As emphasised by Europol, "although only a small contingent of returning fighters might be committed to carrying out attacks in the EU, individuals who have travelled to conflict zones will continue to pose a heightened threat to all EU Member States.
Kot poudarja Europol, „bodo posamezniki, ki se vrnejo s konfliktnih območij, še naprej predstavljali veliko grožnjo za vse države članice EU, čeprav bi utegnil biti le manjši del povratnikov odločen dejansko izvesti napad v EU.
