Retired military captain on a mission to better understand violent insurgencies
Cheng Xu’s work as a University of Toronto PhD student is driven by tragedy that occurred in 2015
* This episode originally aired on October 1, 2021.
Cheng Xu was at the Canadian Forces Base near Wainwright, Alta., when he heard the news that Robert Hall was kidnapped by the Islamist militant group Abu Sayyaf in the southern Philippines.
It was 2015 and the insurgent group aligning itself with ISIS kidnapped Hall and three others, and demanded millions in ransom.
At the time, Hall's son was a soldier under Xu's command.
"I felt extremely helpless. I consider him a good friend," said Xu.
The militants executed Canadian John Ridsdel in April 2016 and then Hall in June 2016, after the Canadian government refused to pay the roughly $8-million ransom per hostage.
'How could this happen?'
"I felt utterly powerless to offer him any kind of support other than to just be there for him," said Xu. "I was in shock. I was confused. I was angry. I had all kinds of emotions that I wasn't capable of processing at the time, because this just felt so incomprehensible. How could this happen?"
Xu left his nearly 10 year military career in 2017 to pursue answers.
He enrolled in a political science PhD program at the University of Toronto, with a focus on insurgencies, counterinsurgencies, and rebel movements.
He made a brief trip to the northern Philippines but wasn't able to get to the southern region of Mindanao, as it was under martial law.
"I thought that perhaps by closing that physical distance... it would allow me to maybe grapple with the reality of it a little bit more rather than just as an abstract concept," said Xu.
While in the north he learned about another rebel group — an alliance between communist guerillas and warriors from Indigenous communities. They were most active in their campaign against the Ferdinand Marcos government in the 1970s and 80s.
"Here I was safe and sound in the [northern] Philippines, sitting next to somebody that I was told was a former insurgent and probably still is armed, having a nice talk over coffee and pastries while at the same time, at the very same moment in the south of the Philippines in Marawi City, Abu Sayyaf is holding the entire city hostage and the government is bombing it to the ground," said Cheng.
The contrast between the south and the north got him thinking about what might be at root of the differences.
Through the course of his PhD he is testing a few theories.
"So the first hypothesis that I had was… rebels who come from hierarchical social environments are much more likely to engage in prolonged conflict than rebels from communitarian or egalitarian social orders," said Xu.
"So then we would expect conflicts involving hierarchical rebels to last for much longer."
And he argues that rebels from hierarchical social environments will be less likely to come to peaceful and lasting resolutions.
"The flip side of that is that rebels that are coming from communitarian or egalitarian social orders, once hostilities have terminated, they are not likely to pick up arms again and resume hostilities," said Xu.
Xu hopes his work will provide further useful context to help de-escalate future violence.

"I truly don't believe that any member of Abu Sayyaf — any of the people who took Robert Hall, John Ridsdel and Sikjen Stad and Marites Flor — I don't believe any of those individuals woke up one day and just decided that that was the action that they were going to take, and that Abu Sayyaf was the group that they were going to join," said Xu.
"I believe they were a product of their social environment. This is not to absolve them or to excuse the action that they have taken and the lives that they have taken. This is just to say that they were brought up in a particular social environment that had opportunities and constraints."
