Those that revise and confound, prevent man from expressing his full nature. They refuse to believe that anyone in history be heroic, be honest or sincere in their intents and convictions of self evident truths because they themselves are none of those things.

Besides, if you knew the truth, you would not listen to their dribble.

So as Orwell observed history revised after it happened, we now, in this time can observed history being revised "as" it happens.

Here is what Orwell said in an interview:

“I remember saying once to Arthur Koestler, ‘History stopped in 1936’, at which he nodded in immediate understanding. We were both thinking of totalitarianism in general, but more particularly of the Spanish civil war. Early in life I have noticed that no event is ever correctly reported in a newspaper, but in Spain, for the first time, I saw newspaper reports which did not bear any relation to the facts, not even the relationship which is implied in an ordinary lie. I saw great battles reported where there had been no fighting, and complete silence where hundreds of men had been killed. I saw troops who had fought bravely denounced as cowards and traitors, and others who had never seen a shot fired hailed as the heroes of imaginary victories; and I saw newspapers in London retailing these lies and eager intellectuals building emotional superstructures over events that had never happened. I saw, in fact, history being written not in terms of what happened but of what ought to have happened according to various ‘party lines’.”
