Benjamin Netanyahu was a failure as PM, as was Ehud Barak, each for different reasons. From what I have read of Netanyahu, I don't think he has the character and moral fiber to be PM. He may not have embezzled (but who knows?), but he lacks decency and humanity. David Ben-Gurion, Levi Eshkol, even Menahem Begin, in spite of his terrorist past, had all of these necessary qualities. Amir Peretz should go beck to running unions. Tzipi Livni, is untried and inexperienced, in spite of her being FM, and Ami Ayalon is an unknown quantity. Of all the possible candidates, I prefer Meir Sheetrit, who has both the necessary educational and political background and considerable experience on both the municipal and national planes, but he doesn't seem to be a charismatic figure who can draw votes. Israel has a leadership crisis.
