I think it's a fair assumption that there would be some changes in the arms dealers and shareholders business practices if their children were being affected (attacked in places where the common people can be found, going off to fight in wars for unclear reasons, etc.). It does give a sense of hope and pride to see more and more people waking up to how wrong it is to have the concept of profit and war so intertwined. The US has done a lot of playing with fire and at least puts on the air of being surprised when it gets burnt. I certainly condemn the radical actions taken against innocent people but (like you) can't say I am shocked that they occurred. There are definitely some lessons to be learned and some foreign policy changes to consider.
