Targeted Killing Is Losing Its Stigma, and That Should Worry Everyone

There was a time, not so long ago, when the deliberate targeting of an enemy's political or military leadership carried a whiff of the disreputable. Assassination was what rogue states did. Democracies, at least in their public self-presentation, preferred to fight armies rather than murder commanders. That norm was always honored more in the breach than in the observance, but it existed, and its existence mattered. Today, that restraint is dissolving with remarkable speed, and the implications stretch far beyond any single conflict.

The shift has been gradual but unmistakable. Israel's killing of Hezbollah leader Hassan Nasrallah in September 2024, followed by strikes on Hamas's political leadership, marked a new threshold in the open embrace of what military planners call "leadership targeting" or, more bluntly, decapitation strategy. The United States, for its part, normalized the practice after 9/11 with its drone campaign, which killed thousands of individuals specifically selected for elimination. Russia has been accused of targeting Ukrainian commanders and officials. The logic, in each case, is seductive: remove the head, and the body collapses. Wars end faster. Fewer soldiers die.

The problem is that the evidence for this logic is thin, and the costs of normalizing it are compounding in ways that rarely make the front page.

Decapitation strategy rests on a theory of organizational fragility: that movements, armies, and governments are so dependent on individual leaders that removing those leaders causes systemic collapse. Decades of research have largely failed to confirm this. A landmark study by political scientists Bryan Price and others found that while leadership targeting can sometimes shorten the lifespan of terrorist organizations, the effect is inconsistent and often counterproductive. Killing a charismatic leader can martyrize them, harden recruitment, and push organizations toward more decentralized, resilient structures that are harder to defeat.

Hezbollah, for instance, survived the assassination of its founder Abbas al-Musawi in 1992 and emerged stronger. Hamas has reconstituted its leadership repeatedly across decades of Israeli targeting. The Islamic State lost Abu Bakr al-Baghdadi in 2019 and remains a functioning, if diminished, threat. The pattern suggests that decapitation works best against highly centralized, personality-dependent organizations and worst against those with deep ideological roots and distributed command structures. Most serious adversaries fall into the latter category.

Yet the strategy persists and accelerates, driven not by evidence of effectiveness but by political incentives. Leaders who authorize targeted killings can demonstrate action, project strength, and satisfy domestic audiences demanding visible results. The feedback loop here is perverse: when decapitation fails to end a conflict, the response is rarely to question the strategy but to expand it, targeting more people, more broadly defined as legitimate.

The erosion of norms against leadership targeting carries second-order consequences that are easy to underestimate. The most significant is reciprocity. Norms in warfare, like norms in most human systems, function through mutual expectation. When one actor abandons restraint, it licenses others to do the same. States that aggressively pursue the assassination of foreign leaders are implicitly accepting a world in which their own leaders are legitimate targets. This is not a hypothetical: Iranian officials have openly discussed retaliatory targeting of American and Israeli figures, and the logic of equivalence is difficult to argue against once the underlying norm has been discarded.

There is also a bureaucratic and technological dimension that deserves more attention. The infrastructure built to support targeted killing, the surveillance networks, the legal frameworks, the drone fleets, the intelligence pipelines, does not sit idle between campaigns. It expands, finds new applications, and generates institutional pressure for its own continued use. The normalization of decapitation strategy is partly a story about what happens when powerful tools exist and the political cost of using them falls toward zero.

Perhaps the most underappreciated consequence is what this shift does to the broader architecture of international law. The prohibition on assassination was never absolute, but it was a load-bearing norm in the structure of laws of armed conflict. As it weakens, adjacent norms come under pressure too. The boundaries between combatant and civilian, between war and peace, between legitimate military action and state-sponsored murder, become harder to defend. Once a society decides that killing the right person is always preferable to fighting their army, it has made a philosophical commitment with implications it may not have fully considered.

The taboo against targeting leaders was never simply squeamishness. It was, in part, a recognition that wars fought without such limits tend not to end. They metastasize. The leaders who order decapitation strikes rarely ask what kind of world they are building for the leaders who come after them.
