What did the declassified documents reveal?

From Declassified, this is a Central Intelligence Agency record detailing intelligence on China's potential intervention in the Korean War. Dated October fourth, nineteen-fifty, this document offers an early, high-level assessment of the Communist Chinese threat and its implications for United States policy. This record is available on vault.fbi.gov and documents2.theblackvault.com. This document was released under the Freedom of Information Act. It was declassified by the Interagency Security Classification Appeals Panel, or I-S-C-A-P, and released on July twenty-fifth, two-thousand-and-one. Its declassification authority was the Central Intelligence Agency. The document begins: Central Intelligence Agency. October fourth, nineteen-fifty. Memorandum for: Mr. Merchant. From: Mr. Clubb. Subject: Chinese Communist Threat of Intervention in Korea. Reference: C-A memorandum of September twenty-seventh, nineteen-fifty, "Chinese Communist Intentions." The following additional thoughts are offered respecting the Chinese Communist threat of intervention in Korea. Note the complete message received from the British Chargé d'Affaires at Peking, as provided by the British Embassy in Washington, that: Chou En-lai summoned Pannikar at zero zero one zero hours local time, October fifth, thus indicating urgency; Chou En-lai referred to "American" armed forces crossing the thirty-eighth; and Chou while stating that Peiping was prepared to accept the Indian Government's position re Korea as set forth by Nehru in his September twenty-sixth press conference, said further that China would accept no settlement of the Korea question to which China was not a party. The Chou En-lai démarche cannot safely be regarded as mere bluff, although one, made after presumed receipt by Mao Tse-tung of message from Nehru stating thirty-eighth parallel would not be crossed until after U-N discussion, and two, designed admirably to support the Soviet resolution in U-N. His démarche must be regarded as having been made with foreknowledge and support of U-S-S-R. The political and military stakes are considerable, and Moscow and Peiping may be prepared to take considerable risks. If China and U-S-S-R are prepared now to accept the danger of clash with U-N in Korea, that means that they are prepared to risk the danger of World War Three, and feel ready to meet that danger, given present comparative military strengths. In such case, we cannot avoid danger either by retreating from it or by surrendering to the Peiping threat: either move would increase, not diminish, the danger inherent in the situation for us. Acceptance of either the Soviet proposition, or the Chou dictum that China must be party to any agreement affecting Korea, would obviously vitiate any arrangements for settlement of the Korean affair and rob the U-N allies of fruits of their effort. The danger offered by North Korea in the first instance would thus continue in being. In the light of all of the circumstances neither…
