“The Absolute Weapon”

Bernard Brodie, The Absolute Weapon, 1946

Page 13: Strategy and Nuclear Weapons

First Nuclear Age, 1945-90s

1. Bipolarity– balance

2. Deterrence– vulnerability

3. Arms Control– Managing rivalry

4. Rationality

Second Nuclear Age, 1990s to present

1. Multipolarity– asymmetry

2. Deterrence– missile defense

3. Arms Control– coercion

4. Rationality

First Nuclear Age 1945-90s

1. Bipolarity– balance

2. Deterrence– vulnerability

3. Arms Control– Managing rivalry

4. Rationality

Page 15: Strategy and Nuclear Weapons

1. Bipolarity• An Arms Race– Spiral theory

• US and USSR rough equality• Balance of power• Triad– ICBMs– SLBMs– Bombers

Two Arms Races by 1960s

1. Offense-offense2. Offense-defense

Early ABM Systems

• Johnson Administration: “Sentinel”

2. Deterrence

Strategies of Deterrence1.Warfighting– JFK: Flexible Response– Nixon: Limited Nuclear Options: NSDM-242– Carter: Countervailing Strategy: PD-59– Reagan: Prevailing Strategy: NSDD-13

Strategies of Deterrence2. Assured DestructionDeterrence = Second Strike capability• “Balance of Terror” – Albert Wohlstetter, Foreign Affairs, Vol. 37, No. 2

(January 1959): 211-234

3. Arms Control

• Management of the arms race• Cut costs• Increase predictability• Increase transparency• “Essential equivalence”
