Second Wave: Inside Al Qaeda's Post-9/11 Attack Plan and America's Secret Effort to Stop It
A deadlier sequel to 9/11—and the race inside the CIA, FBI, and pentagon to stop it.
In 2003, US intelligence uncovered evidence that al Qaeda had acquired nuclear materials, plotting to smuggle them into American ports. The “Second Wave” threat triggered one of the most urgent and secretive manhunts in US history.
With the cinematic intensity of Zero Dark Thirty and the investigative depth of The Looming Tower, Michael Lebowitz captures post-9/11 chaos and agents risking everything to prevent another catastrophe, families torn apart, and the ethical fault lines still dividing US intelligence.
Readers meet Pakistani-American industrialist Saifullah Paracha, whose import- export business concealed ties to al Qaeda; Khalid Sheikh Mohammed, architect of 9/11; Majid Khan, a Baltimore gas-station clerk turned jihadist who mapped US targets; an FBI interrogator who broke suspects faster than any waterboard; and an Orthodox Jewish garment importer whose betrayal helped avert disaster. On the 25th anniversary of 9/11, Lebowitz’s account reveals a global pursuit that tested America’s moral limits and Are we as prepared today as we were then?

About the author
Michael Lebowitz
2 books1 followerMike Lebowitz is one of the few American war crimes prosecutors who also has experience capturing terrorists as part of an elite Army unit. For almost nine years, he served as a prosecutor in the controversial Guantanamo Bay military commissions where he became an expert on the 9/11 attacks. Based on his institutional knowledge and expertise, Pentagon leadership selected him to be a special counsel for Guantanamo Bay matters. He is the only war crimes prosecutor to appear in a courtroom for the three major contested cases held at Guantanamo Bay: The 9/11 case, the USS Cole case, and a case against al Qaeda’s top commander in Afghanistan.
These positions afforded Lebowitz unique access at all levels to the world of national security and war crimes. As a combat veteran who served in a U.S. Army Pathfinder unit, he was one of the few war crimes prosecutors to have a combat badge on his uniform. Lebowitz until recently was a senior attorney for the U.S. Department of Justice’s National Security Division, practiced before the Foreign Intelligence Surveillance Court, and was a Special Assistant United States Attorney in the Eastern District of Virginia. He also served as a senior legal advisor to U.S. Army Cyber Command as an officer in the U.S. Army Reserve. He has extensive cyber law experience and has written extensively on quantum computing. Previously, Lebowitz worked at a non-governmental organization in Uganda and was a reporter for the Jerusalem Post, Israel’s English-language newspaper of record. Academically, his work as a national security expert has been published in several legal journals. Lebowitz also has been quoted by media outlets such as the Washington Post, NPR, Associated Press, Wall Street Journal and the Military Times. He also has appeared on various national security podcasts.
Growing up in Cleveland (and suffering through years of sports fan misery), Lebowitz earned his law degree from Case Western Reserve University’s School of Law in 2003 and a journalism degree from Kent State University in 1999. In law school, Lebowitz was a contributing editor for the Case Western Reserve University Journal of International Law. At Kent State, he served as the editor-in-chief of the Daily Kent Stater, the independent, student-run newspaper. As an Army Reserve Lieutenant Colonel, he is currently working on a Master’s degree in Strategic Studies from the Army War College.

Dave's Summary
After 9/11, US officials feared al Qaeda wasn't finished. They believed the group wanted nuclear or radioactive weapons for a second, bigger attack. Investigators called this plan the Second Wave. Khalid Sheikh Mohammad, the mastermind of 9/11, kept pushing for new attacks even after he was caught. He worked with a Pakistani businessman named Saifullah Paracha, whose shipping company could smuggle explosives into US ports. Agents also tracked Paracha's son Uzair. They also followed Majid Khan, an operative who planned to hit gas stations on the East Coast. FBI agent Janelle Miller pieced together the family's ties to al Qaeda through patient work and hard proof. The book draws on interviews and court cases that revealed details of the plot. It shows how close the country came to another huge attack. My takeaway is that a thin line separates safety from disaster. The author, a former federal prosecutor, warns that many post-9/11 defenses have grown weak in recent years. He argues that threats from al Qaeda and other groups are rising again while public focus has moved elsewhere. The book mixes true crime with an interesting behind-the-scenes account of how government officials investigate such threats.
