@sassygirl15: Thank you for being specific. Checking, I don't see any connection between the wedding bombing in Turkey and Syrian refugees, though maybe I've missed it. As for the other attacks there is definitely cause for concern, but there is also the possibility that ISIS may be hoping to make the West paranoid about Syrian refugees, through planting stolen or fake passports at the site of bombings. In which case Trump is playing right into their hands. This article is worth reading:
