On February 7, 2002, “The president [Bush] and his national security team met in the Situation Room. [Central Command leader General Tommy] Franks presented the refined Generated Start Plan for war with Iraq. It was the first time Bush saw an actual plan that he could order carried out….Under this plan, war with Iraq would still take 225 days. Franks used the term ’90-45-90,’ meaning 90 days of preparation and force movement…45 days of serious bombing prior to the major ground operations…and it would take another 90 days to complete decisive combat operations to remove the regime. Franks then displayed a chart called ‘Timings,’ broken down by month, which was the earliest he was technically and comfortably be ready to start combat. [Secretary of Defense Donald] Rumsfeld, for the first time, introduced the concept of ‘shock and awe’ to the president. At this point it meant building up so much force and conducting various ‘spiking’ operations and bombing that it might in itself trigger regime change.”
