Ever since the Nuremberg trials, however\u2014and despite the 1946 UN General Assembly affirmation of the principles of Nuremberg, which, it has authoritatively been argued, conferred upon these principles the status of customary law<a href=\"#_ftn2\" name=\"_ftnref2\">[1]<\/a>\u2014the articulation of the prohibition against the use of force was abandoned in the international criminal sphere and left to the United Nations system of enforcement and maintenance of international peace and security. The relatively recent history of the normative development of the prohibition itself and the controversies surrounding the justiciability of breaches of this prohibition as crimes under international law are but two indicators of the chronic unpopularity that has accompanied efforts to outlaw and sanction armed conflict throughout modern history. After years of lengthy negotiations, in 2017 the international legal community will have the opportunity to reconsider its commitment to the precedent it established in Nuremberg. This might, in fact, be the year that the law on the use of force and international criminal law converge again after seventy years of separation and idiosyncrasy.<a href=\"#_ftn3\" name=\"_ftnref3\">[2]<\/a> With accountability for violations of the prohibition against the use of force at a crossroads, this contribution is dedicated to its normative history, and to the possibility of a normative convergence in the near future.<\/p>\n<p style=\"text-align: center\">***<\/p>\n<p style=\"text-align: justify\"><em>A brief period of overlap.<\/em> The prohibition against the use of force has been recognized as the bedrock of public international law since the end of World War II. Although some have disagreed with this notion,<a href=\"#_ftn4\" name=\"_ftnref4\">[3]<\/a> the prohibition against the use of force is widely recognized a <em>jus cogens<\/em> norm of peremptory character, whose scope has been defined in multiple international legal instruments, including the founding document of the United Nations (UN), and in the jurisprudence of international tribunals.<a href=\"#_ftn5\" name=\"_ftnref5\">[4]<\/a> In 1945, article 2(4) of the United Nations Charter imposed an absolute prohibition against the use of force, requiring that all Member States \u201crefrain in their international relations from the threat or use of force against the territorial integrity or political independence of any State, or in any other manner inconsistent with the Purposes of the United Nations.\u201d The sole exceptions to this rule were made for instances of the use of force in individual or collective self-defense and for the use of force to combat threats to international peace and security under the executive power of the newly established UN Security Council.<a href=\"#_ftn6\" name=\"_ftnref6\">[5]<\/a> Rising from the ashes of the most devastating conflict in history, states had finally outlawed war as a legitimate means of conducting themselves in the international arena.<a href=\"#_ftn7\" name=\"_ftnref7\">[6]<\/a> That principle underpinned the new system of international law and relations that still governs us today.<\/p>\n<p style=\"text-align: justify\">After the end of World War II and amidst much controversy,<a href=\"#_ftn8\" name=\"_ftnref8\">[7]<\/a> violations of the prohibition against the use of force were also recognized as crimes under international law warranting the adjudication of individual criminal responsibility as \u201ccrimes against peace.\u201d Under the law of the International Military Tribunals at Tokyo and Nuremberg, the \u201cplanning, preparation, initiation or waging of\u00a0wars of aggression, or a war in violation of international treaties, agreements or assurances, or participation in a common plan or conspiracy for the accomplishment of any of the foregoing\u201d was recognized as the \u201csupreme international crime\u201d that differed from other international crimes only in that \u201cit contains within itself the accumulated evil of the whole.\u201d<a href=\"#_ftn9\" name=\"_ftnref9\">[8]<\/a> The criminalization of the illegal use of force was hailed as a step forward for accountability and as a \u201csafeguard [of] the future\u00a0peace and security\u00a0of this war-stricken world.