When focused on these objections

"Yet legitimate complaints that Israeli aggression against Gaza has been disproportionate or is counter-productive are not effective rebuttals to the Israeli government’s self-justifications. In fact, these lines of argument presuppose that Israel was, at least in part, justified in its “defensive security operation”. When focused on these objections, the dispute revolves around the numbers of Palestinian civilians Israel would have been “justified” in killing." (thanks Nimer)
