Assassinating a Head of State Corrodes the System That Makes Diplomacy Possible

The deliberate assassination of a legally recognized head of state (as distinct from killing non‑state militants) damages the normative fabric that lets sovereign states coexist, making future diplomacy, reciprocal legal restraints, and international order harder to sustain. When powerful states or their proxies normalize 'targeted killings' of heads of state, they shift incentives toward escalation, revenge assassinations, and the erosion of restraint across regions. — If adopted as a practice, such strikes change how states perceive sovereignty and retaliation, raising the risk of reciprocal extrajudicial reprisals and a broader breakdown in interstate norms.
