Based on nothing but your extensive ego, you are suggesting she is deluded

I have suggested no such thing. In fact, of your quote, I specifically said "I have no doubt at all of the veracity of this statement." If I have suggested she is deluded, show me where and I will apologise.

I am asking a question of you. Do you believe that most people believed that they were fighting a just war? Not an historian's opinion. Not anyone else's opinion. Do you, Keith A of Hertford, believe that most people who fought in WW1 believed that they were fighting a just war?
