DHS warned Thursday of a “high risk” from domestic and foreign terrorists for the coming year. The department’s threat assessment points to the prevalence of conspiracy theories, personal grievances and what it describes as “enduring racial, ethnic, religious, and anti-government ideologies,” often shared in online forums, all serving to motivate small groups and individuals within the U.S.

Why do some people resort to violence for their cause? If we take a closer look at the rhetoric of known terrorists, they appear to have one thing in common. They all feel that their group, or a group they support, is unjustly disadvantaged. But not everyone who thinks that their group is unjustly disadvantaged resorts to violence. This begs the question of whether basic personality traits are at play.

Actions taken by the U.K. authorities to prevent terrorism range from preventive action to counter radicalization to arrest and imprisonment for counter-terrorism offences. These activities are supported by counter-terrorism legislation, including the Terrorism Act 2000 and the Counter-Terrorism and Security Act 2015. A new report explores empirical evidence relating to lived experiences of contact with counter-terrorism measures in the U.K.

Misogynist ideology, beyond individual criminal behavior, has fueled violence against women worldwide. A new report explores the phenomenon of ‘incels’ (a portmanteau of ‘involuntary’ and ‘celibate’) and the misogynistic ideology that underpins this global community of men that has become a thriving internet subculture.

Conspiracy theory beliefs and (more generally) misinformation may be groundless, but they can have a range of harmful real-world consequences, including spreading lies, undermining trust in media and government institutions and inciting violent or even extremist behaviors.

Around the world, political violence increased by 27 percent last year, affecting 1.7 billion people. Some armed conflicts occur between states, but there are many more that take place within the borders of a single state. To better understand how violent events spread, a new statistical model identifies links between battles in Africa, but the model can be applied to other armed conflicts.

West Africa’s defense chiefs were wrapping up a meeting in Nigeria’s capital Abuja on Thursday where they discussed the possibility of a military intervention if diplomatic efforts fail to reinstate Niger’s ousted president, Mohamed Bazoum. How likely is West Africa regional bloc ECOWAS to use force to restore Niger’s democracy and what are its chances of success?

Meta’s ‘Twitter killer,’ Threads, launched on July 6 to media fanfare. With another already politically charged U.S. election on the horizon, online hate and harassment at record highs, and a rise in antisemitism and extremist incidents both on- and offline, a new social media product of this scale will present serious challenges.

However dramatic it appeared, the collapse of the Afghan government and military was not surprising. The seeds of defeat were planted long before President Joe Biden ordered the withdrawal. The American project was not based in a clear understanding of the realities of Afghanistan. Well-meaning Americans believed that they could persuade, cajole, or force a project that much of the population did not actively embrace or participate in. A chain of discrete policy errors flowed from this basic failure to adequately understand the country.
