At moments like this, it’s hard not to think about the Altalena affair. Tragic though it was, it was the defining moment at which Ben-Gurion made it clear to all that there would be one central authority in the Jewish state. Those who sought to subvert it would be treated in accordance with what they were – threats to the state’s very existence. One prays that some progress can be made here without the use of force. But if it cannot, it’s worth remembering that we once had a prime minister who knew what had to be done.
