What did Israel gain by appearing to "go crazy" in Gaza?
The checkpoints have no relation to security of Israel, and if some are intended to safeguard settlers, they are flatly illegal, as the World Court ruled. In reality, their major goal is harass the Palestinian population and to fortify what Israeli peace activist Jeff Halper calls the "matrix of control," designed to make life unbearable for the "two-legged beasts" who will be like "drugged roaches scurrying around in a bottle" if they seek to remain in their homes and land. All of that is fair enough, because they are "like grasshoppers compared to us" so that their heads can be "smashed against the boulders and walls." The terminology is from the highest Israeli political and military leaders, in this case the revered "princes." And the attitudes shape policies.
The ravings of the political and military leaders are mild as compared to the preaching of rabbinical authorities. They are not marginal figures. On the contrary, they are highly influential in the army and in the settler movement, who Zertal and Eldar reveal to be "lords of the land," with enormous impact on policy. Soldiers fighting in northern Gaza were afforded an "inspirational" visit from two leading rabbis, who explained to them that there are no "innocents" in Gaza, so everyone there is a legitimate target, quoting a famous passage from Psalms calling on the Lord to seize the infants of Israel's oppressors and dash them against the rocks. The rabbis were breaking no new ground. A year earlier, the former chief Sephardic rabbi wrote to Prime Minister Olmert, informing him that all civilians in Gaza are collectively guilty for rocket attacks, so that there is "absolutely no moral prohibition against the indiscriminate killing of civilians during a potential massive military offensive on Gaza aimed at stopping the rocket launchings," as the Jerusalem Post reported his ruling. His son, chief rabbi of Safed, elaborated: "If they don't stop after we kill 100, then we must kill a thousand, and if they do not stop after 1,000 then we must kill 10,000. If they still don't stop we must kill 100,000, even a million. Whatever it takes to make them stop."
