Avigdor Lieberman has a populist appeal. Lieberman is bright, clever, even charming, While there's debate about whether he can fairly be classified a fascist, there's no debating his demagoguery. So what if Lieberman wants a divorce from Israel's Arabs? Most Israeli Jews, even the moderates among them, might wish the same. But in the end, they know the difference between idle wishes and public policy.