\u201d<a href=\"#_ftn10\" name=\"_ftnref10\">[9]<\/a> Nuremberg itself and the subsequent trials<a href=\"#_ftn11\" name=\"_ftnref11\">[10]<\/a> have been defined as the most successful \u201cplea of humanity to law\u201d<a href=\"#_ftn12\" name=\"_ftnref12\">[11]<\/a> and \u201cone of the most significant tributes that Power has ever paid to Reason.\u201d<a href=\"#_ftn13\" name=\"_ftnref13\">[12]<\/a><\/p>\n<p style=\"text-align: center\">***<\/p>\n<p style=\"text-align: justify\"><em>Between idiosyncrasy and symbiosis: from Nuremberg to Kampala<\/em>. Despite the enthusiasm at the time, and notwithstanding the consistent best efforts of a committed group of individuals, including the indefatigable Benjamin Ferencz, criminal liability for violations of the prohibition against the use of force was relegated to the status of a memory from the recent past for the next seventy years.<a href=\"#_ftn14\" name=\"_ftnref14\">[13]<\/a> In the 1950s, at the request of the General Assembly, the\u00a0International Law Commission\u00a0(ILC) drafted two statutes for a permanent international court that would have received jurisdiction over breaches of the prohibition against the use of force, or \u201caggression,\u201d as it had come to be known, but these were shelved during the\u00a0Cold War, which made the establishment of such court politically unrealistic.<a href=\"#_ftn15\" name=\"_ftnref15\">[14]<\/a> In 1974, the UN General Assembly adopted by consensus a resolution defining the \u201ccrime of aggression,\u201d as \u201cthe use of armed force by a State against the sovereignty, territorial integrity or political independence of another State, or in any other manner inconsistent with the Charter of the United Nations, as set out in this Definition.\u201d Article 5(2) of the resolution clearly stated that \u201ca war of aggression is a crime against international peace,\u201d and that \u201caggression gives rise to international responsibility.\u201d<a href=\"#_ftn16\" name=\"_ftnref16\">[15]<\/a><\/p>\n<p style=\"text-align: justify\">The definition built both on the Nuremberg and Tokyo Charters and on the language and scope of article 2(4) of the UN Charter. Interestingly, however, and contrary to the International Military Tribunal statutes, it avoided specifying whether the responsibility for this \u201ccrime\u201d ought to lay with the individual; moreover, unlike the UN Charter, it did not recognize the \u201cthreat\u201d of the use of force as aggression pursuant to its own definition. The resolution went into some detail, however, by fleshing out which breaches of the prohibition against the use of force did constitute \u201cacts\u201d of aggression (invasion, including occupation and annexation, bombardment, blockade, violation of status of forces agreements, the \u201csending\u201d of armed groups, or any other form of armed attack by sea, air, or land, including the use of one\u2019s territory to launch it),<a href=\"#_ftn17\" name=\"_ftnref17\">[16]<\/a> and by recognizing that \u201caggression is the most serious and dangerous form of the illegal use of force.\u201d<a href=\"#_ftn18\" name=\"_ftnref18\">[17]<\/a><\/p>\n<p style=\"text-align: justify\">These notions were, of course, picked up by the International Court of Justice (ICJ) in much of its reasoning and jurisprudence on the subject of the legality of the use (or threat of the use) of force,<a href=\"#_ftn19\" name=\"_ftnref19\">[18]<\/a> even though only a handful of cases have come before the ICJ on this issue throughout the years.<a href=\"#_ftn20\" name=\"_ftnref20\">[19]<\/a> Although the Court has \u201cnever found that a state has committed aggression,\u201d nor has it \u201cset out a definition of the concept of aggression\u201d or \u201canalyzed the concept in any detail,\u201d nevertheless, \u201callegations of aggression have occasionally found their way before the ICJ.\u201d<a href=\"#_ftn21\" name=\"_ftnref21\">[20]<\/a> Even in cases in which aggression was not alleged <em>as such<\/em>, the Court\u2019s analysis of the legality of the use of force has helped \u201cdevelop[] the law both in relation to the prohibition of the use of force, and in relation to the exceptions to that prohibition.