It is becoming clearer that attacking ISIS in Syria makes as much sense as attacking Iraq did after 9/11. The source of the problem was in the US, not in Iraq. Just as the source of the problem in Europe is in Europe. 

We can see it more clearly from our side of the ocean. Doesn't make it any easier to deal with. 

And our problem in the US was and is in the US. The problem here is that oil and war make too much money for big corporations, and we're too comfortable in our spoiled lifestyles. 

Maybe software can eat that problem too, but I kind of doubt it.
