TERRORISMFrom Home to Horror: The Association Between Domestic Violence and Terrorism

Domestic violence is an under-recognized early indicator of terrorism. It is not a reliable solitary indicator, but when observed alongside risk factors, it can prompt authorities to take a closer look at a potential terrorist.

So far as can be demonstrated so far by data, the connection is correlative, not causative: the two behaviors overlap. But knowing this is still valuable. Recognizing the link could enhance public safety and national security.

Research from the UK’s Project Starlight shines a light on this issue. In 2019, an analysis of 3045 individuals referred to the Prevent program—designed to prevent extremism—revealed that more than a third had a link to domestic abuse, either as victims, perpetrators, or witnesses. This figure is far above the general population’s 5.7 percent rate of domestic abuse.

Alarmingly, many of those referred were victims or witnesses of domestic violence, not perpetrators.

Studies in Pakistan have also found that individuals who experienced domestic abuse were more likely to gravitate toward extremist ideologies. The study looked at 562 young people aged 16 to 25 and found a clear link between growing up with domestic violence and later supporting extremist beliefs.

So, we should think of domestic violence as a risk factor in someone’s conversion to violent extremism, just as doctors know that some things point to a risk of disease even though medical research hasn’t yet found out why.

Two examples, among many that could be cited, illustrate the association. Omar Mateen, who carried out the 2016 Pulse nightclub shooting in Orlando, had a history of domestic violence. His violent behavior toward his ex-wife included physical and verbal abuse. Likewise, Khalid Masood, who was responsible for the  2017 Westminster attack in London, had a record of abusive behavior toward his partners.

Though the data does not show a causative relationship, we can reasonably theorize on the drivers. Domestic violence and radicalization both rely on a deep need for control and identity—things extremist groups readily exploit. Survivors of domestic abuse, especially those who experienced trauma in childhood, often find these needs unmet in their lives. By searching for belonging and purpose, they become targets for groups that promise power, community and meaning. Recognizing this is the first step towards intervening.

Central to both domestic violence and terrorism is moral disengagement—the process by which perpetrators view their harmful actions as necessary or justified. Whether it’s in the home or through terrorist acts, violence is rationalized as a legitimate tool to exert power and control.

Australia is starting to recognize this intersection. While there is no formal, integrated action plan specifically targeting both domestic violence and radicalization, there are positive steps being taken that align with the shared drivers of these issues. The National Plan to End Violence Against Women and Children (2022-2032) addresses domestic violence and gender-based violence, with an understanding of the complex social and psychological drivers at play. The plan is a vital first step in reducing violence and promoting the wellbeing of all Australians. Similarly, the Living Safe Together initiative aims to prevent violent extremism and provides support for individuals at risk of radicalization.

While these efforts remain separate, they share strikingly similar goals. Both recognize the underlying trauma and vulnerability that can fuel violent behavior—whether in the form of domestic abuse or extremism. Early intervention, community support and collaborative efforts between social services and national security agencies are core elements of both programs.

Australia should pursue a more coordinated approach—one that treats the prevention of domestic violence and radicalization as complementary goals. Law enforcement, social services and national security agencies should collaborate to identify early warning signs of vulnerability and intervene before individuals are drawn into extremist ideologies.
