The youngest was 9 when he came to the US, all his formative views were determined by then in his former homes. He knows violence, maybe he adapted to US life for a time but I think we’ll find that the older brother re-ignited those embers and radicalized this kid after he himself spent time being trained in Russia. While they’re not equally radical, just look at the mom, dad, uncle, and aunt - they’re all a little off-center, doubtless as a result of the earlier lives they lived.
If anyone did it, I'd look at them first..
I’m seeing this the same as you in regard to this kid being “trained” since his earliest years to wage a war of this sort. So many here in America just really have no clue what these people have gone through, and what they’ve experienced, and what they’ve been taught by their experiences. These are not “kids” in the sense of the term we would use here in the US... It’s like the kids growing up in Gaza - there are certain things they are taught that makes them likely to commit these acts. Same with these “kids” from Chechnya. It’s a totally different world for them, and people just don’t get it.
[Sorry for the semi-rant - have heard so many people on other websites bemoaning the fact that these kids are so young, and they can’t be islamic terrorists! As if because the kid was at Dartmouth means he can’t be a psychopath? It’s even worse than that really because these people are technically “sane” and intelligent, they are just completely twisted.]
