Introduction – A JiC Symposium on Alette Smeulers’  “Perpetrators of Mass Atrocities Terribly and Terrifyingly Normal?”

Posted on June 18, 2025 by Mark Kersten

What forces make and shape perpetrators of mass atrocities? What makes them tick and ultimately resort to horrific violence? What explains their behaviour, and their decision to resort to the commission of international crimes? What can understanding different motivations and perpetrator types reveal about how mass political violence is waged and instigated? 

In exploring typologies of perpetrators and by troubling dichotomies all-too common to the study of mass political violence, these questions are among those Alette Smeulers seeks to answer in her new book Perpetrators of Mass Atrocities Terribly and Terrifyingly Normal?, published by Routledge in 2024.

Justice in Conflict is honoured and excited to announce that over the next few days, we will host an online symposium on Smeulers’ book, with contributions from authors and experts in the fields of international criminal law and justice, transitional justice, political violence, and history. Contributors to the symposium include Mina Rauschenbach, Iva Vukusic, Carola Lingaas, Bart Nauta, Nandor Knust, and of course, Alette herself.

The following is a description the contents of Smeulers’ book and its aims:

The 9/11 attacks, as well as the ones in Madrid, London, Paris and Brussels; the genocides in Nazi Germany, Rwanda and Cambodia; the torture in dictatorial regimes; the wars in former Yugoslavia, Syria and Iraq and currently in Ukraine; the sexual violence during periods of conflict, all make us wonder: why would anyone do something like that? Who are these people? Drawing on 30 years of research, in this book Alette Smeulers explores the perpetrators of mass atrocities such as war crimes, crimes against humanity, genocide and terrorism. Examining questions of why people kill and torture and how mass atrocities can be explained, Smeulers presents a typology of perpetrators, with different ranks, roles and motives.

Who commits international crimes? A typology of perpetrators

Posted on June 18, 2025 by Mark Kersten

This post is Alette Smeulers‘ introduction to JiC’s symposium on her book, Perpetrators of Mass Atrocities Terribly and Terrifyingly Normal?. Smeulers is a professor at the University of Groningen in the Netherlands. Her research takes an inter- and multidisciplinary approach, focuses on on the causes and perpetrators of international crimes and terrorism, as well as the international criminal justice systems dealing with these crimes. Other contributions to the symposium can be found here.

Adolf Eichmann on trial in Jerusalem in 1961

Discussions of mass atrocities usually involve questions on whether the perpetrators are mentally disturbed sadists or ordinary people, as well as on what drives their actions: ideology, obedience, sadism, material gain, or fear. The typology in my new book, Perpetrators of Mass Atrocities Terribly and Terrifyingly Normal? (which will soon by published in Dutch under the title Angstaanjagend normal) seeks to end that debate. Most (but not all) perpetrators are ordinary people and motives play a role but in different ways for all different types of perpetrators. 

Ideology and obedience are present for all perpetrators but in different ways. For some, ideology (or hatred) is a motivational factor. For others, it is a means to rationalize and justify their crimes after the fact. The same is true for obedience: some perpetrators commit their crimes out of obedience, others take advantage of the fact that atrocities are ordered, accepted or condoned or rely on obedience as an excuse. 

The typology put forward in my book aims to show that people, including perpetrators, are different and are driven by different motives. No one is born a perpetrator; people become perpetrators. Admittingly, this transition is easier for some than it is for others but we all can become perpetrators, although not everyone can become just any type of perpetrator. 

The type of perpetrator we can become depends on situational factors, as well as our genes, upbringing, character traits and the choices we make. Only a few ambitious, power hungry, and ruthless people with leadership skills  will become Criminal Masterminds. Those who are extremely ambitious can become Careerists. Those who have strong ideological rootings can become Fanatics. Those who are driven by their own material or personal gain can become Profiteers. And,  those who are obedient and conformist can become Followers.

