Propaganda and PR is fine. Israel has enough people working at it. The problem is that, when pushed too far, the propaganda actually backfires on the propagandists. This happens a lot with Israel. No sense of subtlty. No deft touch. Every tack must be driven with a sledgehammer just to make sure that people notice. Okay, Gaza is full of terrorists, driving terrorist cars and raising terrorist children. Since the terrorist entity is blockaded, they bring their terrorist supplies in through terrorist tunnels. Actually, as you all know, the label "terrorist" is more opinion than fact. Menachem Begin commanded the bombing of the King David Hotel, killing about 100 people. He had British soldiers kidnapped and lynched. Itzhak Shamir commanded the assassination of UN diplomats and officials. Ariel Sharon conspired to murder hundreds of Palestinian women and children at the Sabra and Shatila refugee camps. If you don't call these bloody murderers terrorists, then you have no business calling a tunnel in Gaza a "terrorist tunnel".
