Israel has the right to defend themselves. Yes, civilian casualties are very unfortunate and sad but it happens in all wars and on all sides. I wish they are more careful with that but flip flop terrorists hiding behind civilians doesn't help.
Israel is first line of defense for Europe. They are fighting for whole continent indirectly. Didn't see much being done after all those attacks in Paris, Belgium, London, Manchester... Even people of Lebanon and Syria and region should be thanking Isreal and in grand scheme of things they will because Israel will liberate them and give them a chance for fresh start without these organizations running their countries. In fact, intellectual and democratic people there already know who their real enemy is. I feel such a awe for Isreal and Jewish people. There, I said it. Unpopular opinion but I'm sure future president of USA has exactly the same one.
