Political Violence Cycle

4 min read

Definition

The Political Violence Cycle describes the self-reinforcing feedback loop in which acts of political violence — assassinations, attacks on officials, mass shootings at political events — produce radicalization responses that increase the probability of future violence. Each incident is processed asymmetrically by partisan media and political actors, used to justify grievance narratives, and either mourned selectively or celebrated quietly depending on the victim’s political identity. Rather than producing deterrence or de-escalation, political violence in this pattern produces counter-radicalization, threat escalation, and expanded justifications for further violence.

Why It Matters

The U.S. is in an active phase of this cycle. Between 2016 and 2023, there were 21 documented terrorist attacks on public officials motivated by partisan political beliefs — compared to just two in the previous two decades (CSIS data). The Charlie Kirk Assassination in September 2025 followed the June 2025 assassination of a Democratic Minnesota state lawmaker and her husband. The cycle is politically managed rather than interrupted: Trump’s response to Kirk’s death condemned only left-wing rhetoric while omitting attacks on Democrats, which models selective mourning for a national audience.

Evidence & Examples

Tensions & Counterarguments

  • Most Americans in polling say they do not support political violence, suggesting the cycle is driven by a minority that is amplified by partisan media rather than a genuine mass movement toward violence
  • David A. Graham (The Atlantic) warns that the cycle draws government responses that are particularly dangerous when the president “disdains the rule of law” — the cure may accelerate the disease
  • Steven Webster (American Rage) argues both parties’ leaders can break the cycle if they speak consistently — but Trump’s selective response to Kirk showed how easy it is to fail that test
  • The asymmetric treatment of victims (Kirk vs. Hortman) means the cycle may be structurally biased toward right-wing radicalization in the current political environment
