Long regarded as unthinkable or dishonourable, the targeting of enemy leaders is becoming a standard tactic of war, and the implications go far beyond individual battles. A story often recounted about the Battle of Waterloo illustrates this old moral restraint. A soldier allegedly reported to the Duke of Wellington that Napoleon was in sight and vulnerable to attack. Wellington, according to the tale, refused to authorize the shot, citing the dishonour in targeting a commander directly. While the anecdote may be apocryphal, as biographer Andrew Roberts notes, it reflects centuries-old norms in which leaders were considered off-limits during conflict. Today, such constraints are eroding, particularly in conflicts involving the United States, Israel, and other technologically capable powers.
According to a recent essay in the Financial Times, the explicit targeting of state leaders is becoming increasingly commonplace. The U.S. and Israel, for instance, have openly aimed to neutralize Iran’s top leadership during the latest Middle East war, including Ayatollah Ali Khamenei. Similarly, a U.S. operation to capture Venezuelan President Nicolás Maduro in January shocked the international community. While Maduro was not killed, the raid signalled a willingness to disregard longstanding taboos, reflecting a broader shift toward normalising the “decapitation strike” as a tool of modern geopolitics.
Historically, targeting political leaders was subject to both legal and moral restraints. International law grants leaders a range of immunities in peacetime, and in war, the general laws of armed conflict apply. Veteran U.S. diplomat Philip Zelikow explains that the classification of a leader as an “enemy combatant” is a key determinant, though civilians are otherwise protected. Legal scholars note that there is no absolute prohibition against targeting state leaders per se, but norms, political conventions, and reciprocity historically prevented such acts from being openly celebrated. As Lawrence Freedman, emeritus professor of war studies at King’s College London, observes, the conventional wisdom was that targeting leaders was prohibited “on the grounds that everybody would lose.”
The modern practice of decapitation strikes can be traced through multiple phases. Until the late 20th century, assassination attempts were covert, often carried out through proxies, and condemned if exposed. The Church Committee of the U.S. Senate in 1975 highlighted the moral and political dangers of targeting foreign leaders, prompting executive orders banning such killings under presidents Gerald Ford and Ronald Reagan. Yet even during the Reagan era, attacks on leaders like Muammar Gaddafi blurred these lines, often justified as self-defense or accidental. The U.S.-led decapitation strikes against Saddam Hussein in 2003 further demonstrated the erosion of secrecy surrounding such operations.
In the third phase, beginning with the U.S. killing of Iranian commander Qassem Soleimani in 2020, transparency and spectacle became part of the strategy. Decapitation strikes are now openly discussed and, in some cases, celebrated as a sign of military prowess. The Maduro raid in Venezuela and Israeli strikes against Hezbollah exemplify this shift. Scholars like Luca Trenta argue that the old restraint has disappeared, and with it, the implicit respect for international norms governing state sovereignty. What remains is a practical calculus: does the operation work, and what are its consequences?
There are both pragmatic and ethical arguments for and against decapitation strikes. Supporters contend that removing a leader may disorient the adversary, disrupt command structures, and prevent larger-scale conflicts. Freedman notes that targeting autocratic leaders, whose authority is often centralized, can be particularly effective. Similarly, in situations perceived as existential threats—such as Israel faces—striking a single leader may be viewed as a morally justifiable alternative to full-scale war. Historical analogies, including debates over the atomic bomb in 1945, highlight the utilitarian reasoning behind targeting key figures to reduce broader casualties.
Yet empirical research and historical experience temper these arguments. Decapitation is not always effective, particularly against sophisticated organizations. Jenna Jordan, a scholar of terrorism, observes that targeting leaders of mature terrorist networks may provoke retaliation or mobilize previously passive supporters. Even when effective in the short term, such strikes can create political instability or empower less predictable successors. Trenta notes that decapitation strategies are a common element of counterinsurgency campaigns, often repeated despite uncertain results, highlighting the tension between strategic hope and empirical reality.
Beyond effectiveness, the normalisation of decapitation strikes carries profound implications for international order. The principle that leaders are untouchable underpins the Westphalian system, in which sovereignty is vested in states rather than individuals. When the personal safety of leaders is subordinated to tactical objectives, the distinction between state and ruler collapses, creating what Stacie Goddard and Abraham Newman describe as a “neo-royalist” order. In such a system, the accumulation of power and wealth by ruling elites supersedes national or collective interests, eroding norms of territorial sovereignty and non-intervention.
There are also questions of selective enforcement and historical bias. Decapitation strikes are disproportionately used against leaders in the developing world, raising concerns about racism, imperialism, and the uneven application of international norms. Freedman highlights that historical attempts to assassinate figures like Archduke Franz Ferdinand or early 20th-century anarchists carried destabilizing consequences, demonstrating the risks of breaking taboos. The Financial Times essay suggests that while such operations may achieve short-term tactical gains, the broader cost to international norms and the moral authority of states is significant.
As decapitation strikes become more visible and normalized, the world confronts a stark question: what do we lose when leaders are no longer off-limits? The erosion of restraint in targeting heads of state undermines reciprocity, the foundations of sovereignty, and the international rules designed to maintain global order. While the short-term calculus may favor tactical advantage, the long-term consequences for stability, legitimacy, and moral authority remain uncertain. In the words of Trenta, the practice persists despite mixed results, reflecting both the allure and the danger of a strategy whose ethical and strategic implications are still unfolding.
The shift in norms described by the Financial Times indicates that the taboo against targeting state leaders—a cornerstone of modern warfare and diplomacy—is under unprecedented pressure. Whether this trend leads to a new, more unstable international order or evolves into a more effective form of conflict management, the world is witnessing the transformation of a principle that once shaped the conduct of war and the preservation of sovereignty.
