Few now believe Netanyahu can change his right-wing spots, but many still wonder whether the Israeli left can exert an influence for good.There is much speculation about whether opposition leader Isaac Herzog, head of the Zionist Union party, can be enticed into Netanyahu's government and encourage it towards peace. But a deeper truth about the Israeli left was exposed this month by the introduction of a draconian terrorism bill.The measure, called "wildly authoritarian" by one Israeli analyst, lets the government define any group it dislikes, including civil ones, as a terrorist organisation. Offering non-material support, such as a "like" on Facebook, could land you three years in jail. "Abetting terror", even unwittingly – say, by selling a car to someone who later carries out an attack – can earn you 30 years.
