I can't wait for the self-proclaimed experts of this forum explaining how France has failed to integrate the arabs and that their children are terrorists in the waiting while:
1) this guy isn't an arab
2) he never was born in France
Since he was actually Chechen, are Chechen immigrants a sizable group in France?no there's only 35.000 of them in France
And if so, are they considered a "problematic" group?
Yes, when we talk about the Russian mafia, a major part of it is Chechen in nature.
On a more broader global perspective, Chechens were the backbone of ISIS in Syria and a reason for why ISIS was weaken after the Battle of Kobani was because many of these Chechen veterans died.
In general the average Sunni Arab Islamists are in general unable to hit a nail with a hammer without putting the nail through their own eye. Which is why they have a so incredible high failure rate, the Chechen on the other hand are competent, willing to get their hands dirty, willing to do plan and do the hard work and true believers. That is a incredible dangerous combination when it's mixed with such as toxic religion like Islam and depraved ideology like Islamism.
