In Clark Clifford Remembers, his post Tet questions (1968,1969), he draws the conclusion that military action alone will never end the war in South Vietnam. A Task Force was assigned to assess how the military would provide 206,000 more troops to Vietnam. Clifford was part of the task force since he succeeded Robert McNamara as Secretary of Defense for the United States. Cliffored asked questions to which the answers were not encouraging and even down trodden.
"Will 200,000 more men do the job? I found no assurrance that they would."
"Can the enemy respond with a build up of his own? He could and probably would."
These questions and more were asked and poorly answered by the very people handling the war. During 1967 almost 100,000 North Vietnamese traveled to South Vietnam to fight us. General Westmoreland had requested the increase in troops and after Cliffords analysis of the situation in Vietnam he denied Westmorelands request. He was unable to determine when the war would end, how many more troops would be needed along with supplies.
"I was convined that the military course we were persuing was not only endless, but hopeless."
After four years of bombing, fighting and life lost on both ends of the battle the only pragmatic solution would be gradual disengagement. This was the conclusion of the U.S. Secreatary of Defense, Clark Clifford. Yet we didn't start taking our troops out until some years later. So many stuck on the idea that the war could be won----eventually.
