After an Islamic State group-inspired assault in New Orleans killed 14 individuals on New Yr’s Day 2025, President Joe Biden warned that terrorists would discover “no safe harbor” within the U.S.
Governments usually condemn terrorist teams on this method, in addition to making threats and fascinating in what we name “verbal attacks.”
However such an strategy could also be counterproductive; extremist teams have a tendency to answer such feedback by ratcheting up violence towards civilians. That’s what we discovered after we analyzed six years of information on incidents of terrorist violence and their proximity to authorities denunciations.
Our examine targeted totally on the Islamic State group.
The extremist group got here to the world’s consideration in early 2014, when it started seizing territory in Iraq and Syria. On the peak of its energy in 2015, the Islamic State group managed over 100,000 sq. kilometers (39,000 sq. miles).
Though it has declined considerably since then, the group stays the world’s deadliest terror group – chargeable for almost 2,000 deaths in 2023.
The fast metastasis of the Islamic State group – it has associates throughout the Center East, North Africa and South Asia – mixed with the intense brutality of its techniques, triggered waves of condemnations by international governments. Former U.S. president Barack Obama initially referred to the Islamic State group because the “JV team” in 2014, implying that the group was not as formidable an opponent as extra established teams like al-Qaida. A yr later, he vowed to “destroy” the group.
Our motivating analysis query is whether or not these and related statements have an effect on terrorists’ conduct.
Historically, researchers have dismissed statements like this as “cheap talk.” And authorities officers equally don’t take significantly the chance that such statements may need unintended penalties or inflict precise prices.
However when extremist teams commit terror assaults, they all the time have an viewers in thoughts. And the Islamic State group intently displays how governments reply to its actions.
Terrorist teams use assaults on civilians as an instance the intense measures they’re keen to take to realize their targets. Our analysis means that when governments denounce terrorists, reject their calls for or make retaliatory threats, focused teams infer that they don’t seem to be being taken significantly. Because of this, they commit additional atrocities towards civilians, with the intent of signaling their intentions and capabilities much more forcefully.
To verify this, we used a large-scale machine-coded dataset often called the Built-in Disaster Early Warning System to extract every day information on all occasions involving the Islamic State group for the interval 2014 to 2020. We then employed a coding system often called CAMEO to establish occasions the place governments threatened, denounced or in any other case verbally attacked the group.
We discovered that when governments initiated any type of verbal assault towards the group, the Islamic State group responded by focusing on civilians, usually inside two days of a verbal assault.

Our mannequin confirmed that each three verbal assaults by governments led to a further, in any other case surprising assault by the Islamic State group on civilians. These assaults averaged over six deaths per assault, so the humanitarian penalties of this impact are substantial.
Why it issues
Authorities leaders face huge pressures to handle nationwide safety threats, and terrorism is a robust supply of hysteria for residents.
But, counterterrorism is pricey, dangerous and logistically troublesome.
As such, publicly threatening or denouncing a corporation affords a tempting various technique. However there was little analysis into how authorities leaders’ phrases may backfire, encouraging extremists to assault civilians.
On the similar time, though the Islamic State group has diminished drastically in capability, transnational terrorism continues to flourish. And the resurgence of the Islamic State group stays a menace to safety within the Center East and past.
What nonetheless isn’t recognized
We prolonged the evaluation to the terrorist teams Boko Haram in Nigeria and Al-Qaida in Iraq, and we discovered related outcomes. However additional analysis is required to find out whether or not this sample holds for terrorist teams usually.
Our principle argues that extremists reply so strongly to verbal assaults as a result of they view these remarks as questioning the group’s credibility – a phenomenon we confer with as a “credibility deficit.”
However terrorists have many motivations, together with the need to regulate territory and repress dissent. We don’t but know the magnitude of those influences relative to credibility.
The Analysis Transient is a brief tackle fascinating tutorial work.
