Americans marked the 25th anniversary of the September 11 attacks on Friday. Newly declassified documents revealed warnings U.S. intelligence officials had received years before the event. A 1998 intelligence brief highlighted Osama bin Laden’s preference to target the US in Washington and suggested that al-Qaeda might fly an explosive-packed airplane into a U.S. city.
The CIA released 71 declassified President’s Daily Brief products, showcasing intelligence on bin Laden and al-Qaeda prior to September 11. CIA Director John Ratcliffe described the disclosure as an exceptional act of transparency, opening a window into past intelligence concerns.
Several documents indicate that discussions about potential attacks against the U.S. and aircraft use had emerged well before September 11.
In July 1998, officials speculated that bin Laden prioritized attacks in the U.S., including interest in chemical and biological weapons. By December of the same year, a brief mentioned hijacking threats and security evasion during trial runs at a New York airport. The brief also noted some members of bin Laden’s network had received hijacking training.
Other documents detailed bin Laden’s quest for materials to make dirty bombs, which are conventional weapons filled with radioactive material. By June 1999, it was reported that operatives had experimented with explosives to enhance energy output.
Briefs from early 2001, prepared for President George W. Bush, also touched on bin Laden’s experimental efforts to create biological agents.
As September 11 drew near, warnings persisted. A report from a month before the attacks reiterated bin Laden’s commitment to conduct U.S. terrorist acts. It highlighted that past al-Qaeda attacks showed preparation years in advance and resilience despite setbacks.
The August 2001 brief reported suspicious activity like surveillance of federal buildings in New York, aligning with hijacking or other attack preparation. It noted the FBI was investigating roughly 70 cases tied to bin Laden domestically.
The newly released documents do not show foreknowledge of the September 11 plot. Many brief contents were redacted, excluding source names and identifying information.
The Associated Press noted that the documents did not introduce significant new insights into attack planning or officials’ understanding of events as they unfolded.
Nearly 3,000 individuals were killed on September 11, 2001, when 19 al-Qaeda terrorists hijacked four aircraft and struck the World Trade Center and Pentagon. A fourth plane, United Airlines Flight 93, crashed in Pennsylvania following passenger and crew intervention.
A report on September 12, 2001, mentioned the attacks were planned for two years and included the U.S. Capitol as a target, according to AP.
Reflections from U.S. Leaders on 9/11
Former President George W. Bush, in office during the attacks, reminisced on learning the U.S. was under attack during an event at the George W. Bush Presidential Center in Dallas. Bush shared he was listening to a child read in a Florida classroom when White House chief of staff Andy Card informed him of the second plane hitting the World Trade Center.
“I didn’t have much time to process that, but it was pretty clear to me that if we were under attack, my job was to defend the child reading to me, her family, and her country,” Bush stated. “And so it was a moment of clarity.”
Condoleezza Rice, Bush’s national security adviser during the attacks, addressed the Pentagon’s anniversary ceremony, reflecting on the September 11 prevention failure.
“Those of us in authority on that day did not see the nature of the danger in time to prevent the attack,” Rice said. “We did what we knew to do, but it was not enough.” Rice expressed remorse for the continued pain felt by victims’ families and the trauma endured by the country.
President Trump observed the 25th anniversary at the Pentagon ceremony, joining First Lady Melania Trump to remember the victims. Trump listened to the names of the 184 Pentagon victims being read aloud, with a bell tolling between each.
Trump recounted several victims’ stories in his remarks.
“Today, we renew the sacred oath we first swore in their names a quarter of a century ago,” Trump remarked. “We will never forget. That’s why we fight today. We don’t have a choice. There can only be victory. We fight hard. We fight to win. We will always remember the victims and the families of September 11, 2001.”
