“…Research questions that look at foreign fighting are usually a subset of one of two broader questions: what motivates individuals to become foreign fighters (Bakke, 2013; Clifford, 2018; Malet, 2013), or what is it that they do in terms of transnational violence (Braithwaite and Chu, 2018; Cragin, 2017; Cragin and Stipanovich, 2017; Hegghammer, 2013; Hegghammer and Nesser, 2015; Lindekilde et al, 2016; Noonan and Khalil, 2014; Rich and Conduit, 2015; Tammikko, 2018). Separately, there is also legal research on foreign fighter, which looks at how they are treated in different international jurisdictions (de Gutty et al, 2015; Paulussen and Entenmann, 2014).…”
