Modern World Warfare has seen significant transformations in military methods and strategies. This evolution reflects technological advances, geopolitical changes, and complex social dynamics. Innovations in weapons and tactics have shaped the way countries wage war. In this context, it is important to understand the periodization and strategies that emerged in the modern era. One of the major turning points in military strategy was World War I. This conflict marked the transition from traditional tactics to trench warfare, where technology such as machine guns and heavy artillery influenced fighting styles. The integration of radio communications allows the command to coordinate attacks more efficiently, changing the way the military operates in the field. As World War II continued, military strategies became more diverse. Germany’s use of Blitzkrieg tactics demonstrated the importance of mobility and speed in attacks. Not only that, amphibious operations such as the D-Day attack on Normandy demonstrated the important role of the navy in supporting land operations. This war also introduced aerial reconnaissance and the use of fighter aircraft as a means of space domination. In the Cold War era, military strategy was based on detente and nuclear deterrence. Military action tended to be shaped by the MAD (Mutually Assured Destruction) doctrine, in which major powers, especially the US and the Soviet Union, focused on developing nuclear weapons to deter enemy attack. These conflicts have also seen the increased use of proxy warfare, in which major powers attempt to influence smaller states without directly engaging in the conflict. Entering the new millennium, military strategy shifted again. With the rise of International Terrorism, countries began to adapt to asymmetric warfare tactics. The attacks of September 11, 2001 changed the global security paradigm, forcing countries to focus on intelligence and counter-terrorism operations. The invasions of Afghanistan and Iraq saw the rise of complex non-state conflicts, with militias and terrorist organizations as key actors. Cyber technology is also changing modern military strategy. Cybersecurity is now an important domain in national defense. Cyberattacks can bring down critical infrastructure without the need for physical force. Tensions between countries in cyber warfare show the need for new strategies to deal with unconventional threats. Current military strategies increasingly rely on artificial intelligence (AI) and drones, changing the way operations are conducted on the battlefield. With the ability to collect and analyze data in real time, this technology increases the effectiveness and efficiency of military strategy. The use of drones in reconnaissance and precision strikes shows how technology can be used to reduce civilian casualties and increase accuracy. Civilian involvement in war is also a modern strategic challenge. Wars now involve local populations, with military powers having to consider the social and political impacts of their actions. The concept of “Victory through Hearts and Minds” becomes important in peace and stability missions. In the face of these changes, military experts continue to formulate new theories to guide future strategy. A focus on interoperability between armed forces and the use of modern tools can ensure readiness to face threats in an ever-changing era. Overall, the evolution of military strategy in Modern World War is a reflection of adaptive learning, where social, political and technological changes influence each other to create a new paradigm in warfare. Strategies that worked in the past may no longer be relevant, demanding continued innovation in the way countries prepare and carry out military operations.
