Incidents of antisemitism targeting Jewish institutions remain at historic levels in the United States, jumping 61 percent from 2020 to 2021. There has also been an uptick in threats to Jewish community and religious spaces, including synagogues, JCCs and Jewish day schools.

Police have arrested 25 people of the Reichsbürger movement, accusing them of planning to overthrow the German government in a series of raids across the country. Reichsbürger adherents have been stopped from attempting violent action before, but this latest incident and its alleged members have caused greater concern.

Many counterterrorism experts and observers have long said that one of the key failings of the post-9/11 era was a lack of a cohesive, overarching strategic concept. Research indicates that short-term operational and tactical planning can dominate policy and security risk management at the expense of future scenario planning.

A report by the Special Inspector General for Afghanistan Reconstruction (SIGAR), which examined the U.S. investment in the conflict-torn nation, blames Afghanistan’s internationally supported, now-defunct government for failing to recognize that the United States intended to withdraw from the country, one of several factors contributing to its rapid collapse in August 2021 before the Taliban seized power.

As a study my team and I conducted highlights, frightening proportions of the public believe in conspiracy theories that doubt the truth of reported events, even terrorist attacks. In our findings, one in seven respondents believed victims of the May 2017 Manchester Arena bombing were not really victims at all, but “crisis actors” – essentially, that they were brought in to pretend to be victims of an attack to manipulate public opinion. We also found that one in 20 were convinced the attack in Manchester and the 7/7 bombings in London in 2005 were “hoaxes”.

Anyone who has ever gone to a major sporting event or concert, taken public transportation, even visited a farmer’s market on a brisk weekend morning, has likely benefitted from soft-target physical security—and perhaps didn’t even know it. DHS S&T is working developing a suite of decision-support software known as Special Event Planning Tools (SEPT) to help those in charge of securing soft targets.

In the U.K. and overseas, there has been a shift towards self-initiated terrorists operating independently from organized groups with increasingly personal ideologies and warped views used to justify violence. The U.K. is updating its counterterrorism system is so it can continually adapt to new and emerging threats.

Recent large-scale projects in the field of Artificial Intelligence have dramatically improved the quality of language models, unfolding a wide range of practical applications. Language models are statistical models that calculate probability distributions over sequences of words. Language models can make many beneficial contributions, but they may also be misused by extremist actors for propaganda purposes.

The analysis of terrorism is plagued with definitional disagreements, and most of the definition in use suffer from gaps, ambiguities, and inconsistencies. Daniel Byman writes that terms such as “groups” or organizations” no longer applies to many who engage in terrorist activities – but the term “lone wolf” is also misleading. He offers the term “network: “Network analysis can be another way to identify the contours of a dangerous movement.” Because so many of today’s terrorism challenges “are better characterized as movements or networks rather than as groups or organizations, it is valuable to explore how such amorphous concepts might be operationalized.”
