Skip the politics, let's get to the tech: The Shahab-3 missiles that Iranian solidiers test-fired today — a blatant bring-it to Israel and America — could land a nuke in Tel Aviv. (The city's startup sector was recently dubbed the world's #8 tech hotspot by CNET, less than 240 milliseconds from Sand Hill Road and believe me, no packet loss from those guys.) The missile is based on North Korea's Nodong-1, an Iranian-funded adaptation of the Soviet Scud missiles that Saddam Hussein's troops lobbed at Israel in the first Gulf War. No, it's not true that these missiles are so old they use vacuum tubes instead of silicon chips. It's not true that their guidance systems are built from American GPS gear, as much as the Valley would like to take credit. What is true is that the Shahab-3's biggest vulnerability — a tendency to tumble out of control on the way down to the target — may have been fixed.
