Historical evidence and sources are vital for the present and future generations to visualize and understand the past. Therefore, if our leaders of today choose to recreate history by eliminating evidence or information( to tell it how they want you to see it), then history is not really history. Primary source can be more accurate than secondary source but despite which one is more correct, they both are interpreted from a point of view which allows space for bias. Nevertheless, when researching history one must review and select  reliable evidence and sources. Then after, link them to come up with a concrete view.
