I went to see "Oh Dark Thirty" yesterday and couldn't help but think of how much hatred must have been engendered in all those family members the Seals went to great pains not to kill when they assaulted OBL's compound.
If the children weren't hate-filled on the night of the attack, you can be sure there'll be a small army of family retainers revving them up on a daily basis. I think it would be about the safest bet in town that ten to twenty years from now, our side will be hunting for one and probably more of OLB's many offspring.
Unpalatable as it may be to us today, there was a good reason why, up until medieval times, rivals ensured they killed off all the sons of their enemies as well as the enemy himself. It was a matter of survival, because if they remained alive, those sons would surely come after you to exact revenge. But of course, we don't do anything like that anymore - which might say something of how long our current society will endure, because the people we're fighting sure as hell still do!