Key Takeaways
1. After 9/11, intelligence showed bin Laden saw nuclear or radioactive weapons as a religious duty, not just a threat to study. KSM confirmed the group kept chasing this goal even while planning new strikes.
2. Saifullah Paracha, a wealthy Pakistani businessman, allegedly agreed to use his shipping company to smuggle explosives into the US. His son Uzair was later convicted for helping move money tied to al Qaeda.
3. Investigators and lawmakers, including Senator Fritz Hollings, warned for years that US ports were far less protected than airports. A war game simulation showed a single incident could cost tens of billions of dollars.
4. The book details how the CIA used harsh methods, including waterboarding KSM, to try to confirm details about the plot. FBI agent Janelle Miller separately built a case against Uzair Paracha through careful questioning and analysis.
5. The author believes that many defenses built after 9/11 have weakened, while threats from al Qaeda, ISIS, and newer groups keep growing. He compares today's complacency to the warning signs that were ignored before 2001.
Memorable Quotes
Top nuclear scientists joined American officials in fearing the Second Wave. Matthew Bunn, a professor of energy, foreign policy, and national security at Harvard, described the danger this way: “If the terrorists who attacked on September 11 had a crude nuclear bomb on the plane, it wouldn’t have been just the twin towers—the whole lower half of Manhattan could have been turned to rubble and ash, with hundreds of thousands of dead and injured.”
Mark Twain once famously said that “history doesn’t repeat itself, but it often rhymes.” An ominous rhyme of repetition comes to mind when considering our federal policies and lapses of vigilance just prior to 9/11 and similar actions and scenarios now playing out in 2026. Twenty-five years after the surprise attack on the World Trade Center and Pentagon, the US government appears to be falling into the perilous trap of complacency once again.
Recent threat assessments from the intelligence community are using similar language that was used in comparable reports during the 1999–2001 period. The many urgent post-9/11 policies implemented to defend against international terror threats have been scaled back. And the public’s trust in lawful electronic surveillance techniques—often the first line of defense in fending off terrorist plots—has eroded over the years while priorities have shifted.
That FBI report offered several specific recommendations designed to prevent the next major terrorist attack. But recent priority shifts on combating international terrorism directly undercut those recommendations. The US is careening toward a pre-9/11 posture of vulnerability. The following graphic listing some of the FBI Inspector General recommendations illustrates this dichotomy of then and now in terms of lack of preparedness.
The Second Wave story is important in the present context and resonates in several ways. Beyond its historical footprint, it also serves as a warning. A major terrorist attack on the US homeland can certainly happen again. As in 1999 and 2000, the American public and government agencies are focused on other concerns. Lulling ourselves into a sense of security will only encourage international terrorists plotting against our US homeland.
What if the Second Wave “explosives” plot meant nuclear or radiological bombs? It was known that bin Laden and KSM were working to obtain weapons of mass destruction. Pakistan was a newly minted nuclear power. Terrorist sympathies were prevalent within the Pakistani government. Al Qaeda operatives were cultivating relationships with Pakistani officials.
Security measures were subsequently fast-tracked with a focus on nuclear, WMD, biological, and chemical weapons detection. The pace of such reforms may have proceeded much more slowly without the impetus of fears stoked by Saifullah’s interactions with KSM. By all accounts, the ports are still vulnerable to smuggling weapons and explosives into the country. But we are surely more secure now than we were prior to the 2003 scare, although that may be in jeopardy with newly entrenched complacency and misplaced focus hearkening back to pre-9/11 preparedness
international terrorist threats remain a prevalent force. In 2026, the US National Counterterrorism Center (NCTC) listed forty-eight active international terrorist groups. That list includes al Qaeda, ISIS, and numerous offshoots.
A recent article from West Point’s Combating Terrorism Center noted that remnants or offshoots of the Palestinian terrorist group Hamas—which has long plotted against Jewish targets in Europe—may turn their attention to terrorist attacks in the US. Hezbollah or other Iranian proxy groups also may target the US.
