Why do realists so much emphasis on the security?

Realists emphasize security because they view the international system as anarchic, where states must prioritize their survival and sovereignty. In this context, security is paramount, as states face constant threats from other nations and non-state actors. Realists argue that military power and strategic alliances are essential for maintaining security, as the pursuit of national interests often leads to conflict. Ultimately, for realists, the quest for security shapes state behavior and international relations.
