“The Rockefeller Report” on defense policy and strategy is issued promoting the concept of graduated deterrence and flexible response as rational alternatives to massive retaliation. It aims to move U.S. foreign policy away from over-reliance on nuclear weapons to other more flexible strategies including counter-insurgency, which would be elaborated in Vietnam. It also calls for a massive military buildup to counter a perceived (but mistaken) notion of Soviet military superiority. The principal authors of the report are Townsend Hoopes and Henry Kissinger.
