Talk in Israel of a military strike on Iranian nuclear facilities has reached a fever pitch. Last week brought the news of an alleged "war plan" leaked to a blogger. This week, a well-informed military correspondent in Jerusalem reported that Israeli Prime Minister Benjamin Netanyahu is "determined" to attack Iran before the U.S. election. Two weeks ago, an outgoing government minister told Israelis to prepare for a war that would last 30 days.
Some analysts dismiss the speculation as an effort to intimidate Iran or put pressure on the U.S. to get tough on Tehran.
David Makovsky of the Washington Institute for Near East Policy has his own contacts in the Israeli leadership. He says there's more going on here than just war talk.
"I think there's a 50-50 chance before the U.S. election of an Israeli strike," he says.
In any case, it's clear there's a lot of war thinking going on in Jerusalem.
The alleged war plan that was recently leaked said an Israeli strike would begin with an unprecedented cyberattack designed to paralyze the Iranian regime and blind it to what was happening on its territory. The Internet, telephones, radio and television transmissions, the electrical grid would all be taken out.
That's an attention grabber: The world has never seen a cyberattack remotely that dramatic.
John Bumgarner, chief technology officer at the U.S. Cyber Consequences Unit, says the plan does make sense, at least in theory.
"Israel has very good cybercapabilities. Some of the best computer scientists in the world come out of the Israeli military and intelligence branch," he says. "Some of the best cybertools that are currently used in the world come out of Israel."
But could the Israelis actually pull off a nationwide cyberattack in Iran? Bumgarner is skeptical.
"Maybe they could carry out the attack against certain nodes in the country, like, you know, Tehran," he says. "But to carry it out across the whole country would be very difficult."
Security analyst Jeffrey Carr, the author of Inside Cyber Warfare, says he doubts the Israelis could even take down Iran's power grid, let alone its entire high-tech sector. A grid, Carr points out, is made up of multiple power plants, each with its own network configuration.
"An attacker has to map out the network before it can plan an attack. The scenario that's been described on this war plan, or whatever you would call this, is just fantasy," he says. "There's no way that anyone could create a piece of software or weaponized malware that could just wipe out multiple power plants and multiple grids with one strike. It's nonsense."
So, some of the war talk in Israel is apparently exaggerated. But this may only reflect the debate going on in the country. Someone could circulate a poorly thought-out scenario to discredit the Netanyahu government's war planning.
Makovsky says the volume and variety of speculation about an Israeli strike on Iran just underscore how seriously the idea is taken. Even apparently outlandish plans, he says, should not be discarded out of hand.
"You're going to see all sorts of things out there, and some of it might be disinformation or psychological warfare. There's no way we're going to know," he says. "The Israelis do pride themselves on, you know, surprise elements that no one is thinking about."
After all, three years ago, Israel and the U.S. joined in the Stuxnet cyberattack against an Iranian nuclear facility in Natanz — a surprise to many.
Seemingly far-fetched war talk could amount to propaganda and little else, but it could also mean an Israeli strike on Iran is around the corner. The decision may not yet be made.
