Maybe it is hasty to say he was involved in the set up of the attack, he could be kowtowing to western pressures which are making it perfectly clear the Palestinians will be returned. The only reason I have reservations about the pressuring is the fact that thus far his military operations since the attack would align with having to get rid of every single tunnel before Gaza could be rebuilt. Saudi Arabia has made it perfectly clear they will not invest in Gaza if there is any chance the Israeli's and Palestinians can keep poking at each other and destroy the progress/plans they have for the area.
