Hastings has only specialised in WW1 recently.
He has only spent about three years immersed in study of original sources to produce his acclaimed History of the lead in and start of the war.

He finds himself in agreement with all the learned professors who have studied the period for their whole working lives.

I think they know even more about it than you.
You are sure, in your absurd, ridiculous arrogance, without one day of study, that you are cleverer than all of them.
I question your judgement.