“It is time for the further concrete action that has been promised”: an Open Letter to Prime Minister Carney to take decisive action to end genocide in Gaza

Posted on June 9, 2025 by Mark Kersten

The following is an open letter to Canadian PM Mark Carney, written (in both English and French) by 412 Canadian legal, human rights, social justice, international relations, diplomatic, civil society, faith and labour leaders from across the country. The letter was written by former Amnesty International Canada Secretary General Alex Neve, UN Special Rapporteur Leilani Farha, Professor Ardi Imseis, former UN Special Rapporteur and Professor Michael Lynk, Professor Heidi Matthews, and myself,

Open Letter to Prime Minister Carney on Gaza Crisis

We write as a concerned group of 412 Canadians, including academics, lawyers, former and retired ambassadors (including to the United Nations), ministers and public servants, UN human rights experts, and civil society, labour and faith leaders, all deeply concerned with the catastrophic human rights and humanitarian crisis in Gaza, now into its twentieth month.

Israel’s actions in Gaza are broadly understood by international law experts and leading human rights organizations as constituting genocide. We write with the demand and expectation that Canada must do everything in its power to stop these atrocities and support efforts to bring those responsible to account. This is what our signatures on the 1948 Genocide Convention and the 1998 Rome Statute establishing the International Criminal Court demand.

We call for decisive action with respect to five priority recommendations:

  • Work actively towards an immediate, permanent ceasefire and the release of all Israeli and Palestinian captives
  • Insist on full humanitarian access to Gaza and demand that the Israeli ban on the UN Relief and Works Agency be completely lifted
  • Publicly support the role of and fully comply with international courts in holding to account those who violate international law
  • Pursue all possible domestic measures, including immediately withdrawing from the free trade agreement between Canada and Israel, imposing sanctions on Israeli leaders, initiating investigations under the Crimes Against Humanity and War Crimes Act, enforcing a full and comprehensive two-way arms embargo, and stripping charitable status from organizations found to be complici in crimes under international law
  • Without further delay, join the 149 states who recognize the State of Palestine and support all efforts for Palestine to be admitted as a full member of the United Nations

We write with urgency as Prime Minister Carney will host the G7 Summit from June 15-17, which presents a crucial opportunity for concerted action by seven of the world’s most influential and powerful governments that must be seized.

An Accountability Game-Changer? Canada opens structural investigation into atrocities committed in the Israel – Palestine war

Posted on June 4, 2025 by Mark Kersten

Canadian authorities are conducting a structural investigation into war crimes and other atrocities committed in the Israel-Palestine war. First reported by journalist Ben Mussett, the news comes amidst mounting evidence of the intentional starvation of civilians in Gaza, the refusal of Hamas to return hostages, moves to build new (and illegal) settlements in the West Bank, and open calls among Israeli leaders to depopulate Gaza. The investigation marks the first time that Canada has dedicated tangible resources to investigating international crimes in Palestine and Israel.

Here’s what we know so far.

The RCMP opened the investigation in early 2024, just months after the 7 October 2023 attacks by Hamas, and amidst Israel’s ongoing siege on Gaza. 

A structural investigation collects and preserves evidence of war crimes, crimes against humanity, and genocide in a particular context without necessarily linking that evidence to specific perpetrators. Somewhat akin to a fact-finding mission, such investigations can collect evidence by reaching out to victims and survivors who have fled wars of atrocity events to gather their testimony. They can also include collecting open-source evidence such as videos or photographs.

States like Canada can use the evidence collected if an opportunity to do so arises, for example to support a prosecution of a perpetrator who enters onto their jurisdiction. Alternatively, they can share that evidence with other authorities – the prosecutors of allied states or bodies like the International Criminal Court (ICC).

It’s time for states to put their money – and Russian assets – where their mouths are

Posted on April 7, 2025 by Mark Kersten

Given the presence of the Orange Man in the White House, defenders of democracy and the international rule of law can no longer count on the United States for support. Other countries need to step up. One way to do that is to finally act on forfeiting the assets of Russian oligarchs and companies and giving them to Ukraine. It is not Ukraine’s allies, but Russia, who should pay for its illegal war in Ukraine. 

For over two years now, Canada has talked a big game, claiming that it would freeze, seize, and forfeit the assets of private Russian entities and oligarchs and then turn them over to help Ukraine’s recovery. At first, there was some significant movement. In 2022, Canada restrained $26 million dollars held by a company, Granite Capital Holdings, owned by Vladimir Putin’s pal, Roman Abramovich. In 2023, it seized an enormous Antonov airplane from the Volga-Dnepr company. No state had ever tried to forfeit the assets of sanctioned persons before. But Canada had amended its Special Economic Measures Act and was poised to be a trailblazer.

