Why is ISIL diversifying its victims and recruits?

Earlier this week, ISIL Takfiri terrorists have released a video allegedly showing the beheading of 21 Egyptian Coptic Christians kidnapped in Libya following an earlier announcement of the terror act in an issue of their magazine, Dabiq.

ISIL has so far released several similar videos from Iraq showing the execution of its captives from different countries, including the United States, Britain and Japan.

In its previous video, a Jordanian pilot, captured by ISIL militants when his plane came down in northern Syria during a mission against the terrorist group, was seen while being burned inside a cage.

This is while the ISIL terrorist group continues to accelerate its recruitment efforts across the Europe and US.
