The major point behind this story is that Yisrael Beiteinu is largely composed of nutcases. And that's nothing new. But insofar as cracks are beginning to form in Israel's governing coalition, maybe the government will fall, and they'll have to hold new elections. And maybe the results will enable a new governing coalition that's less prone to massively self-destructive behavior.
Or maybe the new elections will make things worse -- heaven forbid I dare express optimism about anything in this region of the world.
