Secretary of Defense Donald Rumsfeld asks officers at the Pentagon what else they think the terrorists might do and General Richard Myers, vice chairman of the Joint Chiefs of Staff, suggests they could conduct an attack using weapons of mass destruction. [Myers and McConnell, 2009, pp. 156; George C. Marshall European Center for Security Studies, 8/3/2012; Graff, 2019, pp. 302] Myers has been in the National Military Command Center (NMCC) at the Pentagon since around 9:58 a.m. (see (9:58 a.m.) September 11, 2001) and Rumsfeld has been there since around 10:30 a.m. (see (10:30 a.m.) September 11, 2001). [US Department of Defense, 9/11/2001 ; 9/11 Commission, 7/24/2004, pp. 38, 43-44] Since 11:00 a.m., the two men were with other senior officials in the Joint Chiefs of Staff conference room within the NMCC, participating in a teleconference with other government agencies (see (11:00 a.m.) September 11, 2001). [Historical Office, Office of the Secretary of Defense, 4/9/2003
; Myers and McConnell, 2009, pp. 155] That meeting has now been adjourned and they start making their way back to the deputy director for operations’ office within the NMCC along with Colonel Matthew Klimow, Myers’s executive assistant. Suddenly Rumsfeld stops Myers and Klimow in their tracks. Then, in a command voice, he calls out to the dozen or so officers in the room: “What haven’t we thought of yet? What else can the enemy do?” He “was thinking ahead, engaging in [his] well-known outside-the-box speculation,” Myers will later comment. “He was always challenging his staff to think out of the box,” Klimow will say. Immediately, Myers replies, “NBC,” meaning a nuclear, biological, or chemical attack. Apparently as a result of this interaction, Myers orders that special response units be positioned outside Washington, DC, and New York, presumably in case a nuclear, biological, or chemical attack should occur in one of these cities. It is unclear exactly when the interaction occurs. However, in his 2009 memoir, Myers will place it before midday, when Vice Admiral Tom Wilson, director of the Defense Intelligence Agency, confirms to him and his colleagues in the NMCC that today’s attacks have undoubtedly been committed by al-Qaeda (see 12:00 p.m. September 11, 2001). Klimow will explain why he considers Rumsfeld’s question about what else the terrorists might do to have been “significant in terms of lessons learned.” Rumsfeld was simply saying words to the effect of: “Wake up! Wake up! What else can happen?” But, Klimow will comment, “Somebody needed to do it and they needed to do it right at that moment.” [Myers and McConnell, 2009, pp. 156; George C.
