What is Orwell’s attitude toward “the mutability of the past”? Do you agree with or object to his tone (or both)?

In Orwell's stories, the ruling class controls all interpretation of the past. The past is written to show cohesion... the ruling classes consolidation of power.... anything else would cause rebellion. The role of government is to leave nothing to chance, thus, the past must be controlled. The ruling class always knows best, "war is the health of the state," enemies must be exterminated. Controlling the past brings credence to the present and cements the ruling class' need for control. Orwell's vision proves his insightfulness and creates a perception of a discipline.... but discipline is only meted out to the few.
