What did the declassified documents reveal?

The document is a National Intelligence Estimate on possible changes in the Sino‑Soviet relationship, prepared by the Central Intelligence Agency and dated October twenty‑fifth, nineteen seventy‑three. It appears in the public archive of The Black Vault. This estimate was released through a Freedom of Information Act request, processed under case number 2023‑00123, and made publicly available on the Black Vault website on March twenty‑second, twenty‑twenty‑four. The declassification authority was the Director of Central Intelligence, acting under the authority of Executive Order one ninety‑seven ninety‑four. The estimate begins with its heading: “National Intelligence Estimate – Possible Changes in the Sino‑Soviet Relationship – NIE eleven‑thirteen‑six‑seventy‑three.” It notes that the estimate was submitted by the Director of Central Intelligence and concurred in by the United States Intelligence Board.

War between Moscow and Peking is a possibility, but we rate the odds as low—no higher than one in ten. China, clearly the weaker party, would not attack. The USSR would mainly be deterred by China’s strategic missile capability, however modest; the chance of becoming bogged down in a protracted ground war; concern over the potential impact on its economic relations with the West; and uncertainty as to the nature and scope of United States reactions. Military action against China—particularly a disarming nuclear strike—may continue to have a certain appeal to some Soviet leaders if the United States appeared to move toward an anti‑Soviet alliance with the Chinese. Even in this contingency, however, the counter‑arguments would seem far more compelling. Thus, it is likely that Moscow will hold to a more measured course, one which does not foreclose the possibility of some accommodation over the longer term. The longer the Sino‑Soviet peace is maintained, the better the chances for a…
