Migrant crisis: Asylum seekers, Economic migrants or terrorist expansions?

Global news is decorated with surprises.  It surprises the surprised minds that some of the asylum seekers have countries of choice. I hope the European countries that have as a matter of dignity and compassion, decided to accommodate the surging asylum seekers , will handle the crisis without causing unsupposed harms. They will be confronted with distinguishing between asylum seekers and migrants including pockets of die hard terrorists that hang the world on her throat.
This calls for an international supports to end war in Syria and other volatile regions in Africa.  All loose if one suffers.
