When will Israeli politics grow up?

This isn't a nuanced policy review, nor is it a deep existential exploration. Just a random question I'm throwing into the ether at 2 in the morning; When will Israeli politics grow up?

The nipping and backbiting between Members of Knesset is ridiculously candid and over the top, constantly making appearances in the press. It's embarrassing. In the most recent snap, we have several MKs leaving the Kadima party, and one of them, Eli Afalo, has a big bone to pick with Kadima leader Tzipi Livni. The quote from Jerusalem Post:

"You betrayed me and I don't believe in you anymore," Aflalo told Livni in the heated conversation.

Really, must you be that dramatic Aflalo? And if you must, does it really have to show up in the paper instead of being contained in a closed door conversation between adults?

I guess not - politics is theatre after all. I completely understand that there will be heated inner-party tensions, but I guess Aflalo's line above just seemed more suitable for a soap opera than an MK quotation.

National Security Advisor Uzi Arad recently put his foot in his mouth in speaking about one of his colleagues, but he had the good sense to apologize and clarify his remarks after they leaked out.

I get the feeling that David Ben-Gurion didn't waste his time putting people down. He had better things to do.
