Read the excerpt from "Keynote Address.”Of course, the war in Vietnam must be ended. But it must be ended, as President Johnson said last March, by patient political negotiation rather than through the victorious force of arms, even though this may be unpalatable for those raised in the tradition of glorious military victories. But like our other complex problems, this one must also be solved responsibly. Just as we shun irresponsible calls for total and devastating military victory, so must we guard against the illusion of an instant peace that has no chance of permanence.
