On November 27, 1965, the Pentagon declared that if the major operations needed to neutralize North Vietnamese and NLF forces were to succeed, U.S. troop levels in South Vietnam would have to be increased from 120,000 to 400,000. In a series of meetings between Westmoreland and the President held in Honolulu in February 1966, Westmoreland claimed that the U.S. presence had succeeded in preventing the immediate defeat of the South Vietnamese government but that more troops would be necessary if systematic offensive operations were to be conducted. The issue then became in what manner American forces would be used.
