occur. Security policy can no longer focus on military aspects alone, but needs to involve a multidimensional approach that includes international cooperation, technological development, and understanding the social issues behind the conflict. Thus, learning from previous wars is important for building effective strategies in this digital era. Through a deep understanding of global conflict in the digital era, countries can formulate more effective strategies to overcome new challenges that arise. These efforts require collaboration between governments, the private sector, and civil society to create a more stable and secure world.
