Top FBI official warns 9/11 is still inspiring terrorists inside America 25 years later

Quarter-Century After 9/11, FBI Says the Terror Threat Has Shifted Shape, Not Disappeared

Tyunews.com – Twenty-five years have passed since al-Qaeda sent planes into the World Trade Center and the Pentagon, killing nearly 3,000 people in a single morning. Yet federal law-enforcement leaders insist the danger has not faded with the anniversary. Instead, they argue, the threat has mutated into something harder to see: individuals radicalized in their own living rooms, recruited through screens rather than foreign training camps, and now operating inside American cities with fewer visible markers than the plots of 2001.

Radicalization at Home, Detection Under Pressure

Chris Raia, the FBI’s co-deputy director, framed the current challenge in blunt terms during an interview. He explained that the bureau now watches people who never set foot in a conflict zone yet absorb extremist messaging through social platforms and online forums.

“We see people getting radicalized from the comforts of their own home, through social media, the internet. Those are the folks that keep me up at night because it’s just so much harder for us to detect those.”

The distinction matters for public understanding. In 2001, the FBI was tracking a coordinated, multi-city operation involving hijacked commercial aircraft. Today, the agency says its primary worry is the isolated individual — what Raia calls a “lone offender” — who may plan an attack with little organizational scaffolding behind them.

A Better-Resourced Bureau, a More Adaptable Enemy

Raia acknowledged that the FBI and the broader intelligence community are structurally stronger than they were two decades ago. New legislation, expanded analytical tools, and lessons learned from post-9/11 reforms have, in his words, left the bureau in a markedly improved posture.

“Way better postured now in 2026, based on legislation, based on how far we’ve come in the [FBI] bureau, based on how far we’ve come in the U.S. intelligence community.”

He cautioned, however, that foreign terrorist organizations have proven “adaptable” and “agile.” Al-Qaeda and ISIS, once dominant battlefield forces, now lean heavily on digital outreach to cultivate sympathizers in the West while quietly rebuilding their ranks abroad. A March report from the U.S. intelligence community noted that ISIS membership has climbed to roughly 18,000 worldwide, while al-Qaeda’s network reaches an estimated 28,000 members — figures that suggest the organizations are far from defunct even if their conventional military footprint has shrunk.

Arrests Signal an Active Domestic Pipeline

Over the past eighteen months, the FBI has made at least 16 arrests inside the United States of individuals accused of plotting or supporting plots to kill Americans on behalf of al-Qaeda or ISIS. Officials describe these cases as evidence that the radicalization-to-action pipeline remains open and that detection, while difficult, is still possible.

One recent case drew particular attention. In late August, agents took into custody Jessica Bowie, a 35-year-old resident of Albany, New York, on charges that she plotted to bomb the state capitol building. Charging documents revealed that in the weeks before her arrest, Bowie posted on social media: “Praise be to Allah for September 11th.”

Craig Tremaroli, who heads the FBI’s Albany field office, offered a pointed observation at the post-arrest press conference. He noted that Bowie had allegedly

“gone from a little girl waving the American flag after 9/11 to now having stickers of the fallen towers.”

“Let that sink in,” Tremaroli added. Bowie has not yet entered a plea.

9/11 as an Enduring Symbol in Extremist Messaging

Raia emphasized that the anniversary itself remains a rallying point for online recruiters. When agents examine the media and communications of suspects, references to September 11, 2001, appear repeatedly.

“That is their Super Bowl. Every time you start digging into their media, digging into their communications, there’s always, always references to 9/11.”

The persistence of that symbol underscores why the anniversary continues to carry weight beyond memorial ceremonies: it functions as a narrative anchor for groups seeking to frame American life as perpetually indebted to, or at war with, the events of that morning.

Drones, Immigration Questions, and Resource Debates

Looking ahead, Raia identified unmanned aerial systems as a growing priority. He argued that drone-based attacks remain a plausible vector for future plots and that the bureau is working to stay ahead of that capability.

“Drones has really been forefront of my priorities. You would be silly to think that that’s not coming to the United States at some point, and we are trying to stay ahead of that.”

He also pushed back against criticism that the FBI’s attention has been diverted by immigration-enforcement tasks under the current administration. Raia characterized the bureau’s immigration footprint as “very minimal” and stressed that counterterrorism remains among its top operational priorities, with adequate staffing and budget to sustain that focus.

The Public’s Role Remains Central

Despite expanded surveillance tools and analytical capacity, Raia returned to a principle the bureau has promoted since shortly after 2001: ordinary citizens are still the first line of detection. Neighbors, coworkers, and transit riders who notice unusual behavior and report it continue to provide intelligence that no satellite or algorithm can replicate.

“See something, say something. That campaign that started 20-something years ago, that is just as important today in 2026, if not more important than it was in 2001.”

As the nation marks another anniversary of the attacks, the message from the bureau is clear: the threat landscape has changed, the tools have improved, but vigilance — both institutional and civic — remains the operative safeguard.
