Mordechai Vanunu is a traitor and should always be treated as such. He betrayed his oath and nation. He did not endanger anyone as the information he released was at worst embarrassing, not critical or dangerous to Israel or any Israelis. I think it is important to understand that there are different types of classified information and some is extremely dangerous to have revealed and some which is merely embarrassing. Vanunu deserves no respect or sympathy for what he did or how he was punished. He is a traitor and deserves no trust, sympathy or reward.
