Multiple large studies and historical analyses demonstrate that violence in the political arena often perpetuates a cycle—where acts of political violence, rather than resolving grievances, contribute to further radicalization, retaliation, and instability.
Both theoretical research and empirical data show that violent incidents and destabilized periods (like elections or major protests) can trigger recurring waves or "cycles" of political violence.[1][2][3]
In sum, empirical studies and U.S. history strongly support that violence in politics typically perpetuates further violence—a self-sustaining cycle well-documented in both modern data and over two centuries of historical episodes.[1][2][4][3]
