Politics Among Nations: The Struggle for Power and Peace is a political science book by Hans Morgenthau published in 1948. It is considered among the most influential works in international relations on classical realism. [1]
Trained as an international lawyer, the publication of the book culminates a transformation in Morgenthau's intellectual trajectory from focusing on legal theory to focusing on international politics. [2]
The book introduces the concept of political realism, presenting a realist view of power politics. This concept played a major role in the foreign policy of the United States, which made it exercise globe spanning power in the Cold War period. The concept also called for a reconciliation of power politics with the idealistic ethics of earlier American discussions about foreign policy.
John Mearsheimer describes it as among the three most influential realist works of international relations of the 20th century. [3]
It has been criticized for contradictions, ambiguity and vagueness. [1] For example, key concepts "national interest" and "balance of power" are not coherently defined. [1]
Neorealism or structural realism is a theory of international relations that emphasizes the role of power politics in international relations, sees competition and conflict as enduring features and sees limited potential for cooperation. The anarchic state of the international system means that states cannot be certain of other states' intentions and their security, thus prompting them to engage in power politics.
Realpolitik is the approach of conducting diplomatic or political policies based primarily on considerations of given circumstances and factors, rather than strictly following ideological, moral, or ethical premises. In this respect, it shares aspects of its philosophical approach with those of realism and pragmatism.
International relations is an academic discipline. In a broader sense, the study of IR, in addition to multilateral relations, concerns all activities among states—such as war, diplomacy, trade, and foreign policy—as well as relations with and among other international actors, such as intergovernmental organizations (IGOs), international nongovernmental organizations (INGOs), international legal bodies, and multinational corporations (MNCs).
International relations theory is the study of international relations (IR) from a theoretical perspective. It seeks to explain behaviors and outcomes in international politics. The three most prominent schools of thought are realism, liberalism and constructivism. Whereas realism and liberalism make broad and specific predictions about international relations, constructivism and rational choice are methodological approaches that focus on certain types of social explanation for phenomena.
Hans Joachim Morgenthau was a German-American jurist and political scientist who was one of the major 20th-century figures in the study of international relations. Morgenthau was born in Coburg, Germany in 1904. Morgenthau's works belong to the tradition of realism in international relations theory; he is usually considered among the most influential realists of the post-World War II period. Morgenthau made landmark contributions to international relations theory and the study of international law. His Politics Among Nations, first published in 1948, went through five editions during his lifetime and was widely adopted as a textbook in U.S. universities. While Morgenthau emphasized the centrality of power and "the national interest," the subtitle of Politics Among Nations—"the struggle for power and peace"—indicates his concern not only with the struggle for power but also with the ways in which it is limited by ethical and legal norms.
John Joseph Mearsheimer is an American political scientist and international relations scholar. He is the R. Wendell Harrison Distinguished Service Professor at the University of Chicago.
The Twenty Years' Crisis: 1919–1939: An Introduction to the Study of International Relations is a book on international relations written by E. H. Carr. The book was written in the 1930s shortly before the outbreak of World War II in Europe and the first edition was published in September 1939, shortly after the war's outbreak; a second edition was published in 1946. In the revised edition, Carr did not "re-write every passage which had been in someway modified by the subsequent course of events", but rather decided "to modify a few sentences" and undertake other small efforts to improve the clarity of the work.
International security is a term which refers to the measures taken by states and international organizations, such as the United Nations, European Union, and others, to ensure mutual survival and safety. These measures include military action and diplomatic agreements such as treaties and conventions. International and national security are invariably linked. International security is national security or state security in the global arena.
Realism, a school of thought in international relations theory, is a theoretical framework that views world politics as an enduring competition among self-interested states vying for power and positioning within an anarchic global system devoid of a centralized authority. It centers on states as rational primary actors navigating a system shaped by power politics, national interest, and a pursuit of security and self-preservation.
Offensive realism is a structural theory in international relations that belongs to the neorealist school of thought and was put forward by the political scholar John Mearsheimer in response to defensive realism. Offensive realism holds that the anarchic nature of the international system is responsible for the promotion of aggressive state behavior in international politics. The theory fundamentally differs from defensive realism by depicting great powers as power-maximizing revisionists privileging buck-passing and self-promotion over balancing strategies in their consistent aim to dominate the international system. The theory brings important alternative contributions for the study and understanding of international relations but remains the subject of criticism.
