    Realism is a dominant theory in IR that views war as an inevitable feature of the international system, driven by the anarchic nature of global politics, where no central authority exists to enforce rules.

    • Anarchic System: Realists argue that the lack of a central governing body at the international level forces states to rely on their own capabilities for security. This leads to competition, distrust, and sometimes war. The Cold War between the U.S. and the Soviet Union is a prime example of how an anarchic system fosters conflict, as both superpowers sought to outmaneuver each other in a bid for global dominance.
    • Security Dilemma: The security dilemma is a key concept in realism, where one state's efforts to enhance its security (such as building up its military) are seen as a threat by others, prompting an arms race. This was evident during the Cuban Missile Crisis, where U.S. security measures led the Soviet Union to deploy missiles in Cuba, escalating tensions.
    • Power and Survival: Realism holds that states are primarily motivated by the desire to maintain or increase their power to ensure survival. War becomes a tool for this when diplomacy fails. The U.S. invasion of Iraq in 2003 can be viewed through a realist lens as an attempt to secure American interests in the Middle East by eliminating a potential threat.
