Too often the United States and its allies find themselves in a counterterrorism policy version of the movie “Groundhog Day,” repeating their past mistakes without end. There are many reasons for these failures, but one is the reluctance of historians to weigh in on contemporary policy debates.

A group of conspiracy theorists used Telegram to call for an armed response to Saxony’s state premier Michael Kretschmer’s restrictions on the unvaccinated. The right-wing extremism branch of Saxony’s anti-terror unit is investigating.

It is, perhaps, easy to look back at the postings of a mass shooter after the event and highlight the red flags that were potentially missed. But how do you know when a young person is writing offensive, threatening or disturbing posts merely to garner attention or to blow off steam, rather than presenting a threat to themselves or others? And at what point in the transition from online threats to real-world harm should concerns by teachers, parents or peers be deemed actionable by law enforcement and other officials?

A German court has found a former Islamic State member guilty of genocide and crimes against humanity for the 2015 killing of a 5-year-old girl, sentencing him to life in prison. The Frankfurt case is the first in the world to decide whether a former member of the Islamic State group played a role in the attempted genocide of the Yazidi religious group.

Cars, SUVs and trucks can be an efficient means of mass killing, and one that can be virtually impossible to prepare against. Furthermore, it is becoming harder to prosecute the driver involved in such fatalities in some states.

“Infectious disease threats will continue to emerge, whether naturally, by accident, or deliberately. Stopping them from spreading and causing mass effects is possible even today, but we have much work to do bringing our assets to bear” said Andy Weber, Senior Fellow at the Council on Strategic Risks (CSR).

The COVID-19 pandemic has led to renewed discussion of biological weapons, but Glenn Cross, a former deputy national intelligence officer for Weapons of Mass Destruction responsible for biological weapons analysis, argues that the development and possession of biological weapons is trending dramatically downward since the end of World War II. “Nations likely no longer see utility in developing or possessing biological weapons for use in large-scale, offensive military operations given the devastating capabilities of today’s advanced conventional weapons,” he writes.

There is a need to construct a versatile system designed to protect the vast array of so-called soft targets such as stadiums, schools, and places of worship. After an eight-month competition among the nation’s biggest universities, DHS awarded Northeastern University a $36 million, ten-year contract to develop such a system.

DHS Counterterrorism Coordinator said that fears the Taliban takeover of Afghanistan could reinvigorate terror groups like al-Qaida and Islamic State, and lead to a surge of attempted infiltrations along the southern U.S. border, have not been realized. “It is just factually inaccurate to frame the southern border as a place where we are seeing a significant number of al-Qaida or ISIS-related terrorists or foreign terrorists,” he said.
