I welcome an opportunity to briefly examine Walt Rostow's contention that we are at a watershed. I am inclined to accept the generic proposition, although it will become apparent that the premises with which we support the conclusion differ.

Vietnam can well be the last great confrontation of the postwar era if we learn the lessons of Vietnam as well as others of recent years. Vietnam is providing an excellent modern example of the limitations of enormous military power. In another area, the Kennedy round, which was completed some months ago, there is also provided a classic example of the limitations of enormous economic power. If the people of the United States and especially its leadership can profit from the experiences of recent months on the military and economic fronts, then Mr. Rostow's thesis that we are at a watershed should prove valid. If we fail to understand or misinterpret what is happening, then it is possible that Mr. Washburn and the new generation are in for the kind of difficulties that could arise from a major decline in the affluence and influence of the United States. Naturally, every American might selfishly view such a prospect with great concern; I am sufficiently chauvinistic about our nation's potential for good that I view it with alarm for the world as a whole.
