There is a phrase which comes to mind " You do not defeat THE MONSTER by becoming THE MONSTER " Israel were quite justified to seek retribution after the terrible atrocities committed by Hamas.
Unfortunately as is pointed out Hamas hide behind the civilian population and many innocent people are being killed. The Israeli answer is to blanket bomb the entire areas they believe Hamas to be hiding, surely people this is not right. We must differentiate between the innocent Palestinian people of Gaza and the evil terrorists of Hamas....something I'm afraid the Israeli Military is not doing.
