Which of the following thinkers made this statement - "Thus it is not detente that makes for the peace, but it is the nuclear balance that makes both for detente and peace"?

Question

Accepted Answer

The correct option is 1:

The correct option is 1: **Hans J. Morgenthau**. This statement perfectly encapsulates the core tenets of Classical Realism, the school of thought which Hans Morgenthau championed in his seminal work, *Politics Among Nations*. The quote argues that the stability, or "peace," achieved during periods of détente—a relaxation of strained relations, particularly between the US and the USSR during the Cold War—was not a result of goodwill, mutual understanding, or diplomatic efforts alone. Instead, Morgenthau asserts that the peace was fundamentally sustained by the underlying **nuclear balance**, specifically the concept of Mutually Assured Destruction (MAD). In the Realist perspective, power, not cooperation, is the ultimate determinant of international politics. Morgenthau believed that the terrifying equilibrium of nuclear arsenals prevented both superpowers from escalating conflicts, thereby creating a necessary foundation for détente and maintaining a fragile peace. The presence of overwhelming, mutually destructive capability forced prudence upon rational actors, making nuclear balance the true source of stability, a view highly consistent with Morgenthau's emphasis on the primacy of power and security in the international system.

The incorrect option is 2:

C. D. Blacker is primarily known for his detailed research and writings on nuclear strategy, arms control, and Soviet foreign policy, particularly concerning deterrence and the early stages of the post-Cold War era. While Blacker’s work deeply engaged with the themes of nuclear stability and superpower relations, he is not the recognized originator of this specific, highly cited realist critique linking nuclear balance directly to the structural conditions necessary for détente. His focus tends to be more policy-oriented and descriptive regarding Soviet military doctrine, rather than offering the fundamental, philosophical statement of power dynamics characteristic of Morgenthau’s Classical Realism.

The incorrect option is 3:

John W. Gaddis is arguably the foremost historian of the Cold War, celebrated for his works like *The Cold War: A New History* and *Strategies of Containment*. Gaddis analyzed the dynamics of the Cold War extensively, including the roles of nuclear weapons and détente, often aligning with the "long peace" argument that mutual deterrence prevented large-scale war. However, as an eminent historian who interprets and synthesizes political theory and events, he is not the political theorist who is credited with formulating this specific statement of Realist dogma regarding the relationship between nuclear balance and détente. His academic contribution lies in historical narrative and strategic analysis, not the direct authorship of this foundational Realist axiom.

The incorrect option is 4:

George C. Marshall was an American military leader and statesman, famous for his role as Chief of Staff during World War II and as Secretary of State thereafter. His greatest political legacy is the Marshall Plan, an initiative focused on the economic recovery of Western Europe following the war. Marshall’s contributions were strategic, military, and diplomatic, concentrating on rebuilding global stability and preventing the spread of communism through economic means. He predates the mainstream academic debate over détente and the nuclear balance of the 1970s and 1980s, making it chronologically and contextually impossible for him to have made this statement rooted in Cold War political theory.
