What did the declassified documents reveal?

Declassified. Today, we examine a Department of State intelligence memorandum from June eighteenth, nineteen-sixty-two, titled "Chinese Communist Troop Movements." This document provides a snapshot of U.S. intelligence assessments regarding military activities in the Taiwan Strait during a period of heightened tension. It is publicly available via The Black Vault at documents2.theblackvault.com. This document was declassified on May tenth, nineteen-ninety-seven, under the authority of Executive Order 12958. It was released from the National Archives and Records Administration, N-A-R-A, after a mandatory declassification review. This ensures the public record reflects the intelligence community's analyses at the time. The memorandum from Roger Hilsman, Director of Intelligence and Research, to the Secretary, states: "Subject: Chinese Communist Troop Movements. I. Chinese Communist Intentions. Reports of additional troop movements over the weekend lead us to take a somewhat more serious view of Chinese Communist intentions than we did initially. In brief, our conclusions are as follows: 1. We still feel that the primary purposes of the reported movements are to deter the Chinese Nationalists from attacking the mainland and to ensure that defenses opposite Taiwan are adequate for all contingencies. 2. However, we are now inclined to believe it is also likely that the Chinese Communists have decided to exploit the troop movements politically by creating a new offshore island crisis. To the Chinese Communists, a new crisis may appear useful for several reasons: to exacerbate the visible strains in relations between the U.S. and Nationalist China; to divert attention from domestic economic difficulties and justify stringent measures at home; and to demonstrate that Peiping’s power and interests are something the world must reckon with. 3. We cannot rule out the possibility that the Chinese Communists are preparing for a sudden, all-out effort to take either or both Quemoy (Kinmen) and Matsu, perhaps utilizing [two lines redacted under exemption B1] equipment not available in nineteen-fifty-eight. However, in the absence of evidence that the Chinese Communists are massing the necessary transport (e.g. motorized junks), we do not think a sudden, all-out attack is either imminent or likely. II. Implications for the U.S. This Chinese Communist military buildup opposite Kinmen and Matsu brings to the forefront not only the problem of the offshore islands themselves but also of Chiang Kai-shek's intentions to 'counterattack' the mainland. A direct confrontation of U.S. and Chinese Nationalist interests seems very likely. If the Chinese Communists attack, the U.S. will be faced with pressure from Chiang, from his friends in Southeast Asia, and from his friends here in the United States to participate in the defense of the islands. A decision will be immediately required on whether or not the attack is a preliminary to an attack on Formosa, as specified in…
