As of this writing, the diplomats are settling down at the Hotel Majestic, having settled in at their hotels variously on the Right and Left Bank, and one can hope that Senator Hartke's book is out of date. It is a fierce dove's cry for peace through diplomacy, a diplomacy spurned in 1964 when North Vietnam made overtures but would have required surrender, he says, Hartke analyzes the roots of the struggle, tells how we got in (the discredited Bao Dai period, not later) and defines the nature of our commitment in Vietnam. He surveys the credibility gap, the guerrilla warfare in the South (asserts we would have been able to win if outside aggression were involved), the third war in Vietnam (economic), the cost in men and money, the morality gap, prescribes principles for a peace policy. ""Perhaps the central argument of this book rests upon the fact that a policy of escalation has produced conditions which appear to verify the original justification for that escalation."" Passe, hopefully.
