The crack has a name you might recognize: the Israeli security establishment. You know — the folks whose job it is to identify and address threats to Israel's safety. A small but growing group of high-power ex-commanders has been speaking out in media interviews and op-ed essays in the past few days, saying that Netanyahu has got the Iran issue wrong.

It's not yet what you'd call an avalanche of dissent. But against the pro-Netanyahu unanimity among the politicians, coalition and opposition alike, the skepticism emerging from the security community stands out in striking relief. As unanimous as the politicians are in backing the prime minister, the generals and spymasters are nearly as unanimous in questioning him. Generals publicly backing Netanyahu can be counted on — well — one finger.
