The point re. how muslims are feeling a significant degree of humiliation has validity as well.
Also much of the anger has been directed directly against the jews since ww2.

Every time muslim aggression against the jews has failed and actually made Israel stronger and more resolved to survive.(humiliating)

We are seeing this now with the Iran backed Hezbolah hostilities. Israel is becoming more determined to survive.(more humiliation brewing)
The danger lurks for the possibility of Israel using too much force.

So far it's a battle of news media as well. Who can make the other side look worse.

And the "clash of cultures" issue certainly is valid as well, but I think it will be an ultimate loser for the fundamentalist muslims. The west is simply too strong and too smart to fall into their trap. Their stupidity is only making the west stronger and weakening themselves.

We don't need to annihilate them they will topple themselves in their myopic fanaticism.