The next step was to get judicial approval of the forfeiture of the assets and then send them to Ukraine. Yet the government has not even filed in court. Global Affairs Canada has refused to shed light on what’s happening and claimsthere is no timeline for action. In Ukraine, death and destruction continues.

Separately, announcements by Prime Minister Justin Trudeau on a recent trip to Kyiv have caused confusion: is Canada now going to seize Russian state assets to help Ukraine? So far, the answer is no.

The Past Roams in the Present: Transitional Justice, Fascist Cultural Property, and Mussolini’s Chicago Footprint 

Posted on March 25, 2025 by Mark Kersten

Mark A. Drumbl is Class of 1975 Alumni Professor of Law at Washington and Lee University, where he also directs the Transnational Law Institute. Many thanks to Ana Laura Coria for research assistance, and Inge Gruenwald, Barbora Holá, Mark Kersten, and Alex Klein for comments. All photographs – except for one, as indicated — are taken by the author.

The flight plan of Italo Balbo and the Italian Air Armada, from the Official Book of the Flight of Gen. Italo Balbo and His Italian Air Armada to a Century of Progress (1933); see https://www.publicbooks.org/balbo-monument-chicago-soldier-field/

Italian dictator Benito Mussolini gifted a fascist monument to the city of Chicago in 1934. It still stands, today, in public. I went to see it in early March 2025. I did so when I was in Chicago for the International Studies Association Annual Meeting. 

The monument was easy to find. It’s a twenty-minute stroll from the downtown Chicago Hilton Hotel, where the conference was held.

The story of this monument traces to 1933. In that year, twenty-four seaplanes left Mussolini’s Italy and flew, via several transatlantic stops, to the United States, notably, to the shores of Lake Michigan. These planes were commanded by Italian aviator Marshal Italo Balbo. Balbo was a member of the Blackshirts (fascist paramilitary). He was appointed Air Minister in 1929 and built the Aeronautica (the Italian Air Force). An avowed fascist, Balbo was central to Mussolini’s ascent to power. Mussolini also envied Balbo and saw him as a rival.  So, Mussolini conveniently sent him to Libya, where in 1934 he was named Governor-General of the then colony. Balbo was a key part of Mussolini’s colonial wars in Ethiopia, Libya, and Somalia. Balbo extensively bombed Ethiopia. Although Balbo opposed Mussolini’s alliance with the Nazis, Hitler celebrated his tactics. Balbo died in 1940 at the age of 44. He was reportedly downed by friendly fire over Libya. His remains, initially interred outside of the Libyan capital of Tripoli, were returned to Italy in 1970 after Libya’s then leader, Muammar Gaddafi, threatened to destroy all Italian cemeteries in the country.

In 1934, Chicago held the World’s Fair (entitled the Century of Progress Fair). These World’s Fairs – precursors to the EXPOs – were a really big deal. In it, countries gathered to share their technological, artistic, and scientific innovations. The World’s Fairs were prowess flexes. Many people attended.

All of these threads weave together. The monument takes the form of a Corinthian column dedicated to the honor of Italo Balbo and his aviation accomplishments. Mussolini offered it to Chicago for the Century of Progress Fair. It arrived by boat. It is unsurprisingly called the Italo Balbo Monument. The Balbo Monument was warmly welcomed by Chicago officials, including the mayor, and dedicated on Chicago’s Italian Day in 1934. Erected for the Fair, and placed in front of the plane-shaped Italian Pavilion, the monument remained after the Fair shut down and the Pavilion packed up. The Balbo Monument, ironically, is the only fixed remnant of the 1934 Fair.

Rodrigo Duterte’s “Drug War” Lands Him in The Hague: Some Initial Thoughts

Posted on March 12, 2025 by Mark Kersten

The brazen and brash former President of the Philippines, Rodrigo Duterte, has been surrendered to the International Criminal Court (ICC), where he faces charges of crimes against humanity, allegedly committed during his so-called “drug war”. A warrant for Duterte was issued under seal earlier this week and communicated to authorities in the Philippines, who subsequently arrested Duterte upon his return from a trip to Hong Kong.

