Political realism in international relations is defined by the belief that states primarily act in their own self-interest, prioritizing national power and security over ideals or morality. This perspective emphasizes the anarchic nature of the international system, where no overarching authority exists to enforce order. Political realists argue that moral considerations should take a backseat to strategic calculations, shaping foreign policy and diplomacy. As a result, conflicts, power struggles, and military confrontations are often viewed through a realist lens, highlighting the importance of national interests and the balance of power among states in global affairs.
