Stuxnet A U.S.-Israeli Joint Effort? The worm itself now appears to have included two major components. One was designed to send Irans nuclear centrifuges spinning wildly out of control. Another seems right out of the movies: The computer program also secretly recorded what normal operations at the nuclear plant looked like, then played those readings back to plant operators, like a pre-recorded security tape in a bank heist, so that it would appear that everything was operating normally while the centrifuges were actually tearing themselves apart. President Obama, first briefed on the program even before taking office, sped it up, according to officials familiar with the administrations Iran strategy. So glad Republicans left this for Obama to do. Could you imagine leaving technological warfare in the hands of Republicans? A political party that doesn't believe in science? A party that sends our technology to China?
