Honestly, shit happens during the war. Yes, the mistakes should be investigated, guilty punished etc., but it is a big picture which is important, not a few incidents that are easy to use for propaganda and internet points.
In my mind there are 3 questions that needs to be answered
is war justified?
what is civilian to military kill ratio (basically to see if civilians are killed without care)
what are the goals of the war, what are post war plans
For the first question, I do not know how anyone with straight face can say that the war is not justified when a neighbor attacks you and purposely and barbarously kills 1300 people and takes about 200 hostages.
For the second quested, it is urban warfare, and if anyone cares to check, the ratio of 10 to 1 (civilian to military) is quite typical. In this war, Israel achieves ratio of better than 2 to 1, which says to me that IDF is really careful not to kill civilians unnecessarily.
It is the question (3) where I have problem with right now. Mostly because it is right wing government in Israel and there is no clear out of war path suggested after Hamas is destroyed. But here we can wait and see. Israel is a democracy and I hope her people will make right decision.
