I wasn't saying for one moment that JN was a paragon of the Nav's art, merely expressing discomfort at the way in which he was being derided, and expressing disagreement with the accusations of arrogance.
As to his qualifications (or otherwise) for being a 'defence expert', better a former junior aircrew officer who flew two frontline tours (in two different roles) who went to war, and even experienced being a PoW than some fascist d1ckhead like Max Hastings or some self aggrandising donkey like Lewis Page, I'da thunk.
And much better than Clarkson, or Charlie and her Dimmocks.
