Of course, it may not fully disband at all, even though it does seem like the beginning of the end. Interestingly, Ha'aretz thinks that Netanyahu is pushing hard right now because, of all things, he thinks a Lieberman indictment (which has supposedly been "close" for well over six months) is finally "imminent," and it would cause Beitenu to leave the coalition.
This is kinda too bad, I was hoping this was as a buttress in the case of a rightist (or Haredi) breakaway from the coalition. The latter would be if my hope of actually getting tough on the Haredim happens; not just the 'insufficiently modest' women-beating, racist (against their fellow ultra-Orthodox Jew, even), Shabbos-rioting "minority", but against the entire non-working, non-serving, unacceptably educating in regard to future employment majority.
Or in the former case, if the peace process starts moving and, say, Habayit Hayehudi and the rightist elements of Beitenu and Likud leave the coalition. Though all of Beitenu might leave if Lieberman wants it, if he gets indicted, the party might split. In that case, maybe Sofa Landver, Danny Ayalon and some others might stay, who knows?
