 The JCS then handed the report off to the Commander-in-Chief, Pacific (CINCPAC) Admiral Sharp, who wrote back that the barrier idea was impractical from a manpower and construction point of view.General William Westmoreland, who was commanding officer in Vietnam, was apprehensive of the idea and reportedly was even afraid that the barrier would go into history as "Westmoreland's Folly".Despite all disagreements, on September 15, 1966, without waiting for the final judgment of the JCS, Secretary McNamara ordered that the proposal be implemented.
