The worst terrorist attack in world history occurred on September 11, 2001. Many security failures contributed to permitting the attacks to occur, including the inability of the legal immigration system to stop the 19 hijackers from receiving temporary nonimmigrant visas to travel to the United States. Fortunately, the system has improved, and vetting failures have become far less frequent after the attacks.

It was 25 years ago today that the Western world completely changed following the attacks on the World Trade Center and Pentagon on September 11th, 2001. The shock of these horrific terrorist attacks caused a seismic shift in security policy both in Washington and Canberra. While the initial shock justified a major response, the focus on non-state and counterterrorist threats soon consumed a generation of national security policy, military resources, intelligence efforts and intellectual attention.

When ADL published its first report on 9/11 conspiracy theories in 2003, it noted that the internet allowed an “unprecedented cross-fertilization of antisemitic ideas” and that they contributed to a “new form of global antisemitism.” The report also noted that these conspiracy theories were likely to endure and “form the basis of a new antisemitic canard that will linger for decades and be used to demonize Jews and Israel.”

Scientists have crossed an important line in biological engineering. In a recent study, researchers used artificial intelligence to design complete sets of genetic instructions for bacteriophages, viruses that infect bacteria. Some of those computer-generated designs produced working viruses when they were built and tested in the laboratory.

Abstract: The most serious near-term threat posed by artificial intelligence to counterterrorism is what information and support AI models are willing to provide to terrorists, and that property is almost entirely unmeasured. This article reports the results of the pilot run of Tech Against Terrorism’s Counter-Terrorism AI Benchmark, which showed that almost one-third of responses from AI models provide meaningful uplift when prompted to assist malicious actors in the preparation of terrorist activity despite guardrails in place meant to prevent such responses.

Artificial intelligence may not create a new kind of terrorism, but it makes existing tactics cheaper, faster and easier. That is the central argument of a July 2026 report from the U.S.-based think tank Center for Strategic and International Studies.

It is a convincing argument, but it leaves one question unanswered: Are different terrorist groups thinking about the technology in the same way?

On July 15, 2026, the Department of Justice took an extraordinary step by filing its first-ever application to activate the Alien Terrorist Removal Court (“ATRC”), a specialized Article III federal court that Congress established thirty years ago as an alternative to administrative removal proceedings for cases i

Congress built the Alien Terrorist Removal Court as a constitutional pressure valve for the rare case in which the government says it must remove a noncitizen on national-security grounds without exposing classified evidence. The Trump administration has now turned that dormant tribunal into a live test of whether a secret-evidence removal system can survive first contact with politics, civil-liberties scrutiny, and the demands of public accountability.
