As an Israeli citizen I can root for the current coalition to generate enough dismay from within that combined with pressure from without its policies will begin to reform. not enough that Netanyahu was always a hardliner, some elements in his coalition are outlandish to the Israeli public itself. Israel's FM, Lieberman has gained momentum not by Sabras (people who were born in Israel), but by people who immigrated from the former Soviet block, who identify with him as a former immigrant from Moldova and for expressing much of their sentiments.
because many in the Israeli public tried to fend off a government led by Netanyahu, many have withrew their traditional vote for the left, and placed it on the party Kadima which is defined as centrist, Kadima was actually the one elected, but it was Netanyahu who eventually succeeded in forming a coalition.
the fact that Palestinian elements use any disturbance to ignite strife makes it more complicated in the sense that the Israeli government can appeal to the traditional security measures formula.