According to the warrant against Duterte, he is charged with murder as a crime against humanity. The ICC judges who authorized the warrant stated that “there are reasonable grounds to believe” that the attack against civilians in the Philippines  was a matter of policy under Duterte and “was both widespread and systematic: the attack took place over a period of several years, and thousands [of] people appear to have been killed”.

So, what does Duterte’s surrender mean and what happens next? Here are a few thoughts on this momentous development.

First and foremost, the arrest of Duterte is a vindication of what victims and survivors of Duterte’s “drug war” have insisted for many years: the former President is responsible for atrocity crimes and should face his day in court on charges of crimes against humanity. Duterte’s arrest is likewise a victory for the tireless and courageous human rights advocates and journalists who never stopped fighting to hold Duterte to account, despite the great risk to their personal safety and well-being. As the ICC’s Office of the Prosecutor has stated, it was the victims, survivors, witnesses and activists whose “strength, courage, and perseverance make these significant developments possible.”

Second, Duterte’s arrest is a timely win for an embattled ICC. It is no secret that the Court is facing a multi-pronged attack from the United States, Israel, and Russia, among others. Even its so-called friends have undermined the institution. In recent weeks, Italy – a member-state of the ICC – refused to cooperate with the Court and surrender an ICC suspect, wanted for atrocities committed against migrants in Libya, to The Hague.

New Book Alert! Hybrid Justice: Innovation and Impact in the Prosecution of Atrocity Crimes 

Posted on February 27, 2025 by Mark Kersten

Dear readers,

I am very happy and excited to announce the publication of a new book, co-edited by Kirsten Ainley and myself, entitled Hybrid Justice: Innovation and Impact in the Prosecution of Atrocity Crimes.

The volume is the product of the Hybrid Justice Project. Here is a synopsis of the book:

The last decade has seen the unexpected re-emergence of hybrid and internationalized courts, tribunals which operate with varying combinations of national and international law, procedure, and staff. The permanent International Criminal Court (ICC) should have made such hybrid mechanisms largely obsolete, yet hybrids have recently been established or proposed for crimes committed in Chad, South Sudan, Israel/Palestine, the Central African Republic, Kosovo, Syria, Sri Lanka, Myanmar, The Gambia, and Liberia, among others. One of the most pressing conversations in international criminal law is whether and how a hybrid tribunal can be set up to address Russia’s commission of the crime of aggression in Ukraine. Hybrid courts are often a response to the need to make justice more—albeit not entirely—local. They operate with differing degrees and elements of national and international law and staff. Some hold proceedings in the relevant situation country, others in third-party states, and yet others offer a mix of both. All contribute significantly to the broader ‘system’ of international criminal justice. This edited volume examines the resurgence of hybrids. The contributors—lawyers, academics, and activists—offer analyses of the ways in which hybrids have succeeded or failed to achieve their objectives and, in doing so, help to clarify what makes hybrids more or less likely to succeed in their mandates and impacts. The authors focus on hybrid courts and resilience: the resilience of hybrid mechanisms to withstand political and other pressures in order to deliver justice and accountability, and the potential contribution of hybrids to the resilience of affected communities. Chapters are grouped into sections on the fields, practices, innovations, and impacts of hybrid courts, to draw out lessons for the future of hybrid justice.

It’s all about control: U.S. sanctions against the International Criminal Court and navigating a path forward

Posted on February 12, 2025 by Mark Kersten
(Photo: AP)

The Trump administration’s Executive Order issuing sanctions against staff of the International Criminal Court (ICC) have been called many things: vindictive, disgraceful, as well as an act “that puts the United States on the side of war criminals at the expense of victims of grave crimes seeking justice.” As severe as they may be, these descriptions are nonetheless accurate. But who is targeted by theses sanctions, why were they issued, what impact might they have, and where do they leave the ICC? In what follows, I endeavour to answer these questions.

