having someone running the largest US Embassy in the world who knows the "lingo" might be to our advantage
That is what the attachés are for.
I have to say I don't have a lot of sympathy for him: ambassador positions are a political game and I am sure he knows that. (That doesn't mean he deserves to be treated like that - assuming we have the full story which I doubt - because nobody does, I am just saying he knew it was a snake when he picked it up).
