I really appreciate the fact you think about this and don't just flame out.
I study Classical Civilization in graduate school. I mention this to let you know that I am a student of human history and I take your points regarding the savagery of the human race. I agree. We are a violent species. At the same time, we certainly are capable of being humane, decent, noble amd merciful. Witness what happened in New Orleans. Some folks went the way of the savage; others (more I think) reached out to help their fellow humans and to cooperate in order to survive. So I guess it can really go either way with us humans and it seems as random as sunspot activity.
I have no interest in (and I am deeply horrified at the thought of) being a part of ANY sort of fundamentalist state, Jewish, Christian or Moslem. I see religious fundamentalism as one of the greatest threats to human liberty and justice in the 21st century. That includes here in the US. At the risk of offending lots'o people, I think religion is part of mankind's primitive past and the sooner we grow out of that foolishness, the better off we'll all be. That does not mean I don't believe there is a God or that there is anything wrong with seeking a connection with a higher power. The problem is when one cannot tolerate the idea or existence of another way of believing/relating with that higher power. If religious folk could really, truly tolerate difference and diversity, alot of problems would suddenly go away.
You are right, this is a sad, violent world full of sad, violent people. Misery loves company so they want other people to be sad and violent like them. That or dead. I remember T. Roosevelt's advice, walk softly, carry big stick. Well, we've forgotten to walk softly and we've been applying the big stick early and often. Strangely, that seems to piss people off. We didn't cause terrorism any more than we caused the rise of fundamental Islam. However, our heavy-handed meddling in others peoples affairs has gotten us stuck to a nasty little tar-baby and it has made us the target of their wrath. I do think that there are people in this world, Moslem and otherwise who hate us so much it would bring them great joy to see our nation wiped out but only after we had suffered much.
A solution? There is no quick and easy way to solve the problem, in the main because our leaders and their leaders lack wisdom, insight and humility. We would have to learn to live with and tolerate uncertainty and fear. We would have to learn how to walk softly again. What I mean by this is whole hell of a lot less overt conventional response with an increase in the numbers of Special Forces personnel. Why? Because they are THE experts on dealing with insurgencies. Dealing with terrorism is incredibly complex and I think it requires a hell of a lot more subtlety than we are currently using. Economic help would not hurt. A real effort to give Palestinians a homeland will help. They don't hate our freedom, they hate our arrogance and ignorance. Palestinians hate us for helping Jews take away their country, driving them into refugee camps and then saying tough tit. The use of conventional military force should be extremely limited. Skilled diplomacy combined with a bit of quiet arm-twisting would be useful. Not abusing prisoners, not taking photos of the abuse and not being a backward-ass country retard (like Lynndie England) would go a long way towards helping improve our image and relations with Moslems. We could show a little respect for their culture.
This is getting long so I'm going to stop here.