\u201d<a href=\"#_ftn22\" name=\"_ftnref22\">[21]<\/a><\/p>\n<p style=\"text-align: center\">***<\/p>\n<p style=\"text-align: justify\"><em>Towards normative convergence in Kampala. <\/em>The ICJ reasoning on what constitutes and does not constitute an act of aggression was duly taken into consideration during the Kampala negotiations and in the lead up to the negotiations during the <em>travaux pr\u00e9paratoires<\/em> of the Working Group on Aggression.<a href=\"#_ftn23\" name=\"_ftnref23\">[22]<\/a> The drafters were sensitive to the debate surrounding the level of overlap between the substantive and constituent elements of the notion of the illegal use of force as it had developed with respect to state responsibility, as well as to the constituent elements of the penal offense as it was recognized in and subsequent to Nuremberg (including the 1974 definition of aggression). Because of the lack of systematic treatment of the concept of \u201caggression\u201d by the ICJ, however, several positions existed in Kampala as to what should or should not be included in the definition. Article 8 <em>bis<\/em> of the Rome Statute eventually came to distinguish between an<em> act<\/em> of aggression and a <em>crime<\/em> of aggression. For the purpose of the Rome Statute, a crime of aggression was defined as an \u201cact of aggression, which by its <em>character, gravity and scale<\/em>, constitutes a <em>manifest<\/em> violation of the Charter of the United Nations.\u201d<a href=\"#_ftn24\" name=\"_ftnref24\">[23]<\/a> An act of aggression, for the purposes of the Statute, is thus a constituent element of a crime of aggression and, coherently with the 1974 definition of aggression, is any of the following acts: invasion (including occupation and annexation), bombardment, blockade, violation of Status of Forces agreements, the \u201csending\u201d of armed groups, or any other form of \u201carmed attack\u201d by sea, by air, or by land, including the use of one\u2019s territory to launch it. <a href=\"#_ftn25\" name=\"_ftnref25\"><sup>[24]<\/sup><\/a><\/p>\n<p style=\"text-align: justify\">The \u201cmanifest\u201d threshold for the criminal offense concerning the gravity, scale, and character of the violations (as cumulative elements) was intended to exclude \u201cborderline cases\u201d (as it would be the case, for example, with border skirmishes). It was also intended to exclude cases falling within a gray area both factually (when the act of state does not meet the required \u201cgravity\u201d or \u201cscale,\u201d such as in minimal boarder incursions), as well as legally (that is, debatable cases, where the act of state does not constitute a manifest violation of the Charter due to its \u201ccharacter\u201d). This language is, of course, fruit of diplomatic compromise and has been harshly criticized,<a href=\"#_ftn26\" name=\"_ftnref26\">[25]<\/a> but it ought to be understood in light of the \u201cdifferent speeds\u201d at which states mature and develop their own understanding of what the prohibition against the use of force in international law prescribes or proscribes, particularly with respect to exceptions to the prohibition. The controversy in Kampala over so-called \u201cunilateral humanitarian interventions\u201d is an emblematic example of this.<\/p>\n<p style=\"text-align: justify\">Humanitarian interventions (that is, non-UNSC sanctioned use of military force in the territory of a non-consenting state to halt or prevent war crimes, crimes against humanity, genocide, and ethnic cleansing) were discussed as possible exceptions falling under the latter category of non-manifest violations, and a memorandum of understanding to this extent was proposed by the United States to the Assembly in Kampala. Ultimately, however, the memorandum of understanding was not adopted because unilateral humanitarian interventions have not crystallized as exceptions to the prohibition against the use of force under international law.<a href=\"#_ftn27\" name=\"_ftnref27\"><sup>[26]<\/sup><\/a> To the contrary, although the 2001\u00a0International Commission on Intervention and\u00a0State\u00a0Sovereignty\u2019s Final Report theorized that a \u201cresponsibility to protect\u201d civilians from atrocity crimes exists, both the\u00a02004 High-Level Panel on Threats, Challenges and Change, and the Secretary-General\u2019s own 2005 Report in Larger Freedoms concluded that under existing law, such responsibility can be exercised <em>only<\/em> under the authority of the Security Council.