1. Wikileaks information says

A 2009 American government cable released Sunday by the WikiLeaks website quotes Defense Minister Ehud Barak as telling visiting American officials that a strike on Iran's nuclear facilities was viable until the end of 2010, but after that "any military solution would result in unacceptable collateral damage."

But that can now be delayed, because

2. Wired reports that

In what appears to be the first confirmation that the Stuxnet malware hit Iran’s Natanz nuclear facility, Iranian President Mahmoud Ahmadinejad said Monday that malicious computer code launched by “enemies” of the state had sabotaged centrifuges used in Iran’s nuclear-enrichment program.

And how! The code was written to slowly change centrifuge speeds, so that nobody would notice until it was too late:

Stuxnet targets only frequency drives from these two companies that are also running at high speeds — between 807 Hz and 1210 Hz.

Frequency-converter drives are used to control the speed of a device. Although it’s not known what device Stuxnet aimed to control, it was designed to vary the speed of the device wildly but intermittently over a span of weeks, suggesting the aim was subtle sabotage meant to ruin a process over time but not in a way that would attract suspicion.

“Using nuclear enrichment as an example, the centrifuges need to spin at a precise speed for long periods of time in order to extract the pure uranium,” Symantec’s Liam O Murchu told Threat Level earlier this month. “If those centrifuges stop to spin at that high speed, then it can disrupt the process of isolating the heavier isotopes in those centrifuges … and the final grade of uranium you would get out would be a lower quality.”

Could this also be why N.K.'s tests have fizzled so nicely?

3. Wired also repeats the earlier news from today about a Bond-esque assassination:

...assassinations on Monday could indicate that whoever targeted Iran felt the malware was insufficient to halt Iran’s nuclear program.

According to news reports, the scientists were targeted in separate but nearly simultaneous car bomb attacks near Shahid Beheshti University. Majid Shahriari and Fereydoun Abbasi, along with their wives, were driving to work when assailants on motorcycles zipped by their vehicles and slapped magnetized explosives to the cars, which were detonated within seconds.

Shahriari, who was head of an unnamed Iranian nuclear program, was killed. Abbasi, a high-ranking Ministry of Defense official who reportedly holds a Ph.D. in nuclear physics, was wounded. Both wives were wounded in the attacks.

Two other Iranian nuclear scientists have been killed in recent years. A senior physics professor at Tehran University was killed in January, when a bomb attached to a motorcycle exploded near his car as he was leaving for work. A second nuclear scientist died in 2007 from gas poisoning.

Ahmadinejad blamed it on the US. The rest of the world yawned.
