Normally, war refugees find shelter in neighboring countries and return home after the conflict has passed. But this option can be difficult, if not impossible. As long as conflict and persecution persist at home, the refugees will be denied reentry or belong to an oppressed minority. Beleaguered refugees are forced to find new homes elsewhere.
The situation becomes more dramatic when one considers the extent of non-war-related migration.
According to a Gallup survey from 2017, nearly 710 million people want to leave their homeland, mostly from African and Arab states. Their preferred destinations are Western states.
From a humanitarian perspective, this is understandable. Western states offer greater opportunities. But when the number of those willing to emigrate is high, helping immigrants integrate can be problematic, even in stable industrialized countries.
