A dissenter from General William Westmoreland's more conventional war strategy, Weyand's experience as a former intelligence officer gave him a sense of the enemy's intentions. He realized that "the key to success in Vietnam was in securing and pacifying the towns and villages of South Vietnam" (Mark Salter, John McCain "Hard Call: The Art of Great Decisions"). Weyand managed to convince a reluctant General Westmoreland to allow him to redeploy troops away from the Cambodian border area closer to Saigon, significantly contributing to making the 1968 Tet Offensive a military catastrophe for North Vietnam.
