Summer 2001: Al-Qaeda Plot Described as Upcoming ‘Hiroshima’ on US Soil

After 9/11, Secretary of State Colin Powell will claim that the Bush administration received a “lot of signs” throughout the summer of 2001 that Islamic militants were plotting US attacks. These include al-Qaeda mentions of an impending “Hiroshima” on US soil. [USA Today, 10/15/2001] The 2002 book The Cell also describes an intercepted al-Qaeda message in the summer of 2001 talking about a “Hiroshima-type” event coming soon. [Miller, Stone, and Mitchell, 2002, pp. 288] So this appears to be a different warning than an intercepted communication in 2000 warning of a “Hiroshima-type event” (see (August 2000)), or perhaps a repeat of that.
