This chapter examines the use of remotely piloted and other robotics during war and outside the context of war during permissible measures of self-defence and their implications for the jus ad bellum, interpretation of Articles 2(4) and 51 of the UN Charter, and applications of underlying general principles. It discusses the phenomenon of ‘remotely piloted warfare’ as it applies to the use of force by state and non-state actors with respect to self-defence, collective self-defence, self-determination assistance, regional action, and enforcement action authorized by the Security Council. It then considers the use of remotely piloted attacks, self-defence, and warfare in relation to compliance with the principles of reasonable necessity, distinction in targeting, and proportionality. In particular, the chapter looks at the use of weaponized drones and the possible challenges they present to compliance with basic legal principles that limit violence, and some current applications and issues regarding compliance.

This chapter explores the justness, legitimacy, and legality of war. While 1945 was a key turning point in the codification of jus ad bellum (i.e. international law on the use of force), that framework did not emerge in a vacuum. Rather, it was the product of historical political contingencies that meant that codification of the laws of war was contemporaneous, both geographically and temporally, with the solidification of the norms of sovereign nation-statehood and territorial integrity. The chapter focuses on the UN Charter regime and how it has shaped the politics of war since 1945. Importantly, the Charter establishes a general prohibition on the use of force in international relations. It also grants two exceptions to the prohibition: actions undertaken with Security Council authorization and actions taken in self-defence. Today, many of the most serious challenges to the Charter regime concern the definition and outer limits of the concept of self-defence. Another set of challenges to the Charter regime concerns the contested concept of ‘humanitarian intervention’. The chapter then looks at the development of the ‘Responsibility to Protect’ doctrine.

This chapter discusses international law governing the use or threat of force by states. The UN Security Council has primary responsibility for enforcement action to deal with breaches of the peace, threats to the peace, or acts of aggression. Individual member states have the right of individual or collective self-defence, but only ‘until the Security Council has taken measures necessary to maintain international peace and security’. However, the practice has evolved of authorizing peacekeeping operations that are contingent upon the consent of the state whose territory is the site of the operations.

This chapter discusses the regulation of when and for what purpose a state may use force against another state jus ad bellum. It provides an overview of the legal framework in the 1945 UN Charter. It analyses the content of the prohibition on the use of force in article 2(4) of the Charter; discusses the competences of the UN Security Council; and examines the right to self-defence. The Security Council is entrusted with primary responsibility for the maintenance of international peace and security and, under Chapter VII of the Charter, the Council may authorize the use of force if required to maintain and/or restore the peace. Article 51 of the Charter allows a state to defend itself in the case of armed attack.

This chapter examines under what circumstances States may use armed force under customary international law and Arts 2(4) and 51 UN Charter. After noting that the use of armed force is generally prohibited and only limited to self-defence, and then only if the target State is under an armed attack, we show that several States have expanded the notion of armed attack. Besides self-defence, the United Nations Security Council may authorize the use of armed force through a process of collective security. Several examples of collective security are offered, as well as the ICJ’s position on what constitutes an armed attack. In recent years, the range of actors capable of undertaking an armed attack has included terrorists. Moreover, the development of the doctrine of the responsibility to protect is a significant achievement.

This chapter looks at the use of force and collective security. Today, the United Nations Charter embodies the indispensable principles of international law on the use of force. These include the prohibition on the unilateral use of force found in Article 2(4), and the recognition of the inherent right of all States to use force in self-defence found in Article 51. Finally, under Chapter VII, a collective security system centred upon the Security Council was established for the maintenance of international peace and security. A key debate over the scope of Article 2(4) is whether a new exception has been recognized which would allow the use of force motivated by humanitarian considerations. It is argued that these ‘humanitarian interventions’ would allow a State to use force to protect people in another State from gross and systematic human rights violations when the target State is unwilling or unable to act.

This chapter addresses the US and NATO-led intervention in Afghanistan from 2001 to the present day. It examines the different legal justifications advanced or available for the intervention, namely self-defence, UN Security Council authorization, and intervention by invitation. It explores the complex relationships between these justifications and, particularly, the strategies adopted by states in choosing between them. The chapter concludes by considering the effects of the intervention on the customary international law of self-defence as it concerns non-state actors located in “unaware or unable” states, and anticipatory or pre-emptive responses.
