If you're trying to ethnically cleanse an area, your best weapon isn't a gun, a tank or a helicopter. It's a Caterpillar bulldozer, specifically the armored D-9 bulldozer now being expertly wielded by the Israeli Defense Forces in destroying the homes and infrastructure of the Palestinians (some good pictures of the results, although of course it is difficult to photograph the results of sickness caused by destruction of the water supply by intentionally destroying water pipes). One particularly intrepid D-9 bulldozer driver has apparently become a sort of folk hero in Israel. Some spoilsports are even suggesting that we boycott Caterpillar until it agrees to stop selling these toys to the IDF.
