Chief military advisor to President Kennedy, Chairman of the Joint Chiefs of Staff, one of the chief architects of the Kennedy-Johnson ""doctrine of Flexible Response,"" General Taylor has previously written The Uncertain Trumpet, here writes from a lecture series at Lehigh. He sets forth the belief that ""one of the most significant political developments in this decade has been the progressive dissolution of the bi-polar nuclear confrontation of the United States and its allies with the Sino-Soviet Communist bloc and its replacement by a multipolar power relationship."" His stated purpose: ""to comment upon the significance of this development and point to some of the consequences"" of this circumstance. He points out that the Communists have clearly indicated that the ""War of Liberation"" is their preferred tool of expansion among emerging nations, reviews the ""War of Liberation"" in South Vietnam and our four-point strategy there (""coherent""), cites the lessons to be gained from our Vietnamese experience. Nevertheless, of Vietnam he says: ""I have no hesitancy in saying that I believe our government did the right thing."" He concludes with proposals to cope with multipolarity.
