As I just stated, I believe that the goals of the Neocons are consistent with the goals of hardline Israelis, so it wouldn't surprise me if they helped each other achieve their goals. If the Neocon goals are in the best interest of the US, then it's not a bad thing; but I don't believe they are.
Yes, I am absolutely guilty of posting articles about the battles between the Neocon-controlled Pentagon and the State Dept or the CIA. That tells me there are people who in those agencies who also believe that the interests of the Neocons are not in the best interests of the US.
As for spies, Israel would never infiltrate US security agencies, would they?
