The thing is, part of their whole indoctrination will have been the making a similar assumption about British soldiers being trained to do the same thing.
Of course, that's not the case, but I can't see how laughing at the deaths of these people is going to do anything to stop another 20 lining up to take their place.
I mean it's the centenary of WW1 this year, and you suspect little sadness will be felt that so many millions died because people were incapable of co-existing together peacefully. I can't help but feel that until we learn to do that then we'll stagger from one war to the next.
