Twenty-five years after the September 11th attacks, a top FBI official is warning that the threat from foreign terrorist organizations remains significant and is evolving in ways that make it harder to detect. Chris Raia, the FBI's co-deputy director, stated that individuals are increasingly radicalized from their homes via social media and the internet, a trend that poses a substantial challenge for law enforcement.
Raia indicated that while the FBI is better equipped in 2026 to counter large-scale, sophisticated plots compared to the 2001 al-Qaeda attacks, terrorist groups like al-Qaeda and ISIS are demonstrating adaptability. These organizations are actively working to foster "lone offenders" within the United States. In the past 18 months, the FBI has apprehended at least 16 individuals in the U.S. suspected of plotting or supporting attacks on behalf of these groups.
An intelligence community report from March noted that ISIS and al-Qaeda, while utilizing social media to reach Americans, are expanding their overseas membership. ISIS is estimated to have up to 18,000 members globally, while al-Qaeda's ranks are believed to be as high as 28,000.
Raia emphasized that 9/11 continues to serve as a powerful motivator for individuals radicalized online. He described references to the attacks as a constant theme in the media and communications of those individuals. As an example, he cited the recent arrest of Jessica Bowie in Albany, New York, who was allegedly planning to bomb the state capitol. Charging documents revealed her social media posts praising Allah for September 11th. A local FBI official noted the stark contrast between Bowie as a child waving an American flag after the attacks and her later fixation on images of the fallen World Trade Center towers.
Addressing concerns about the FBI's focus, Raia refuted criticisms that immigration enforcement has diverted resources from counterterrorism efforts. He asserted that the FBI's involvement in immigration policy is minimal and that combating terrorism remains a top priority with adequate resources.
Raia described the ongoing efforts as a strategic challenge, with the FBI working to anticipate future threats, including the potential use of drones. He stressed the continued importance of public vigilance, reiterating the "See Something, Say Something" campaign, which he believes is as critical today as it was in 2001.
