It may have been intended as an insult; depends on how we take it. If we were to take it at face value, and invite him to send over a white paper, or one of his concerned bureaucrats to make a presentation, what would happen?Why do we need to feel insulted? About what precisely? Is it that we can never receive any advice from others? Is it that we are never to receive advice from Pakistan?
I really don't understand why people are getting insulted. If we feel that the offer was not worth our while to consider, nothing stopped us from saying that we appreciate the offer, but things being well under control, felt no need to avail of it.
