CIA scrutinized minutely all the acted documents relating to the coup (According J.F.K Library: National Security File, Meetings & Memoranda series, box 317: Meetings on Vietnam, 10/29/63 “We maintained clandestine contact with them throughout the planning and execution of the coup and sought to review their operational plans and proposed new government… For military coup d’état against Ngo Dinh Diem, the US must accept its full share of responsibility”)
The "Buddhist event" on 5/8/63 was just a cause for a CIA well plan to eliminate Ngo family for a broader Americanized war for CIP. CIA's memorandum No OCI-2352/63 on 9/14/63 has enumerated into 3 parts: summery report, judgment and reactions. - (1) We (CIA) have had wide reports from Washington concerning of SVN government's link to NVN. a) Through Pole Ambassador Manelli, Ho Chi Minh has proposed a cease fire to Ngo Dinh Nhu who is considering will be taking placed in 3-4 months approach. b) Dr Tran Kim Tuyen unveiled to Ambassador Lodge that Nhu has believed a negotiation with NVN is a lesser bloodshed and best interest for people of both sides. c) He warned high rank US officials in Saigon that a Manelli-Nhu discussion should be for a treaty with NVN. d) Nhu dare-confirmed to CIA chief in Saigon that he met VC representative in SVN. e) Diem's representative Tran Van Dinh secret trip to New Dehli for a Nhu-Ho meeting expected in 11/63 was prepared and foiled because of the coup. f) French President Charles de Gaulle has proposed a neutral SVN solution. - (2) CIA judgments: We (CIA) have feeling of no broad danger from South-North link but we have had enough proofs of further negotiation will be happened. Keep watching with warrant special. The real danger is not a Diem-Nhu's switching side or surrendering SVN to the Communist but a successful political treaty with Hanoi for national interest. They considered having clues for success and it is better to negotiate with natives than to bend under foreign pressure (US). - (3) Reactions: Potential chance Diem-Nhu will have a final decision for a pacification with North Vietnam should be high if they have thought that US pressures had become so intense than they were backed into a corner. If they have only a choice of whether to abandon their power or being of US political pressure in SVN, their choice should be a Northward negotiation. If they go ahead their plan, coup d'état should be considered by his generals. If people support (surely) a North-South solution, the military and political situations had declined sharply from present levels. With that CIA conclusion, there was no Vietnamese who wanted civil war, was there?
1. They (Diem-Nhu) decided to better choosing either the end of their own primacy or humiliating acceptance of a much greater US voice in the political direction of SVN, in fact, submitting to foreign (US) pressure. This CIA own message has proved Diem-Nhu's apparently patriotism. 2. Is their choice of voluntary ending of power instead of bending under foreign pressure for their country's best interest a bad choice? US controlled their puppet regime for its own interest by Cold War architect Harriman, approved by NSC on 9/21/60. A CIP (Counter Insurgency Plan) the must approved by Kennedy administration on 1/28/60 have readied to confront Soviet's NLF (National Liberation Front in Vietnam, from 12/20/60) on battlefield Vietnam? In reality Kennedy in office 20/January/1961 but the CIP by NSC 9/21/1960, Eisenhower administration
