Dutch fighters in Aleppo warn that preventing Muslims from going to Syria or Iraq increases changes of attacks in the Netherlands, like what have happened in Canada. Experts still believe it’s better to withdraw passports and to prevent further radicalisation.
“You don’t want hundreds of angry potential jihadists in your back yard,” says one of the fighters in Aleppo. They label military and police as legitimate targets for an attack.
Terrorism-researcher De Graaf thinks that if you let these fighters go and they come back, they’ll be more trained and determined. According to Dick Schoof (Dutch National Coordinator Terrorism Prevention) withdrawing passports is a way of preventing them to go into the next phase of radicalisation.
