Perhaps you remember the quote from 1984 at the end of Fahrenheit 911:
It's not a matter of whether the war is not real or if it is. Victory is not possible. The war is not meant to be won. It is meant to be continuous...The war is waged by the ruling group against its own subjects. And its object is not the victory over either Eurasia or East Asia but to keep the very structure of society intact.
November 19, 1947 memo from Clark Clifford to Harry Truman; Clifford was Truman's White House Counsel, and he wrote this at the point at which the Cold War was just starting to heat up:
There is considerable political advantage to the Administration in its battle with the Kremlin. The worse things get, up to a fairly certain point—real danger of imminent war—the more is there a sense of crisis. In times of crisis, the American citizen tends to back up his President.
