It would have been best to have an international commission with an Israeli, a Turk, and two neutral/foreign members that Israel and Turkey would agree on. This should have been arranged in negotiations between Israel and Turkey. A majority vote would have meant 3:1, a convincing majority with the two neutrals probably agreeing. Such an arrangement would have improved the relationship between Turkey and Israel, while a strictly Israeli commission will only create more distrust. Unfortunately, Israeli paranoia precluded this from happening. I hope the UN pushes for such an arrangement.
