Is Vladimir Putin mad? Russia’s president has launched a costly and unprovoked war, shocked his own citizens, galvanised Nato, triggered damaging but predictable economic reprisals and threatened a nuclear war that could end civilisation. One has to doubt his grasp on reason.
Doubt is part of the point. In The Strategy of Conflict, written in 1960, the economist Thomas Schelling noted: “It is not a universal advantage in situations of conflict to be inalienably and manifestly rational in decisions and motivation.”
A madman — or a toddler — can get away with certain actions because he cannot be deterred by threats or because his own threats seem more plausible. But Schelling’s point is more subtle than that: you don’t need to be mad to secure these advantages. You just need to persuade your adversaries that you might be.
