Why are there no nuclear wars?

It is not a frequently asked question, and we certainly hope they never happen, but you have not asked yourselves why nuclear wars have not happened? The answer to this disturbing question can be found in Robert Ayson’s book, Thomas Schelling and the Nuclear Age, which explains the ideas of Thomas Schelling, winner of the 2005 Nobel Prize in Economics, who has made significant contributions to the world of strategy and international relations.

In several of his works, Schelling analyses the issue of nuclear armament from the perspective of strategy. His approach is to make international relations, especially military decisions, eminently strategic territory. Lessons can be learned from his contributions for other strategy development and success areas.

According to Schelling, the key concepts to explain the nuclear age are stability and balance of deterrence. The strategy must be aimed at seeking stability between the parties. This is achieved by the balance of deterrence, which is based on two elements: a) a situation in which the disincentives outweigh the incentives for both sides to initiate war; b) it is “stable” when it is reasonably secure against shocks, alarms and disturbances.

Therefore, initiating conflict must be discouraged and unexpected events, such as a surprise attack, must be prevented. Schelling’s lesson in the nuclear age is that the respective incentives and disincentives condition stability.

In his explanation of nuclear strategy, Ayson alludes to Brodie’s work, which provides the key: “Precisely because there is no defence against the atomic bomb, any party, possessing atomic weapons, threatened with attack, has the ability to impose heavy costs on the attacker”.

The state of equilibrium is produced by ‘mutual fear of retaliation’. The costs of all kinds involved in the use of nuclear weapons discourage an attack for fear of a response, in the form of a counterattack, from the other side.

Equilibrium occurs because both sides have disincentives to initiate an attack, and the costs of taking one on by the other side are very high. Special care must be taken to avoid surprise attacks and unexpected situations that can change the equilibrium.

It can be argued that the equilibrium in the nuclear age has aspects that resemble the prisoner’s dilemma. Thus, betrayals by the players have a very high cost for both sides because there is a response rule in the form of a nuclear counterattack. As Poundstone explains, nuclear war would be a case of simultaneous and mutual bombing. As early as 1945, Senator Brien McMahon said: “If there is a nuclear Pearl Harbor, there will not be a jury of statesmen left to study the case” (Poundstone, The Prisoner’s Dilemma).

Schelling’s approach focuses on the role of stability and negotiation in the nuclear age. We could draw some conclusions from his approach: the best strategy is the one that seeks stability, which is guaranteed if the disincentives to conflict are greater than the incentives; the balance of deterrence is produced by fear of retaliation by the other side, which comes at significant cost; the best alternative to an endless arms race is negotiation.

In other words, stability is ensured by the parties’ disincentives to conflict and fear of retaliation, which entails high costs. By discouraging conflict, equilibrium is achieved.

The strategy of conflict

In 1960, the economist Thomas Schelling published his work The Strategy of Conflict with a hitherto unusual approach that opened new horizons. His approach was a new analysis of international relations and other areas, applying game theory methods, a part of Economics that carries out simulations of simple games with two or more participants based on the theory of rational choice.

One of the most interesting points of the book is the conceptual material it leaves  to the reader, which allows for multiple applications. Thus, it describes three types of scenarios: pure conflict, pure cooperation, and conflict/cooperation.

Situations of pure conflict would occur if the interests of the antagonists were completely opposed, only “in the case of war, but of a war tending to the total extermination of the enemy.” Situations of pure cooperation are presented as curious exercises in coordination without communication between the parties. For example, where would you meet someone in Madrid – or London or New York- who has received the same instruction, with whom you cannot communicate. Or imagine that you will win 100 euros if you write down on a piece of paper the way to share it out that matches the other party, where communication is impossible.

Schelling’s message is that most scenarios between human beings are ones of cooperation and conflict where there is a common interest and mutual dependence between the parties. Conflict management is sought with mutually acceptable solutions for mutual interests. Hence, the author concludes that most conflict situations are negotiationable scenarios.

The change brought about by this book is its new approach to strategy as applied to international relations and military issues. Thus, strategy does not refer to “the efficient application of force, but to the exploitation of potential force”. This means that the role of armies has an eminently strategic, rather than a purely combative, significance. On another level, this means that victory does not lie in the hand-to-hand combat of the respective forces, but rather in the expectations of the parties and the possibility of respective influence.

From this perspective, Schelling devotes his attention to the notion of “deterrence” as an important element of international relations. He states that an important distinction must be made here between the application of force and the threat of force. Deterrence relates to the exploitation of potential force. Its purpose is to persuade a potential enemy that it is in its own interest to avoid certain courses of action.

The conclusion is that it is not the use of military force, but the threat – serious and credible – of the use of force that would deter the other side from acting. Here would be the paradox that this theory of deterrence is “a theory of the skillful non-use of military force, for which something more than purely military ingenuity is needed”. That is the way to develop strategy as an art and science and to transform some views on international relations and the role of armies. But it would also have applications in business, politics and even everyday life.

In a passage from his book, Schelling offers a definition of strategy based on several elements:

a) it presupposes the existence of a conflict; b) but assumes a common interest of both adversaries; c) it assumes a rational mode of behaviour; d) it focuses on the fact that what appears to each participant as the best course of action depends on what the other does; e) “strategic behaviour” attempts to influence the other’s decisions by acting on their expectations of how the other’s behaviour relates to their own (Thomas Schelling, The Strategy of Conflict).

How to manage conflict? It seems that this is something we must all deal with in the various spheres of life. In The Strategy of Conflict, Schelling offers a view that was innovative for its time, constructing an analytical framework, based on game theory, to deal with international relations, and at one point he proposes various names for this theory, such as precarious association theory or incomplete antagonism theory.  Perhaps the most successful one is what he called interdependent decision theory. This is the key to the strategy of conflict.
