1 The Leuven Manual, and this book review, refer to “peace operations” as including both peacekeeping missions and peacebuilding and conflict resolution operations. This choice reflects current United Nations (UN) terminology. On 1 January 2019, the UN Department of Peace Operations (DPO) replaced the Department of Peacekeeping Operations (DPKO). The new DPO combines the functions of the former DPKO with responsibility over field-based political missions previously under the purview of the Department of Political Affairs. See Restructuring of the United Nations Peace and Security Pillar : Report of the Secretary-General, UN Doc. A/72/525, 13 October 2017, para. 20 (approved by UNGA Res. 72/262 C, 5 July 2018), available at: www.un.org/en/ga/search/view_doc.asp?symbol=A/72/525 (all internet references were accessed in March 2019).

5 The distinction between “peace operations”, “enforcement operations” and “peace enforcement operations” is today a conventional one. See Gill, Terry D., Fleck, Dieter, Cammaert, Patrick C. and Klappe, Ben F., “Peace Operations”, in Gill, Terry D. and Fleck, Dieter (eds), The Handbook of the International Law of Military Operations, 2nd ed., Oxford University Press, Oxford, 2015, p. 153Google Scholar; Findlay, Trevor, The Use of Force in UN Peace Operations, Oxford University Press, Oxford, 2002, pp. 3–7Google Scholar.
6 There have been only two uncontroversial examples of enforcement operations (in Korea from 1950 to 1953 and Operation Desert Storm against the Iraqi invasion of Kuwait in 1991) and a few more cases of peace enforcement operations. The latter include the mandate of the UN Operation in the Congo between 1961 and 1963, and, more recently, the Force Intervention Brigade of the UN Stabilization Mission in the Democratic Republic of the Congo since 2013. It is still disputed whether the robust mandate attributed to the UN Multidimensional Integrated Stabilization Mission in Mali qualifies as peace enforcement. Examples of non-UN peace enforcement operations are the International Security Assistance Force in Afghanistan and the Kosovo Force, both led by NATO. See T. Findlay, above note 5, pp. 374–381; T. D. Gill et al., above note 5, pp. 96–97.

25 Provided that notably the requirement of belligerent nexus is fulfilled.
26 In order to determine whether an attack is unlawful for the purposes of direct participation in hostilities, what must be taken into consideration is the nature of the target, not the nature of the attacker or the means used.
