Arms and influence
Traditionally, Americans have viewed war as an alternative to diplomacy, and military strategy as the science of victory. Today, however, in our world of nuclear weapons, military power is not so much exercised as threatened. It is, Mr. Schelling says, bargaining power, and the exploitation of this power, for good or evil, to preserve peace or to threaten war, is diplomacy - the diplomacy of violence. The author concentrates in this book on the way in which military capabilites - real or imagined - are used, skillfully or clumsily, as bargaining power. He sees the steps taken by the US during the Berlin and Cuban crises as not merely preparations for engagement, but as signals to an enemy, with reports from the adversary's own military intelligence as our most important diplomatic communications.