<a href=\"#_ftn28\" name=\"_ftnref28\">[27]<\/a><\/p>\n<p style=\"text-align: justify\">Of course, academic, policy, and ethical disagreement over humanitarian interventions continue to date.<a href=\"#_ftn29\" name=\"_ftnref29\">[28]<\/a> Other international law \u201cdoctrines\u201d might be equally invoked in future debates over \u201cgray areas\u201d in the definition of <em>acts<\/em> of aggression concerning, for example, the \u201cprotection of nationals abroad\u201d (most often taking shape in the form of \u201cnon-combatant evacuation operations,\u201d or NEOs) and self-defense against non-state armed groups. Insofar as the <em>crime<\/em> of aggression is concerned, however, the manifest threshold introduced in the definition intentionally excludes all such instances of the use of force. It is exactly for this reason that those with a restrictive view on the law on the use of force\u2014including, notably Benjamin Ferencz\u2014have argued that the definition agreed upon in Kampala did not go far enough if we consider deterrence from the illegal use of force the ultimate goal of the criminalizing aggression in the first place. Alternative theories have been advanced, arguing that the illegal use of force may be prosecuted as a war crime in some circumstances (of disproportionate attack, for example)<a href=\"#_ftn30\" name=\"_ftnref30\">[29]<\/a> or as a crime against humanity in and of itself.<a href=\"#_ftn31\" name=\"_ftnref31\">[30]<\/a> Whether these theories will gain support among scholars and experts is yet to be seen. Early reactions to these ideas, however, do not seem to preclude the coexistence of such theories and the framework agreed upon at Kampala. The specific arguments, moreover, cannot be discounted as being without merit.<\/p>\n<p style=\"text-align: center\">***<\/p>\n<p style=\"text-align: justify\">In conclusion, the substantive aspects of the debate surrounding criminal accountability for the illegal use of force are not marginal. The legislative history of aggression from Nuremberg to the Kampala negotiations is illustrative of the symbiotic but idiosyncratic relationship that has characterized the various strands of public international law that deal with questions concerning the legitimacy and lawfulness of the use of force. From a normative perspective, the observance of how developments in the law on the use of force have influenced and may or may not influence again the definition of the <em>crime<\/em> of aggression, or may be conducive to an expansive interpretation of other judiciable offenses, is fascinating. And if normative developments demand that standing definitions of crimes or interpretations of these definitions be changed, surely the international community will have future opportunities to revisit the issue. Indeed, perhaps the international community will revisit the most appropriate penal characterization for the illegality of the use of force that results in the death of score of innocent civilians.<a href=\"#_ftn32\" name=\"_ftnref32\">[31]<\/a> At the current stage, however, the question is whether or not the international community will honor its original commitment to make the \u201csupreme international crime\u201d again a judiciable offense\u2014or, as this essay ponders, whether 2017 will be the year that the law on the use of force and international criminal law converge again after seventy years of separation. Even if no convictions are obtained under the current definition of the crime of aggression, the symbolic power of completing the Nuremberg legacy\u2014and the prospect of adding a further tool for deterring military adventurism, contributing to the maintenance of international peace and security in a manner compatible with the requirements of the UN Charter\u2014seems a worthwhile endeavor, especially in a nuclear age.<\/p>\n<hr \/>\n<p style=\"text-align: justify\"><a href=\"#_ftnref1\" name=\"_ftn1\">* Federica D\u2019Alessandra<\/a> is a Visiting Researcher in residence at the Harvard Law School Graduate Program, where she is conducting research on the interaction between the law on the use of force, international criminal law, and international human rights law.
