That's why I'm saying by both sides bombing the crap out of each other be it via F-18 or underground bomb is only going to continue the cycle of violence. The crux of the matter is that of you look at what's going on more closey you will see that there is really a fundemental war of ideas going on between, and lets be open about this, the West and Islam. To be really clear, lets use the term capitalism and Islam, since the word West is very general and refers to all people in the West regardless of their personal view.
If this war between ideas is not resolved, then the bloodshed will continue. And this isn't something as basic as you don't belive in my God, its more ideological. It's a war where two fundemetally different ways of life are meeting and they are meeting head on. They cannot tolerate the existance of the other, just like in the Cold War, due to their expansionist nature. There are people on both sides with their aims and objectives, and some of them will use physical means to achieve their objectives. In my view violence is counter productive, and should not be used.
At the end of the day if we avoid examining these ideas and be ready and willing to approach them with an open mind then whether or not we as individuals pick up a gun and fire will not change the fact that our actions will cause ignorance in the world to prevail and thus result in more unnecesary killing.
Before anyone points out that I havn't actually pointed out the differences between Islam and Capitalism, or infact why both capitalism and Islam can be spoken of on equal terms, then PM me. People have written books upon books on issues like these and I'm not going to start writing a book in this thread.
