Qasem Suleimani’s death has been described as probably illegal by the UN special rapporteur on extra-judicial killings, Agnes Callamard, as his killing was based on the immanent threat he posed to the US. The UN has strict guidelines for such acts of preemptive self-defence to be recognised as legal, and so far the US government have not done a good job of justifying their actions. Many commentators have mentioned the lack of congressional support which may raise political problems in the US, but without adequate justification this strike was illegal internationally, and according to US Secretary of State, Mike Pompeo, the US didn't know where or when these ‘imminent attacks’ would occur, which completely undermines any claim to self-defence. Furthermore, the efforts to kill another Iranian operative in Yemen that failed show that Soleimani’s murder was actually part of an chance assassination campaign and not a pre-emptive strike to stop a strike on the US. In this way the death of Qasem Soleimani demonstrates an American assassination campaign and the US government's willingness to lie about it.
