Russia doesnt need to infiltrate isis, they just need to let it happen which they did.
Examplary reaction Ive seen a few times:
My prediction: mobilisation focusing heavily on religious minority, their passport 'volunteers' have been exhausted, now the rest will be called in.
Who's going on the street to protest if its just muslims? Let them atone for their religious brothers with blood of their own, you will hear.
Just like they dont give a **** about the convicts who turned into maggot food, no muskovite will cry over the landfill of bodies they'll be dumped in, I guarantee you that.
