The Stuxnet worm that has shut down Iran’s nuclear facility at Natanz is one of the most intriguing and brilliant counter terrorist moves anyone has ever pulled off.
The project’s political origins can be found in the last months of the Bush administration. In January 2009, The New York Times reported that
Mr. Bush authorized …..
a covert program to undermine the electrical and computer systems around Natanz, Iran’s major enrichment center.
President Obama, first briefed on the program even before taking office, sped it up, according to officials familiar with the administration’s Iran strategy. So did the Israelis, other officials said.
