Ideation, Creation & Everything In Between
It appears that the group ISIS is calling upon people not to flee the country and becoming a refugee but to join the ISIS forces instead. There are most likely many that are doing this in fear that they cannot get away safely to other countries are simply put off by the fact that many countries are saying no, if this was a perfect world we would be accommodating refugees rather than accommodating terrorism by letting these people join.
The ISIS group is claiming and posing that live in Syria is pretty much tip top and is questioning why people would want to leave in the first place this seems like another trick to try and lure people in. This many people would not be fleeing over nothing.
