GENERAL INTRODUCTION The book you are holding is intended as a tool not only for law students who must pass this subject as part of their curriculum, but also for any professional seeking to pursue a career in the international arena, whether as a lawyer, an international official, a diplomat, in short, in any field having to do with the foreign policy of States. Indeed, these dualities —academics and professional activity, law and diplomacy— provide the foundation for the lessons in this book, which are presented as overviews. The volume does not aim to be a treatise, thoroughly systematizing all knowledge on the subject. Nevertheless, precisely to be useful to these professionals, these overviews are also duly contextualized. Each sector governed by international law is placed in context, its problems and conditioning factors are discussed, and the explanation is enriched with an analysis of the relevant State practice in each case. Diplomacy and international law necessarily go hand in hand. One could even argue that, historically, international law would not have come into existence had it not been preceded by a certain minimum development of diplomacy. Likewise, diplomacy would be inconceivable today without the prior legal framework provided by international law and the limits it imposes. In this regard, the prevalence of one or the other has long been a matter of debate. At the time of publication of this manual, we are witnessing an unprecedented aggression on European soil. The Russian Federation has invaded Ukraine, under the pretext of ‘de-Nazifying’ the government freely elected by the Ukrainian people and protecting certain pro-Russian minorities from an alleged genocide being conducted by that government. Neither international law nor diplomacy have proved particularly successful in preventing or stopping this aggression, casting doubt on the long-standing claim of the prevalence of politics (in the form of diplomacy) over legality and vice versa. The nuance may lie not in the conflict itself, but in the responses to this illegitimate and illegal aggression. For, so far, the responses to this action —which is contrary to all diplomacy and law— have exquisitely adhered to the limits established by international law, both at the political level —with mass statements against Russia’s actions (United Nations General Assembly Resolution A/ EN-11/L.1; Council of Europe CM/Del/Dec8(2022)1426ter/2.3)— and in terms of those responses strictly rooted in the legal terrain, with a regime of targeted economic sanctions agreed in multilateral fora. Despite Russia’s provocations, any recourse to armed force by third States not involved in the conflict has thus been avoided. At the same time, the possibility of lodging claims with the compe-
18
Ana María Salinas de Frías
tent international judicial bodies against the internationally wrongful acts arising from Russia’s unilateral action and seeking the criminal responsibility of their perpetrators is being studied. Today’s international society is globalized, lacking an external space to which to export conflicts between its members (MERLE); contradictory, insofar as this so-called globalization has been pursued only at the economic level (REMIRO), even as barriers have been erected to prevent the free movement of people, including even their ability to flee from the most horrifying conflicts; diverse and heterogeneous in every facet, a society in which Euro-centrism and Christian thought are no longer predominant (CASADO RAIGÓN), but in which there is likewise no room for any other form of groupthink, regardless of the culture and/or religion it might come from; multipolar, with groups of States led by regional powers and a great global power that only acts in certain circumstances and in relation to issues of strict national interest (RODRÍGUEZ CARRIÓN); and subject to continuous stress tests, given the immediacy of information and the unprecedented importance of the use of new technologies able to influence the political evolution of States and their populations in the most unexpected ways. In such a society, diplomacy and law are more necessary than ever. Today’s international law thus cannot be understood without a minimum understanding of the international society on which it is based. In this regard, we are dealing with a society in which States remain the main subject of the international order, but are no longer the only one. This is because relations in the context of this social group are no longer relations of mere co-existence, but also cooperation, favoured by the emergence of international organizations as major players in current international society and the development of a very significant parliamentary diplomacy. Today, the State is sometimes too small to deal with certain challenges (SUR), especially cross-border phenomena, such as security, nowadays under threat not only from a globalized terrorism, but also the environmental problems afflicting the planet. At the same time, the State may be too big to solve certain other problems that are ultimately better dealt with by other types of organizations, such as NGOs, even if they have not yet, as a result, acquired international subjectivity themselves. Other elements present in these relations, such as transnational corporations, the various ‘G-groups’, certain atypical subjects of international law, peoples (with increasing importance), individual persons, or major economic lobbies, play an ever more decisive role within this social group that international law seeks to regulate. All of this has resulted in a limitation and relativization of the sacrosanct concept of State sovereignty in favour of, amongst other things, a more prominent role for the individual person, a phenomenon that has been referred to as the ‘humanization of international law’, as well as a progressive institutionalization of international life through the creation and action of inter-

19
national organizations. Nevertheless, the State remains the core element around which international law is created and applied today. International law cannot be compared to State legal systems, given the lack of a legislative body with the power to make international laws —which, in any case, stem from the will of the State and must be consented to thereby in one way or another to become enforceable— Nor is there a centralized power superior to the States, able to impose respect for the international laws in force on them. It could be argued that this is the key distinctive feature that sets international law apart, the source of both its greatness and its misery (RODRÍGUEZ CARRIÓN), although it has not especially resulted in the mass breach of international norms, as is often claimed. Indeed, whilst claims of a lack of compliance with international law and its uselessness are commonplace, they fail to acknowledge that, precisely because of its consensual nature, international law is characterized by its peaceful and regular implementation in the everyday affairs of States. Certainly, the specific breaches of it are especially serious and regularly make the front pages of the news, but the rate of violations worldwide is no higher than, for example, that of the crimes registered in the world’s different States entailing the repeated breach of domestic criminal laws (REMIRO). In any case, in the face of what might seem to be a naive defence of international law given the evolution of contemporary international society, and keenly aware of its acceptance of an unequal distribution of political power amongst States that places a minority of them in a position of absolute privilege, we will not yield to the temptation —so common in the media and so often put to interested political use— of defending the material existence, today, of an international community, which would entail the real existence of a communion of values amongst the members of the current international society and which has sometimes been conflated with the United Nations and, in particular, its Security Council, resulting in a not insignificant number of misunderstandings (ABI-SAAB). At most, current international society combines relations of mere co-existence with relations of cooperation (FRIEDMANN), such that the law governing them is, at once, a legal system regulating the peaceful co-existence of sovereign and independent entities and the necessary cooperation between them, insofar as they are affected by a growing interdependence. All law arises from a primordial social fact: societal life and the conflict of interests amongst its members. All legal rules can trace their origin to a practical motive, namely, the need to provide a solution to a conflict of interests (CASANOVAS). However, the fact that they are a solution to a conflict does not negate their legal nature, nor make them any less binding, as evidenced by the eagerness of the States involved to justify conducts that ‘deviate’ from the norm

or the existence of an exceptional situation that led to the breach of international obligations in force, such as the 2003 invasion of Iraq, NATO’s controversial intervention in Kosovo, or, today, the reasons put forward by the Russian Federation for its aggression against Ukraine. The foundation and raison d’être of the binding nature of international norms today cannot be sought solely and exclusively in the will of sovereign States, but must also, and simultaneously, be sought in a legal reality that compels States regardless of their sovereign will, insofar as contemporary international law has gone beyond that mere conception of an aseptic compendium of State wills to embrace and protect essential values of contemporary international society (REISSMAN). As has been stated elsewhere, if international law were merely a product of will, it could not be binding on States, and if it really is binding on States, it cannot be merely the product of their will (CARRILLO SALCEDO). A purely objectivist view of international law would be a dangerous illusion; a purely voluntarist view would lead to self-destruction (WEIL). In light of these considerations, the following pages will examine the subjects and sources of contemporary international law, the ways in which it is applied, and how the international legal order responds to the breach of those norms. They will also look at the main material areas governed by this branch of law, placing special emphasis on the role of diplomacy in each case. Málaga, 19 February 2022
