What did the declassified documents reveal?

The document I am reading is a declassified U‑S intelligence assessment titled “The Role of the Submarine in PRC Naval Strategy,” prepared by the Office of Naval Intelligence and dated September twentieth, nineteen seventy‑four. It is notable because it offers a contemporaneous view of how the United States evaluated China’s emerging submarine force during the Cold War.

This military build‑up was undertaken as a necessary step in the realization of several national objectives. Generally speaking, these national objectives stem from the humiliation of subjection and defeat suffered by the Chinese during the past one hundred and fifty years; a traditional sense of national pride recently nurtured as mainland China begins to be recognized internationally for its potential power, and the Chinese belief that China should play a central role in world affairs.” The report lists three specific objectives: “A.
