During Bush's second term, General James Cartwright, then head of United States Strategic Command, along with other intelligence officials presented Bush with sophisticated code that would act as an offensive cyber weapon. "The goal was to gain access to the Natanz plant's industrial computer controls ... the computer code would invade the specialized computers that command the centrifuges."[1] Collaboration happened with Israel's SIGINT intelligence service, Unit 8200. Israel's involvement was important to the United States because the former had "deep intelligence about operations at Natanz that would be vital to making the cyber attack a success."[1] Additionally, American officials wanted to "dissuade the Israelis from carrying out their own preemptive strike against Iranian nuclear facilities."[1] To prevent a conventional strike, Israel had to be deeply involved in Operation Olympic Games.
