Modern world war is influenced by technological developments and ever-changing strategies. One of the most striking aspects is the use of advanced weapons, such as drones, cyber weapons and air defense systems. Drones, in particular, have revolutionized the way countries conduct surveillance and attacks. With the ability to fly unmanned and collect data in real-time, drones allow the military to maintain control over conflict areas more efficiently. In addition, cyber technology has become a new arena in modern warfare. Large countries such as Russia and China have carried out cyberattacks targeting critical infrastructure in other countries. This includes power outages, disruption to communications networks, and theft of sensitive data. Through investments in research and development, these countries seek to strengthen their cybersecurity and attack opponents in unconventional ways. Missile defense systems have also made significant progress. A clear example is the Aegis and THAAD systems developed by the US. With the ability to detect and intercept ballistic missiles, the system offers better defense against external threats. This changes the dynamics of conflict by providing strategic advantages to host countries. On the other hand, developments in information technology have enabled the militarization of information. Countries use social media and digital platforms for propaganda, influencing public opinion, and creating confusion among adversaries. This strategy has proven effective in preparing the mentality of civilians and soldiers in countries at war. Another aspect worth noting is the concept of “hybrid warfare” in which a combination of conventional and unconventional tactics is used. For example, Russia in the conflict in Ukraine succeeded in implementing this tactic by combining information storytelling, military intervention, and support for separatist groups to achieve strategic goals without engaging in open war directly. Military training and simulations are also important in preparing soldiers to face modern situations. By using augmented and virtual reality, soldiers can train in realistic scenarios, which increases their operational effect in real conflicts. The knowledge and skills gained from this simulation have a significant impact on combat power. In strategic analysis, preemptive strikes and asymmetrical warfare are important topics of debate. The preemptive strike approach prioritizes early attacks to destroy enemy capabilities before the conflict spreads. Meanwhile, asymmetric war refers to a battle between unequal armed forces, where the weaker party uses guerilla tactics to resist the dominance of a stronger opponent. International intelligence exchange also plays a crucial role. Alliances such as NATO and bilateral cooperation involve the exchange of information that improves understanding and reaction to global threats. This collaboration not only involves countries, but also technology companies that provide hardware and software to improve defense capabilities. Finally, an expanding focus on sustained warfare is also increasingly dominating military discussions. In the midst of climate change and a resource crisis, the possibility of resource-related conflicts is very likely. Countries must prepare strategies to address possible tensions arising from competition for access to water, food, and energy.
