Article was pretty light on the details. I thought the new york times did a pretty good job of convincing me it was a joint israel/us op back in january:<p>Israeli Test on Worm Called Crucial in Iran Nuclear Delay<p><a href="http://www.nytimes.com/2011/01/16/world/middleeast/16stuxnet.html?_r=1&ref=stuxnet" rel="nofollow">http://www.nytimes.com/2011/01/16/world/middleeast/16stuxnet...</a><p>(pay special attention to the national laboratory discussion)<p>It doesn't sound like Langner is presenting any proof per-se, but then again it's not something I'd stand up on a chair and prove if I could.
The article had absolutely no new content, this has been the rumor for months, discussed in numerous articles and blogs, and is the obvious speculation that would occur to anyone. HMMM - Someone attacked Iran's nuclear program? Gosh, now who would want to do an awful thing like that!<p>Lacking is any evidence or any reason to be writing a new article stating the same thing one more time.
