This is an opinion made by a Japanese columnist why the young join ISIL. Main reason why the young join ISIL is not the ISIL’s ideology but their anxiety of not having a comfortable place in their society or family. Generally, the young are sensitive and naive . In this unstable time, the young is eager to violate already-made authority or rule that is covered in our society and the extreme ideology like ISIL accelerate the young dangerous desire. What do you think about it?
