This article examines the use of coercive engineered migration as a hybrid threat during the 2015 EU refugee crisis. The authors argue that coercive engineered migration can be used as a threat by a state, even when it is not the source of outflows; that it is possible under conditions of an internal or external conflict in the state that is the source of migration; that a state-challenger would most probably be an authoritarian state that supports the government of the emigration state. The authors state that the sound action for Turkey and the EU in the conditions of a crisis that of 2015, would be to develop a migration diplomacy initiative that could contribute not only to a deal but to a sustainable, mutually beneficial solution for both parties.
