Well, The only way to see what happened is to look backward. One way to look back is with a mirror.
History can not be examined any other way than looking backward.
I agree. History will always be “judged” by those who come later. However, those doing the judging will not have lived through the actual events, so take it for what it is worth.
It is not about “looking back” it is about “JUDGING” people in history from a modern lens, which is judging them not within the context of their own times, but ours. Our context did not exist then and being judgemental from our contest tends to try to rewrite the history that already was, to make it conform to today’s context. Then it is no lonher history, but fictional history conforming to today’s context.
