Richard Clarke says US built Stuxnet, blew up centrifuges

“I think it’s pretty clear that the United States government did the Stuxnet attack,” says Richard Clarke, the ex-head of US counterterrorism under three presidents.   The writer wrongly asserts that Natanz is producing weapons-grade uranium in a weapons programme.  Clarke worries that the virus did not self-destruct as planned, and will blow back badly on the US.

“I think it’s pretty clear that the United States government did the Stuxnet attack,” he said calmly.This is a fairly astonishing statement from someone in his position.“Alone or with Israel?” I asked.“I think there was some minor Israeli role in it. Israel might have provided a test bed, for example. But I think that the U.S. government did the attack and I think that the attack proved what I was saying in the book [which came out before the attack was known], which is that you can cause real devices—real hardware in the world, in real space, not cyberspace—to blow up.”Isn’t Clarke coming right out and saying we committed an act of undeclared war?“If we went in with a drone and knocked out a thousand centrifuges, that’s an act of war,” I said. “But if we go in with Stuxnet and knock out a thousand centrifuges, what’s that?”“Well,” Clarke replied evenly, “it’s a covert action. And the U.S. government has, ever since the end of World War II, before then, engaged in covert action. If the United States government did Stuxnet, it was under a covert action, I think, issued by the president under his powers under the Intelligence Act. Now when is an act of war an act of war and when is it a covert action?“That’s a legal issue. In U.S. law, it’s a covert action when the president says it’s a covert action. I think if you’re on the receiving end of the covert action, it’s an act of war.”When I e-mailed the White House for comment, I received this reply: “You are probably aware that we don’t comment on classified intelligence matters.” Not a denial. But certainly not a confirmation. So what does Clarke base his conclusion on?

Stuxnet is a digital ghost, countless lines of code crafted with such genius that it was able to worm its way into Iran’s nuclear fuel enrichment facility in Natanz, Iran, where gas centrifuges spin like whirling dervishes, separating bomb-grade uranium-235 isotopes from the more plentiful U-238. Stuxnet seized the controls of the machine running the centrifuges and in a delicate, invisible operation, desynchronized the speeds at which the centrifuges spun, causing nearly a thousand of them to seize up, crash and otherwise self-destruct. The Natanz facility was temporarily shut down, and Iran’s attempt to obtain enough U-235 to build a nuclear weapon was delayed by what experts estimate was months or even years.
