One of the commonly accepted narratives of the Internet is that it was built to survive a nuclear attack. This enrages many of its architects, including Bob Taylor and Larry Roberts, who insistently and repeatedly debunked this origin myth. However, like many of the innovations of the digital age, there were multiple causes and origins. Different players have different perspectives. Some who were higher in the chain of command than Taylor and Roberts, and who have more knowledge of why funding decisions were actually made, have begun to debunk the debunking. Let's try to peel away the layers. There is no doubt that when Paul Baran proposed a packet-switched network in his RAND reports, nuclear survivability was one of his rationales. "It was necessary to have a strategic system that could withstand a first attack and then be able to return the favor in kind," he explained. "The problem was that we didn't have a survivable communications system, and so Soviet missiles aimed at U.S. missiles would take out the entire telephone-communication system."76 That led to an unstable hair-trigger situation; a nation was more likely to launch a preemptive strike if it feared that its communications and ability to respond would not survive an attack. "The origin of packet switching is very much Cold War," he said. "I got very interested in the subject of how the hell you build a reliable command and control system."77 So in 1960 Baran set about devising "a communication network which will allow several hundred major communications stations to talk with one another after an enemy attack."78
