This war started with the Israeli attack on Iran involving complex military intelligence and political operations. It clarified the limits of traditional security methods. We now know that things other than military strength matter for national security. The war revealed how vulnerable countries are when faced with non-physical threats. These hazardous threats can infiltrate our systems, disrupt our information networks, and even cause a schism in our society. This research paper examines the aforementioned events using Realism, Liberalism, Critical Security Studies, and Human Security, all tools that can help us understand modern conflict better. These debates about the shrinking demarcation between state and non-state actors, the growing role of private corporations in espionage and cyber warfare, changing nature of international partnerships, and the necessity of a nation to be strong and united. As per the report, to have actual national security in the 21st century, we should not limit ourselves to military defence only. It needs a bigger plan that provides solid cyber intelligence, credible information warfare, strong community ties, and efforts at technological independence. This way of doing things is not only smart, it’s necessary. Vulnerabilities in modern systems can spread quickly and a flaw that occurs in one part of security rarely stays in that area. Most of the time, security flaws quickly travel from one area to the other, making the whole security weak. A large cyber-attack, for example, can damage trust and halt economic activity quite rapidly, meaning that the stability of a state can be affected from within. The close relationship necessitates a security policy that harmonizes and coordinates the efforts of all governmental and social branches. Lawmakers should eliminate departmental barriers and create policies that recognize and respond to these connections. A disunited people or an inadequate digital infrastructure cannot be compensated by even a mighty military, they should realize. The objective of this study is to generate a better and more robust definition of national security, drawing important lessons from this conflict. This will contribute to the development of a framework for adaptable and successful governance in a world full of uncertainties.}, number={6}, publisher={Ahmet FİDAN}
