"The ultimate guide to decision should be our estimate at the time of the nature and extent of the American interest. There may be good reasons to use our resources to resist a troublemaking power which commits aggression against a weak and friendly state if the subversion of that state would be a significant gain to the troublemaker or a significant loss to us. Even then, we should have a reasonably accurate and encouraging estimate of the chances of success before we act. We cannot afford to stake our world standing on a lost cause or on one with unduly high risks of failure."

“The acceptance of the legitimacy of the overt use of power comes hard in some segments of our citizenship. In some of the expressions of concern over our behavior in Vietnam, we are seeing curious aspects of our national character in this regard. They often contain a note of reluctance or of regret over the use of the vast power represented by the resources of the United States at home and abroad. In some quarters there seems to even be what amounts to a certain feeling of guilt arising from our possession of this power and an uneasiness about the morality of our conduct. One consequence of this attitude in the Vietnam situation is that our government must constantly defend its actions to critics and, in so doing, is often obliged to disclose its plans and purposes to a degree which must be vastly helpful to our opponents. Inevitably in a situation such as Vietnam, where we are using limited means to gain limited ends, it is essential to keep the adversary in doubt with regard to the full scope of our intentions.”

“I have been among the officers who have said that a large land war in Asia is the last thing we should undertake. Most of us, when we use that term, are thinking about getting into a land war against Red China. That's the only power in Asia which would require us to use forces in very large numbers. I was slow in joining with those who recommended the introduction of ground forces in South Vietnam. But it became perfectly clear that because of the rate of infiltration from North Vietnam to South Vietnam something had to be done.”

“Both of these alternatives would have the disadvantage of depriving Congress of responsible military advice needed to discharge its constitutional responsibilities toward the armed forces. Each year the matters of national security are becoming increasingly complicated and technical, yet the members of Congress must legislate wisely with respect to them. To whom can they turn other than to the Chiefs of Staff, who are responsible for our national defense? To deprive them of access to the views of the Chiefs of Staff would inevitably force them to seek irresponsible sources of advice, to the probable detriment of their legislative actions.”

“As we jumped from our plane, as far as one could see were parachutes of many colors floating gently to earth in the warm afternoon sunshine. In contrast to the scattered drop in Normandy, there were no lonely officers roaming about looking for their units- the fields were alive with American soldiers assembling their equipment and hurrying to the rendezvous points of their companies.”

“A recruit arriving in a new unit feels lonely, homesick, and insecure. Someone has to welcome him when he arrives and make him understand that he is truly wanted. That responsibility is shared by every officer in the channel of command, beginning with the division commander. I made it a point to try to meet every new soldier joining the Division, usually assembling them in small groups for a handshake and an informal talk. A standard question for a new man was why he had volunteered for parachuting and whether he enjoyed it. On one occasion, a bright-eyed recruit startled me by replying to the latter question with a resounding "No, sir." "Why, then, if you don't like jumping did you volunteer to be a parachutist?" I asked. "Sir, I like to be with people who do like to jump," was the reply. I shook his hand vigorously and assured him that there were at least two of us of the same mind in the Division.”

“Of course, the media did not have to manufacture dissent and antiwar feeling in the United States; there was enough of the real article to provide them with legitimate subject matter. Every war critic capable of producing a headline contributed, in proportion to his eminence, some comfort if not aid to the enemy. Unfortunately, from 1967 onward there was no shortage of eminent figures among the opponents of the war willing to make this contribution.”
