THE thing that seems odd is, if you take out religion and madness ( which you can't ), what cause do these blokes terrorise for?
And isn't that the thing? We just don't know.
I used to think I knew, then I remember reading something about life in Palestine, and realised that, if I were in a situation like that (which could just as easily apply to Syria, or Iraq, or...), I might well be just so fucking angry that I wanted to hit things and hurt people.
And even that probably doesn't come near even a slight understanding of what is going on.
One thing that does seem to emerge is that the kind of people who get caught up in this stuff - the footsoldiers, if you will - aren't really particularly religiously motivated, or especially idealistic (though they may claim those as after-the-fact justifications for what they are doing), but lost. For whatever reason, they have lost, or never had, a "place" in society. Along comes something like ISIS, al Quaeda, or an intifada, and all of a sudden, there's a cause they can join, something to give their life meaning, even if it means a very much shorter life.
I suspect, more than any other reason, that's why people like this - overwhelmingly young, disenfranchised men - end up committing atrocities, as the pawns of far more cynical and manipulative agencies.
Come to that, it's not a great deal different from the way economic conscription often works for Western militaries, too.