Robert Gilpin was an American political scientist. He was Professor of Politics and International Affairs at the Woodrow Wilson School of Public and International Affairs at Princeton University where he held the Eisenhower professorship.
In international relations theory, the concept of anarchy is the idea that the world lacks any supreme authority or sovereignty. In an anarchic state, there is no hierarchically superior, coercive power that can resolve disputes, enforce law, or order the system of international politics. In international relations, anarchy is widely accepted as the starting point for international relations theory.
The balance of power theory in international relations suggests that states may secure their survival by preventing any one state from gaining enough military power to dominate all others. If one state becomes much stronger, the theory predicts it will take advantage of its weaker neighbors, thereby driving them to unite in a defensive coalition. Some realists maintain that a balance-of-power system is more stable than one with a dominant state, as aggression is unprofitable when there is equilibrium of power between rival coalitions.
Kenneth W. Thompson was an American academic and author known for his contributions to normative theory in international relations. In 1978 he became director of the Miller Center of Public Affairs at the University of Virginia. He retired as director in 1998, but continued to head its Forum Program until 2004.
Defensive neorealism is a structural theory in international relations that is derived from the school of neorealism. The theory finds its foundation in the political scientist Kenneth Waltz's Theory of International Politics in which Waltz argues that the anarchical structure of the international system encourages states to maintain moderate and reserved policies to attain national security. In contrast, offensive realism assumes that states seek to maximize their power and influence to achieve security through domination and hegemony. Defensive neorealism asserts that aggressive expansion as promoted by offensive neorealists upsets the tendency of states to conform to the balance of power theory, thereby decreasing the primary objective of the state, which they argue to be the ensuring of its security. Defensive realism denies neither the reality of interstate conflict or that incentives for state expansion exist, but it contends that those incentives are sporadic, rather than endemic. Defensive neorealism points towards "structural modifiers," such as the security dilemma and geography, and elite beliefs and perceptions to explain the outbreak of conflict.
Theory of International Politics is a 1979 book on international relations theory by Kenneth Waltz that creates a structural realist theory, neorealism, to explain international relations. Taking into account the influence of neoclassical economic theory, Waltz argued that the fundamental "ordering principle" (p. 88) of the international political system is anarchy, which is defined by the presence of "functionally undifferentiated" (p. 97) individual state actors lacking "relations of super- and subordination" (p. 88) that are distinguished only by their varying capabilities.
Liberal institutionalism is a theory of international relations that holds that international cooperation between states is feasible and sustainable, and that such cooperation can reduce conflict and competition. Neoliberalism is a revised version of liberalism. Alongside neorealism, liberal institutionalism is one of the two most influential contemporary approaches to international relations.
Classical realism is an international relations theory from the realist school of thought. Realism makes the following assumptions: states are the main actors in the international relations system, there is no supranational international authority, states act in their own self-interest, and states want power for self-preservation. Classical realism differs from other forms of realism in that it places specific emphasis on human nature and domestic politics as the key factor in explaining state behavior and the causes of inter-state conflict. Classical realist theory adopts a pessimistic view of human nature and argues that humans are not inherently benevolent but instead they are self-interested and act out of fear or aggression. Furthermore, it emphasizes that this human nature is reflected by states in international politics due to international anarchy.
Scientific Man versus Power Politics is a 1946 work by realist academic Hans Morgenthau. The book contains Morgenthau's most systematic exposition of a realist philosophy and a critique of a position he terms 'liberal rationalism'. Morgenthau argues that liberalism's belief in human reason had been shown to be deficient because of the rise of Nazi Germany and that emphasis on science and reason as routes to peace meant that states were losing touch with historic traditions of statecraft. The work marked out Morgenthau as the pre-eminent modern exponent of a Hobbesian view of human nature in international relations scholarship. Despite the contemporary association between (neo)realism and positivism Scientific Man has been considered a critique of attempts to place politics on a 'scientific' footing in works such as Charles Merriam's New Aspects of Politics.
The Atlantic Realists: Empire and International Political Thought Between Germany and the United States is a book by American historian, academic, and author Matthew G. Specter. It was published in 2022 by Stanford University Press.
