Secretary of Defense Donald Rumsfeld calls Russian Defense Minister Sergei Ivanov and requests that the Russians call off an exercise their military has been conducting. Since 12:19 p.m., Rumsfeld has been based in the Executive Support Center, on the third floor of the Pentagon (see 12:19 p.m. September 11, 2001). [Goldberg et al., 2007, pp. 131-132] He calls Ivanov, who is in Moscow, sometime after the meeting of the National Security Council convened by President Bush from Offutt Air Force Base, Nebraska—which he participated in—ends (see (3:15 p.m.) September 11, 2001). Ivanov “sounded sad” as the two men discuss the casualties of today’s terrorist attacks, Rumsfeld will later recall. Rumsfeld requests that the Russian military stand down an exercise near Alaska. [Rumsfeld, 2011, pp. 343-344] The Russian Air Force began this major exercise over the North Atlantic, Pacific, and Arctic Oceans yesterday and it was scheduled to last all week (see September 10, 2001). [BBC, 2001, pp. 161; North American Aerospace Defense Command, 9/9/2001; Washington Times, 9/11/2001] “[O]ur forces were understandably sensitive now about any intrusions into American airspace,” Rumsfeld will comment, and, he will add, “I didn’t want problems to arise inadvertently between our two countries.” [Rumsfeld, 2011, pp. 344] Ivanov says the Russian military is immediately canceling the exercise. [Myers and McConnell, 2009, pp. 160] The exercise was in fact canceled this morning, according to some accounts (see (After 10:03 a.m.) September11, 2001), and Russian President Vladimir Putin promptly informed the US government of this when he spoke to National Security Adviser Condoleezza Rice over the phone (see Between 10:32 a.m. and 11:45 a.m. September 11, 2001). [Washington Post, 1/27/2002; Baker and Glasser, 2005, pp. 122; Defense Video and Imagery Distribution System, 9/8/2011] Ivanov also promises “solidarity” and Russian cooperation with the US during the call with Rumsfeld, and recommends a G-8 summit on terrorism.
