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 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.

In July 2021, the author presented a Special Course for the Hague Academy of International Law Summer Courses on the Extraterritorial Use of Force against Non-State Actors. The course focused on two bases for the extraterritorial use of force against non-state actors, namely self-defence and intervention by invitation. The lectures came to a conclusion that may, at first glance, appear contradictory. With respect to the use of force in self-defence, the lectures adopted a restrictive (non-permissive) approach in which the use of force is not permitted save in narrowly construed exceptions. With respect to intervention by invitation, the lectures adopted a more permissive approach in which the use of force is generally permitted and prohibited only in narrowly construed exceptions. This article serves as post-script (PS), to explain the apparent contradiction. It concludes that the main reason for this apparent contradiction is the application of the fundamental principles of international law—sovereignty, territorial integrity and independence—which are consistent with intervention by invitation but are undermined by self-defence against non-state actors.

This chapter examines the proliferation of weapons of mass destruction (WMD) between states and non-state actors and its implications for international law governing the use of force. It considers whether WMD proliferation and changes in security realities have brought a crisis in international law on the use of force and discusses the use of pre-emptive force for preventing states and non-state actors ‘of concern’ from developing and using WMD. It analyses the shift in the policy positions of the US and other relatively powerful states, from more multilateral and diplomacy-based ‘non-proliferation’ to increased emphasis on proactive and often unilateral or small-coalition-based ‘counterproliferation’. It looks at concerns that several states will be emboldened to apply the doctrine of counterproliferation-oriented pre-emption to their regional conflicts. Finally, it evaluates proposals to reform the provisions and procedures of the UN Charter system for regulating the use of force, including the law on self-defence.

This chapter examines the distinction between self-defence and collective security, the two principal exceptions to the prohibition of the use of force in international law. The exercise of the right of self-defence, which includes collective self-defence, is recognized by Article 51 of the UN Charter, while collective security measures are authorized by the UN Security Council under Chapter VII of the Charter. Drawing on an article by Derek Bowett published in 1994, the chapter considers the academic debate and confusion in 1990–1 concerning the distinction between self-defence and collective security. In particular, it looks at the controversy regarding the legal basis of the use of force over Korea in 1950. It also outlines six differences identified by Bowett with regard to collective self-defence and collective measures under Chapter VII.

O TERRORISMO E O USO DA FORÇA NO DIREITO INTERNACIONAL  TERRORISM AND USE OF FORCE IN INTERNATIONAL LAW   Chiara Antonia Sofia Mafrica Biazi*David Fernando Santiago Villena del Carpio**  RESUMO: O presente artigo aborda a questão do terrorismo sob a perspectiva do direito internacional. Traça um histórico do fenômeno do terrorismo, apontando suas raízes bastante antigas, e se debruça sobre as políticas dos Estados voltadas à segurança após 11/9. Considerado um marco tanto na política quanto no direito internacional, o fenômeno do terrorismo traz à tona diversas discussões, como as que dizem respeito à legalidade do uso da força para combatê-lo. Após analisar as exceções previstas no direito internacional à proibição do uso da força, o artigo aborda a possibilidade de se usar a força em legítima defesa contra entidades não estatais, nomeadamente grupos terroristas, trazendo os debates pertinentes da doutrina. PALAVRAS-CHAVE: Terrorismo. Direito Internacional. 11/9. Uso da Força. ABSTRACT: This article tackles the issue of terrorism from the perspective of International law. It sets forth a brief history of the phenomenon of terrorism, by pointing out its ancient roots, and dwells on the security-oriented States´ policies after 9/11. Regarded as a milestone both in politics and International law, the phenomenon of terrorism brings up various debates, such as those relating to the legality of the use of force in order to fight against it. After assessing the exceptions to the prohibition of the use of force which international law foresees, the article tackles the possibility of using force in self-defence against non-state actors, namely terrorist groups, putting forward the relevant theoretical discussions on the subject. KEYWORDS: Terrorism.

The article investigates how the so-called perpetual peace projects contributed to the scholarly thought of international law. Such projects have been proposed for centuries and came to constitute a rather remarkable trend in human thought, many of them being created by people, prominent of history and representing various fields of activity. Although such projects may be considered an interdisciplinary invention, their contribution to the development of the concepts and ideas of international law can be esteemed as especially significant. The meaning of some famous examples of such projects is summarized. The conclusion is made that among the traces of the influence that the perpetual peace projects had upon the scholarly thought of international law are the preservation and propaganda of the idea of peace, the acknowledgment of law and its means as a valuable component of peace achievement, the investigation of the causes of peace-breaking and combating them, the formation of the principles of peaceful settlement of international disputes and of non-use of force or threat of force, the establishing of theoretical grounds for creating international organizations and elaborating the concept of collective security.

Abstract Sweden’s territorial sea and internal waters have experienced regular intrusions by submerged foreign submarines since the early 1950s. The response of the country to such intrusions is generally well-documented and mainly public. The present article offers an overview of the development of the relevant national legislation, the actual response of the naval forces, and the legal arguments invoked at national level to justify or dismiss use of force in self-defence or under another title. The article discusses the relevance of the immunity that submarines normally enjoy under international law and Sweden’s human-rights obligations, two issues that have been at the centre of the legal discourse. Particular attention is paid to developments since 2014 when a new round of “submarine hunts” started and led to the adoption of new measures both revising the existing laws and strengthening the defence forces.
