Does either realism or neo-realism provide a convincing explanation for how states act?

Realism argues that states primarily act out of self-interest and power-seeking behavior, while neo-realism emphasizes the importance of the international system's structure in influencing state behavior. Both theories offer convincing explanations, but their validity may vary depending on the specific context or situation being analyzed. Ultimately, the applicability of realism and neo-realism in explaining state actions remains a subject of debate among scholars.
