do you doubt they throw gays off roofs.. rape little girls and kill them? and light people on fire?
I don't!
And while for all practical purposes I suspect that this latest "news" (the thing about them feeding some kid to his mother) is fabricated I'll concede that it certainly isn't out of character for Daesh and might very well be true.
That said, so what?
While brutal, it isn't terrorism.
Nothing Daesh has done really rises to the level of terrorism (and certainly not the kind of terrorism we should be worried about).
They're more focused on establishing the Caliphate than on exporting terrorism to the West.
Though they may be an offshoot of an offshoot of al Qa'ida they're not... (drum roll please)... al Qa'ida (and weren't really even al Qa'ida to begin with, though they did hitch their wagon to that organization temporarily when/while it was expedient to do so).
Probably the worst thing we could do is anything that would drive Daesh and al Q back together and having both the near and far jihads organized/financed/run out of the same shop - and I think acting like they're essentially the same thing (The Terrorism!!!) certainly works more to their advantage in this respect than to ours.
As long as al-Baghdadi, and al-Zawahri are fighting each other for money/thugs/street cred they're doing part of the job for us.
I say **** the Arab/Muslim people that Daesh is currently preying on as they seek to establish their brand of Islamic hegemony on the little corner of the world they presently control (and to think that they're actually going to grow far beyond what they currently control is foolhardy at best).
Let them build their little empire and then let them consolidate Islamic extremism within it, and then once they mature into their next phase of development and start looking outward then we hammer their capitol with JDAMs and TLAMs and cut the head off the snake.
But to waste time/money/lives now in a further attempt to play wack-a-mole with people living in caves and mudbrick huts is just stupid.
If the Iraq and Syrian people have to play canary in the coal mine for the time being why should we care?
