If this was a Mossad operation, it does not bode well for Israel. Too many operatives in hostile territory on one target. The Norway Mistake used only 6 operatives. He was a very valuable asset to Iran and Hamas, and should have been interrogated for days before killing him. He could have been abducted and traded for Shalit Gilad. The day after a Fatah representative intered Gaza for talks w Hamas. It happened shortly after killing of 8 CIA operatives; retaliation agasint Iran. It was done to bolster Abbas and cut off Iran as the following week USA General visits Israel to argue against attacking Iran. If this was an Isreli operation, it was a botch job and very unlike Mossad. The 'tradecraft' for all operatives is the same, the objectives are different by country.
