What did the declassified documents reveal?

Declassified. Today we examine a declassified Central Intelligence Agency record from July eleventh, nineteen-fifty, concerning Chinese Nationalist operations against the mainland. This document explores the factors involved in launching an expeditionary force from Formosa, now Taiwan, against mainland China, and its potential impact on the Far East. It is accessible via the Black Vault archives at documents2.theblackvault.com. This six-page document, titled "Chinese Nationalist Operations against the Mainland," was declassified under Executive Order one-two-zero-six-five, Section five, with a declassification date of February twenty-fourth, two-thousand-four. It was originally marked Top Secret. The document opens: "This paper is an attempt to list the factors to be considered in connection with the possible launching from Formosa of a Chinese expeditionary force with limited objectives against the mainland area of China. Owing to the extreme importance which the success or failure of an operation of this nature would have upon the existing situation in the Far East, it is believed that in consideration of it, full use should be made of those agencies of the U.S. Government best able to supply information respecting the factors listed." It then proposes key objectives for such an operation, listing them as: "A. To create a major diversion with respect to Korea, drawing Chinese Communist troops from the north and throwing the Chinese Communists off balance? B. To establish a permanent anti-Communist military force in the mainland of China? C. To prevent Chinese Communist assistance to the Indochinese Communists and/or to increase the security of Hong Kong? D. To establish a coordinated and vigorous guerrilla force within a selected area?" The document notes: "These objectives are not necessarily mutually exclusive. For example, a force whose principal objective was either A, B, or C above might be trained and equipped to break up if need be into guerrilla groups." It then delves into the choice of an area for conducting the operation, stating: "The choice of an area in mainland China for conducting the operation is closely related to the principal objective sought. For example, an operation in north China threatening the Manchuria-Peiping area or the North China-Manchuria communication lines would probably have maximum diversionary effect but minimum possibility of survival as an opposition military force. On the other hand, operations in the south China area would probably have less diversionary effect but maximum effect upon the security of Hong Kong, and the flow of assistance to Indochina, and would probably encounter optimum conditions for survival as a permanent force." It identifies key considerations for area selection: "One. The distribution of Communist forces, the morale of these forces, and the loyalty of their leaders to Peiping. Two. The distribution of anti-Communist guerrilla forces, their effectiveness and the degree to which…
