In a current publish on this weblog, Sophie Duroy and Luca Trenta have supplied an essential and well timed evaluation of the normalisation of assassination as a instrument of Statecraft, arguing that the killing of Iranian Supreme Chief Ali Khamenei on 28 February 2026 represents “a brand new stage within the erosion of the worldwide norm in opposition to assassination”. The issues they voice are well-founded. The deliberate concentrating on and killing of a sitting head of State is a worrying precedent.
On this publish, I need to concentrate on one seemingly minor declare that runs via the Duroy and Trenta evaluation: the assertion that Khamenei was killed “exterior an armed battle”.
Splitting hairs once more?
It is very important perceive what activates the query and, equally, what doesn’t. The applicability of the legislation of armed battle to the killing of Khamenei has no bearing on the foundations governing resort to power. These two our bodies of legislation function independently. There isn’t a tenable justification for the US-Israeli assault on Iran below the foundations governing using power, as others have defined (see right here, right here and right here). Even when Khamenei was a army goal and directing an assault in opposition to him was not a violation of the legislation of armed battle (see right here for evaluation), this by no means justifies using power in opposition to Iran below the foundations on using power: his killing would nonetheless kind a part of an act of aggression and due to this fact be illegal below these guidelines.
Then why does the applicability of the legislation of armed battle matter right here? The legislation of armed battle channels violence. It confers numerous protections on sure individuals and objects, equivalent to civilians, the wounded and sick and objects indispensable to the survival of the civilian inhabitants, while additionally tolerating and even allowing using violence in opposition to army aims. As soon as a world armed battle exists, these guidelines apply to all belligerents, no matter whether or not they’re aggressors or victims of aggression. Within the current case, the USA, Israel and another nation utilizing power unlawfully should due to this fact observe the bounds that the legislation of armed battle imposes on the conduct of hostilities. This agnosticism of the legislation of armed battle with regard to the origins of the battle is certainly one of its best property: it isn’t essential to agree about which State is committing acts of aggression and which State is performing in self-defence, as all events to the battle should adjust to the legislation of armed battle, regardless of the reply to these use of power questions is. The boundaries imposed by the legislation of armed battle ought to due to this fact function as an uncontroversial, generally accepted baseline of behaviour amongst all belligerents, even when there may be little or no else that they might agree on.
Whether or not or not the legislation of armed battle utilized to Khamenei’s killing is due to this fact not some technicality that dangers diverting our consideration from the “actual” points. Quite the opposite, it has nice sensible and normative significance.
Is there an armed battle?
It’s useful to start out by asking whether or not an armed battle exists between the US and Israel on the one aspect and Iran on the opposite aspect at this cut-off date. The reply is clearly sure.
A world armed battle exists every time there may be resort to armed power between two or extra States, because the ICTY Appeals Chamber held in Prosecutor v. Tadić (para. 70). Below the prevailing view, no minimal length or stage of depth of preventing is required. Nevertheless, even those that argue for a minimal gravity threshold ought to have little issue classifying the current scenario as a world armed battle. The 28 February strikes alone concerned over 1,500 air and missile assaults in opposition to targets throughout Iran, carried out collectively by US and Israeli forces, whereas Iran responded with ballistic missile strikes in opposition to US army bases throughout the area and in opposition to Israel. Service personnel and civilians had been killed and the fabric harm is in depth. There may be nothing remotely de minimis about this resort to power. Consequently, a world armed battle exists, with none shadow of doubt.
Duroy and Trenta provide no rationalization for his or her assumption that Khamenei’s killing passed off exterior an armed battle. With out wanting to place phrases into their mouths, two arguments come to thoughts that may help their place.
Belligerent nexus
Not each act of violence that takes place throughout an armed battle is essentially an act of hostilities. Pub fights and armed robberies nonetheless occur throughout struggle. In precept, such incidents aren’t ruled by the legislation of armed battle. The primary risk, due to this fact, is that the strike in opposition to Khamenei had no nexus to the continued hostilities. Nevertheless, this argument might be discounted rapidly. In an official assertion, the Israel Protection Forces (IDF) said that “Ali Khamenei was focused in a exact, large-scale operation carried out by the Israeli Air Power, guided by correct IDF intelligence, whereas he was in his central management compound within the coronary heart of Tehran, the place he was along with extra senior officers”. This account of the operation, in addition to different official statements, clearly point out that Khamenei was not killed in some non-public feud unrelated to the battle, however was focused as an integral a part of the armed hostilities with Iran.
