A long-term cause of war refers to underlying factors or conditions that create an environment conducive to conflict over time, such as economic disparities, territorial disputes, or deep-rooted ethnic tensions. In contrast, an immediate cause of war is a specific event or trigger that directly ignites the conflict, such as an assassination, invasion, or declaration of war.
