Teribus, Several points come to mind, firstly why are you answering a question put to Keith. Do you feel he is not capable of responding himself, do you feel he is inadequate and unable to elucidate intelligently on his own. Secondly I made no reference to Keith's knowledge on the subject of WW1, I merely asked on what authority he considered some historians to be valid but considered other historians to be invalid. Thirdly you have no insight into my knowledge of the subject, he do not know which books I have read or which books have passed me by. So perhaps you will do us all a favour and mind your own business and allow Keith (who you seem to believe is NOT knowledgeable and capable enough) to answer on his own. So Keith what is your authority to declare some historians valid and some historians invalid. PS Take no notice of your mate he seems to believe you are thick.
