Classical realism and Morgenthau in particular have recently experienced a revived interest in International Relations (IR). The evolving debate has helped to contextualise and reconstruct Morgenthau's thought which until now had been misrepresented in structural realist and early poststructuralist interpretations. However, despite all of its achievements, we have yet to draw more attention to Morgenthau's contribution to contemporary IR theory. To contribute to the closing of this research gap this article considers a set of questions which Morgenthau himself asked at (...) the beginning of his career as its conceptual framework. It is argued that Morgenthau was particularly concerned with the dehumanisation of socio-political life in modern democracies evoked through processes of ideologisation, technologisation, and scientification, which he countered by focusing on a re-introduction of the human factor to politics. This demonstrates that Morgenthau's work is a rich source for IR theory because his intellectual agenda was driven by concerns similar to what we find in poststructuralism. (shrink)

This article investigates the formal purpose of declaring wars for Hugo Grotius. Grotius was adamant that states always use justification in a duplicitous way to conceal their real motivation to go to war. As such, the purpose of declaration is not to assert the just cause of war. Rather, what any public declaration does, is provide recognition that confers legal validation to the disputing parties. The legal rules of war were described by the law of nations and occasionally permitted states (...) to commit certain ‘war crimes’ with impunity. For Grotius, this was not a moral sanctioning of such crimes but rather a means to prevent the occurrence of wars, which such endless repudiations risked causing or exacerbating. Grotius’s concern for the effects of war is conspicuous; and recounting his maxim that war should always be a last resort, this article argues that declaration of war has a distinct moral purpose for Grotius. In fact, public declaration of war is, together with constraints on the conduct of war, a ‘principle of moderation’ Grotius insists should be upheld in times of war. Declaration of war gives the parties avenues to seek peace and reconciliation, and, therefore has a humanitarian purpose for Grotius by ultimately seeking to prevent the disparaging effects of war. Even in wars that do not demand a public declaration, such as those regulated by natural law such as punitive wars or defensive wars, Grotius cautions that declarations of war are advisable. The remaining lingering issue is how to engage with unlawful enemy combatants, such as pirates - a distinct problem that the international community still faces with increasing regularity. Grotius was certainly aware of the legal consequences of recognising belligerency we cannot possible hope to build moral relations with, and, this article claims, ‘unlawful’ enemies ultimately demarcates the boundary of international society.

World War I was an epochal event that permanently redefined international politics. Yet, there is no consensus about what kind of international system it erected. This article argues that since 191...

Modern jurisprudence has typically been presented as a debate between legal positivism and natural law. Though the demise of legal positivism has been touted despite its pre-eminence in past decades, it is clear that there remains a vigorous debate surrounding this theory. It is noteworthy that Hans J. Morgenthau’s legal thought and critique of legal positivism have remained unexplored in the context of this debate. Largely forgotten, his legal thought answers questions that lie at the heart of the natural law (...) and legal positivist debate. It showcases his deeply nuanced understanding of legal and political theory and contains a powerful and insightful commentary on the fundamental problems faced by international law. Building on existing literature, this paper unearths Morgenthau’s critique of legal positivism. It does this by re-examining his works, which address the question of whether moral considerations are relevant to determining the content of the law in force. It brings his legal thought to light, which highlights the artificiality of the division between law and morality and offers a nuanced analysis of problems inherent in international law. Ultimately, the paper challenges the claim that the law can be determined without resorting to moral judgement and shows how Morgenthau’s insights remain relevant to legal positivism and natural law debates today.
