Secretary McNamara said that before we undertook attacks against the North, we certainly had to be prepared to meet threats at the level stated by General Taylor. Mr. McCone agreed with this point, but went on to say that there was a serious question about the effect of major deployments on Communist Chinese reactions. The intelligence community was inclined to the view that the more substantial the deployment, the greater the possible chance of a drastic Communist Chinese reaction. General Taylor commented that under present plans it was not contemplated that we should have deployment of all the potentially necessary forces at the outset. We were thinking along the lines of a brigade to the northern part of South Vietnam, two to three brigades to Thailand, considerable naval deployments, and some alerting of other forces in the U.S. and elsewhere. Even this, however, added up to a significant scale of activity...
Secretary McNamara noted that all this planning was on the basis that a really drastic communist reaction was possible, and was not based on any judgment that it was probable. The best current view was that appropriately limited attacks on the North would not bring in Communist Chinese air or North Vietnam or Communist Chinese ground forces. However, it was still essential that we be prepared against these eventualities.
Ambassador Lodge asked whether the Communist Chinese could not in fact mount almost any number of forces they chose. General Taylor and Admiral Felt said they could not do so and support them to the extent required...Secretary McNamara then went on to say that the possibility of major ground action also led to a serious question of having to use nuclear weapons at some point. Admiral Felt responded emphatically that there was no possible way to hold off the communists on the ground without the use of tactical nuclear weapons, and that it was essential that the commanders be given the freedom to use these as had been assumed under the various plans. He said that without nuclear weapons the ground force requirement was and had always been completely out of reach. General Taylor was more doubtful as to the existence or at least to the degree of the nuclear weapon requirement, and again the point was not really followed up.
Secretary Rusk said that another possibility we must consider would be the Soviets stirring up trouble elsewhere. We should do everything we could to minimize this risk, but it too must be considered. He went on to stress the nuclear question, noting that in the last ten years this had come to include the possibility of a nuclear exchange, with all that this involved.