“Second shot” idea?
This leaves the second risk. Basic Dan Caine, Chairman of the Joint Chiefs of Workers, described the strike on Khamenei as a “set off occasion”. If the strike on Khamenei was the opening act of the battle, this brings into play the controversy as as to if or not the legislation of armed battle applies to the very first act of violence in an armed battle. There are two competing views on the matter.
The dominant place holds that the legislation of armed battle applies as quickly as one State employs armed power in opposition to one other and that it governs the primary hostile act itself. This place derives help from the legislation itself. Whereas the majority of the legislation of armed battle is engaged solely throughout precise hostilities, sure guidelines are expressly relevant always, together with in instances of peace. The existence of an armed battle is due to this fact not an absolute precondition for legislation of armed battle obligations to be engaged. Those that plan or determine upon assaults have sure precautionary obligations, for instance the responsibility to confirm that the aims to be attacked are neither civilians nor civilian objects and aren’t topic to particular safety, however are army aims. That is an obligation that precedes the precise execution of an assault and thus its results. Put otherwise, targets have to be verified earlier than bombs are dropped on them. There may be nothing within the legislation of armed battle that means that this responsibility is one way or the other inapplicable to the opening act of an armed battle.
The competing view argues that the legislation of armed battle can’t apply to the primary act of violence, since it’s that very act which triggers the applicability of the legislation within the first place. The legislation of armed battle due to this fact can solely apply to the “second shot” fired within the battle. This argument is motivated largely by causes of coverage. If the legislation of armed battle would apply to the primary shot, then a State finishing up a focused killing of a member of one other State’s armed forces would by no means violate the best to life, since below the legislation of armed battle such a focused killing could be permissible and therefore not arbitrary from a human rights legislation perspective. Consequently, States may depend on the legislation of armed battle to assassinate particular person combatants belonging to unfriendly powers. The killing of Qasem Soleimani illustrates the purpose.
Within the current case, the “second shot” view just isn’t compelling. First, it’s a minority place which doesn’t, as famous, replicate the obligations imposed by the legislation of armed battle, specifically the responsibility to take precautions in assault.
Second, the “second shot” argument is supposed to stop States from invoking the legislation of armed battle to justify an remoted focused killing. As Agnès Callamard famous in relation to the Soleimani killing, “one could interrogate whether or not [law of armed conflict] requirements are one of the best ‘match,’ for lack of a greater phrase, to evaluate the act and the scenario” in such remoted incidents. That could be a honest query. Nevertheless, the factual circumstances within the current case are completely completely different. We aren’t confronted with a single focused strike, however with large-scale hostilities of which the killing of Khamenei shaped only one half.
Third, the belief that the legislation of armed battle shouldn’t be triggered too simply as this would possibly overlay or displace the extra protecting regime of human rights legislation doesn’t at all times maintain water. An enchantment to human rights legislation stays largely theoretical if the belligerent States concerned don’t settle for that their human rights obligations are engaged in an extra-territorial setting and if no avenues for efficient treatment exist. Furthermore, whereas the best to life could provide options in relation to the concentrating on of individuals, it isn’t clear what human rights guidelines would govern the destruction of public property, whether or not army or civilian, belonging to a hostile energy.
Fourth, conducting an air marketing campaign in opposition to a succesful adversary in a contested airspace poses apparent operational dangers. It might be relatively shocking to search out that the battle started with the Israeli Air Power casually flying over Tehran to drop a bomb on Khamenei’s compound. Reporting means that this isn’t how the occasions unfolded. Whereas the exact sequence of occasions is troublesome to reconstruct based mostly on data accessible within the public area, it seems that hostilities started with cyber and digital warfare measures designed to disrupt and degrade Iran’s communications and different capabilities, adopted by kinetic strikes by the US and Israel. These strikes included Tomahawk missiles fired by the US in opposition to Iranian command and management services, missile and drone launch websites, air defence capabilities and army airfields. It seems that these missiles had been fired earlier than Israeli plane launched their missiles on Khamenei’s compound and that targets exterior Tehran had been struck earlier than the compound was hit in Tehran.
Even when the “second shot” idea would replicate the legislation and making use of it to the current case could be applicable for coverage causes, neither of which is the case, it might nonetheless be inapplicable based mostly on the info, as it’s virtually sure that different assaults preceded the strike on Khamenei’s compound.
Accordingly, there seems to be no foundation for the assertion that Khamenei was killed “exterior an armed battle”.
