With the collapse of the Assad regime in December, how many of the more than six million Syrians who fled their country during its 13-year civil war will return? It is a question with enormous implications not only for the displaced Syrians themselves but also for the countries that took them in. Wherever displaced Syrians landed, their politicized presence has become a liability for the governments in power and fodder for their oppositions. While Europe would take in around a million Syrians, most Syrians were actually flung across Syria’s borders to Jordan, Lebanon and Turkey; Turkey accepted more than three and a half million Syrians and, since 2014, has been the world’s largest host of refugees.