American sanctions against the ICC did not come as a surprise. It has been understood for months now that the Trump administration is infected by rapidly anti-ICC sentiments. Since the 2024 presidential election, it was accepted by the Court and states alike that the U.S. would resume its efforts to cripple the Court, initiated at the end of Trump’s first presidency. It is easy to forget the attacks on the ICC by the likes of National Security Advisor John Bolton – who called the Court “dead”, and Trump’s former Secretary of State Mike Pompeo – who called it a “Kangaroo court”. The most recent sanctions are a continuance on a theme, not an aberration.

In January, Republicans tried to pass a bill authorizing sanctions through Congress, but were blocked by Democrats in the U.S. Senate. As a result, the latest sanctions come via Executive Order. The greatest fear in recent weeks among proponents of the ICC was that the U.S. would issue sanctions not just against ICC staff, but against the Court itself. That would pose a potentially existential threat to the institution and its ability to function. Reflecting those fears, it was reported that staff at the Court were backing up data and evidence in case they would not be able to access the Microsoft platforms that the institution had become dependent on in recent years. 

For now, however, the White House has decided not to sanction the Court as a whole but rather focus on a list of individuals to be targeted. As this moment, only one person, ICC Prosecutor Karim Khan, has been listed. If the U.S. continues to target only individual ICC officials, the sanctions will neither paralyze nor destroy the Court. They may interfere with certain actions and will certainly be figured into decision-making. For example, will Khan be permitted to speak at the United Nations Security Council, which he does twice a year, or to attend the Assembly of States Parties of the ICC conference when it takes place at the UN in New York? Regardless of the answers to these questions, sanctions targeting individuals are manageable, especially if the European Union invokes its Blocking Statute to insulate sanctioned ICC staff and ensuring they can access financial and banking institutions.

Here’s what needs to happen in the wake of Trump’s sanctions against the International Criminal Court

Posted on February 6, 2025 by Mark Kersten
The International Criminal Court (Photo: ICC)

It wasn’t a surprise, but nevertheless, the Executive Order imposing sanctions on the International Criminal Court (ICC) are a deeply troubling development. As Amnesty International’s Agnes Callemard put it, the order “is vindictive. It is aggressive. It is a brutal step that seeks to undermine and destroy what the international community has painstakingly constructed over decades… The sanctions constitute another betrayal of our common humanity.”

It is difficult to know what to do when so much of what we care about and advocate for is under attack. What are we supposed to do? How do we protect the institutions that accountability advocates worked so hard to create – often against the odds? The threats posed by the Trump administration – whether punitive tariffs, arbitrary pauses on foreign aid, or attacks on the ICC – can leave us with a feeling of impending and paralyzing doom. But there are things that can be done to protect and promote institutions like the ICC. While far from perfect and undoubtedly in need of some reform, the Court is worthy of protection from efforts to kneecap and destroy it. In that spirit, here are some things that states and proponents of the institution can do as it faces a potentially existential threat from the U.S.

Hold firm. American decision-making often has the effect of taking all of the oxygen out of the room. President Trump, in particular, has a penchant for ‘flooding the field’: saying and doing multiple atrocious, racist, or hurtful things, in order to fragment media and diplomatic attention. But the ICC must not be deterred by the Trump administration’s bullying. While it may be easier said than done, the Court should not be deterred from continuing its work in the face of Washington’s threats. Its warrants for Israeli leaders are based on firm and compelling evidence. Its investigations into Palestine and Afghanistan are on solid ground. Backing down and showing weakness – especially against Trump – would only leave the Court more exposed to intimidation and vulnerable to interference.

The Court’s staff should likewise remember that when American frustration towards the ICC is at its greatest, that antipathy signals to the rest of the world – which, it should go without saying, matters as much as the United States – that the Court is challenging a political status quo where might is right and Washington can stomp on the rules-based international order when it so pleases. The fact that Trump and his sycophants are so hysterically and unreasonably upset with the ICC is a symptom of the Court’s success, not its failure.

Rally around the Court and its mission. The ICC is far from perfect. It is entirely legitimate and natural to criticize its decisions. But member-states and advocates need to remind themselves and others that the Court is a global achievement worth promoting and protecting, warts and all. It remains the only permanent international court capable of investigating and prosecuting international crimes. It has a role to play in contexts of political violence and it continues to have purchase for states whose civilians have faced atrocity crimes, as demonstrated by the recent decisions of Ukraine and Armenia to join the ICC.
