Review by Henry Kissinger.

Acheson treated diplomacy as the more or less automatic consequence of a strategic deployment; Kennan saw it as an autonomous enterprise depending largely on diplomatic skill. The danger of the Acheson approach has been stagnation and gradual public disenchantment with stalemate. The danger of the Kennan approach has been that diplomacy might become a technical exercise in splitting differences and thus shade into appeasement. How to merge the two strands so that military force and diplomacy are mutually supportive and so that national strategy becomes a seamless web is the essence of a continuing national controversy.
