For much of the last decade, as Iran methodically built its nuclear program, Israel has been assembling a multibillion-dollar array of high-tech weapons that would allow it to jam, blind, and deafen Tehran's defenses in the case of a pre-emptive aerial strike.Lake has more at the link. Recent news reports have had the Israelis and the U.S. engaged in talks to coordinate efforts in the event that Iran crosses any of several "red lines" that will trigger an attack. Iran, for its part seems determined to see just how much resolve there is in the White House.
A U.S. intelligence assessment this summer, described to The Daily Beast by current and former U.S. intelligence officials, concluded that any Israeli attack on hardened nuclear sites in Iran would go far beyond airstrikes from F-15 and F-16 fighter planes and likely include electronic warfare against Iran’s electric grid, Internet, cellphone network, and emergency frequencies for firemen and police officers.
For example, Israel has developed a weapon capable of mimicking a maintenance cellphone signal that commands a cell network to “sleep,” effectively stopping transmissions, officials confirmed. The Israelis also have jammers capable of creating interference within Iran’s emergency frequencies for first responders.
In a 2007 attack on a suspected nuclear site at al-Kibar, the Syrian military got a taste of this warfare when Israeli planes “spoofed” the country’s air-defense radars, at first making it appear that no jets were in the sky and then in an instant making the radar believe the sky was filled with hundreds of planes.
Israel also likely would exploit a vulnerability that U.S. officials detected two years ago in Iran's big-city electric grids, which are not “air-gapped”—meaning they are connected to the Internet and therefore vulnerable to a Stuxnet-style cyberattack—officials say.
A highly secretive research lab attached to the U.S. joint staff and combatant commands, known as the Joint Warfare Analysis Center (JWAC), discovered the weakness in Iran’s electrical grid in 2009, according to one retired senior military intelligence officer. This source also said the Israelis have the capability to bring a denial-of-service attack to nodes of Iran’s command and control system that rely on the Internet.
Tony Decarbo, the executive officer for JWAC, declined comment for this story. The likely delivery method for the electronic elements of this attack would be an unmanned aerial vehicle the size of a jumbo jet. An earlier version of the bird was called the Heron, the latest version is known as the Eitan. According to the Israeli press, the Eitan can fly for 20 straight hours and carry a payload of one ton. Another version of the drone, however, can fly up to 45 straight hours, according to U.S. and Israeli officials.
It's a dangerous game, but Iran simply cannot be allowed to obtain a nuclear device. It would set off an arms race in the Middle East that would almost certainly result in a proliferation of such devices and also make it extremely likely that one or more will be used, if not by a state entity then certainly by a group like Hezbollah, al Qaeda, or Hamas, any of which will doubtless find someone willing to supply them with a weapon.
