For 60+ years Israeli civilians have been systematically targeted and murdered by enemy whose objective was to kill as much as Jews as possible. While chief rabbi talks about no mercy to enemy,the other side has been not just talking,but also practising it since 1948 even if that meant to kill a child or woman so who can be really surprised that Arab bestialities have created this kind of show no mercy to enemy responses in Israel? Still better than Egyptian Cleric Muhammad Hussein Ya?qoub's The Jews Are the Enemies of Muslims Regardless of the Occupation of Palestine. http://www.memritv.org/clip/en/2042.htm
