Here is a product of the 3000 year old accumulated Jewish intelligence:
Cabinet votes Gaza a 'hostile entity'
2 years ago we withdrew from Gaza. Since then, this "entity" has demonstrated non-stop hostility towards Israel, with daily attempts at bombing, shootings, infiltrations and rocket attacks on civilian targets. Meanwhile, we supply them with electricity, water, fuel and food. We also allow their workers to come into Israel for work. Then, if we threaten to stop materially supporting our enemies, we are accused of collective punishment.
The absurdity of this situation is a function of what Richard Dawkins calls "shifting moral zeigeist". Basically, this means that moral standards shift over time. Rights take precedence over responsibilities. During WWII or during the Vietnam War, the US or Britain could firebomb entire areas and kill civilians indiscriminately, who paid the price of the war effort. This same behavior would now be considered unacceptable, among Western powers. Nowadays the "rights" of the individual to safety (in our case the Palestinians) take precedence over the right or responsibility that Israel has to defend its citizens. It is also more important than the Palestinians' responsibility to prevent rockets being forward from their land. So Israel has to equivocate and do pilpul (talmudic back and forth analysis) before even turning off electricity in Gaza.
