Mutual assured destruction, or mutually assured destruction (MAD), is a doctrine of military strategy and national security policy in which a full-scale use of high-yield weapons of mass destruction by two opposing sides would effectively result in the complete, utter and irrevocable annihilation of both the attacker and the defender, becoming thus a war that has no victory nor any armistice but only effective reciprocal destruction. It is based on the theory of deterrence according to which the deployment, and implicit menace of use, of strong weapons is essential to threaten the enemy in order to prevent the use by said-enemy of the same weapons against oneself. The strategy is effectively a form of Nash equilibrium in which neither side, once armed, has any rational incentive either to initiate a conflict or to disarm (presuming neither side considers self-destruction an acceptable outcome).

Famous quotes containing the words mutual, assured and/or destruction:
“Louise Bryant: I’m sorry if you don’t believe in mutual independence and free love and respect.
Eugene O’Neill: Don’t give me a lot of parlor socialism that you learned in the village. If you were mine, I wouldn’t share you with anybody or anything. It would be just you and me. You’d be at the center of it all. You know it would feel a lot more like love than being left alone with your work.”
—Warren Beatty (b. 1937)
“Since we are assured that the all-wise Creator has observed the most exact proportions of number, weight and measure in the make of all things, the most likely way therefore to get any insight into the nature of those parts of the Creation which come within our observation must in all reason be to number, weigh and measure.”
—Stephen Hales (1677–1761)
“There is an eternal vital correspondence between our blood and the sun: there is an eternal vital correspondence between our nerves and the moon. If we get out of contact and harmony with the sun and moon, then both turn into great dragons of destruction against us.”
—D.H. (David Herbert)
