Yes, I got the same impression from the interview. I looked at one of the FT's other interviews and it seemed to have the same tendency towards poking fun at the interviewee, so maybe they do that with everyone?
But yeah, I've always thought Andrew was naive. Actually, a lot of the members of the royal family come across as naive to me. I watched "The Royal Family at Work" on YouTube and some of them were hilarious...especially the Duke of Gloucester.
He was just so terribly dry and formal and vaguely clueless.
However: I think Andrew and the Queen are two people in the royal family who strike me as being genuinely naive, as in, it's part of their personalities and not just their upbringing. In fact I think naivety is something I think Andrew and Sarah had and still have very much in common. Sometimes when either of them are accused of being patronizing or pompous, I look at them and think they're actually sincere and well-intentioned...just for some reason not very worldly-wise.
I love how in that interview, Andrew comes across as having such a blind dedication to duty. His suitcase-in-the-baggage-compartment-analogy amused me very much. And his naval metaphors. And the fact that he carries around The Art of War everywhere he goes. It's clear that he might have left the Navy, but the Navy hasn't left him.
I know someone in the military who was like this, actually--left the military, tried to do a completely different job, but kept making military references
all the time. Finally he went back to the military.
