Unlike in democratic states the Israeli politician doesn't serve the people they serve themselves. Olmert a Prime example. The use of scarecrows by Israeli politicians enables them to either delay, hide or cancel decisions that should be made for the good of Israel, but which the Israeli politician is unwilling or unable to make as it will make them unpopular. And as Olmert is alleged to have done, being a politician in Israel is a very lucrative business. Shalit being the casing point, Netanyahu knows what he has to do to gain Shalit's release, hence the term blood on their hands, he is not prepared to release Palestinians including Marwan Barghouti, often termed Palestine's Nelson Mandela. Yet he is releasing senior HAMAS politicians on the quiet who were originally put into administrative detention to ensure the release of Shalit. Then you have the Israeli election campaign, netanyahu's central pledge, social reform, health reform, prehaps financial reform. You would have thought they would have been up there. Nope the central pledge of Netanyahu when he came second to Livni was a proposal to attack Iran militarily. The ultimate scarecrow. Livni and Barack attacked Gaza then prolonged the attack when their poll ratings improved.
