Western culture ? why is that anybody who is not a rabid, backward Islamist is called "western" ? These people are backward and uneducated. The world is full of weird and wonderful religions but the vast majority of them don't behead innocent aid workers, sent to help their people.
The real question is ....what is to be done ? We clearly cannot just stand by by while another 100,000 innocent people are murdered. I'm not sure of the answer but doing nothing but stand on the sidelines, tutting, is not going to work any longer. It seems impossible to debate or negotiate with them. Even talking to these people is like trying to nail custard to the wall.
Sooner or later, the free world, a phrase that i prefer other than the "western world" is going to have to act. Compare the situation in the Middle East with the former Yugoslavia...what would it be like in the Balkans now, if we hadn't acted in the 20 years ago ? How many more people would Milosevic and the others barbarians have tortured and killed if we had just stood by ?
