Other than Thanksgiving

It appears the war in Iraq isn't being disguised very well anymore. The body count seems to hover between 100-200 daily now, with the latest revenge being the act of buring alive random people. My question is obvious? What are we doing there?

Not to knock the world's greatest superpower, but in Iraq, we appear to be the world's greatest superpowerless. All of our efforts seem to contribute to nothing more than adding victims to the body count. If we can't even protect ourselves from Iraq "religious" groups, how can we protect them from each other?

We could divide Iraq and tell the minorities in each section to move. Then we could put up walls between them. But, would it eliminate anything? These people desperately want to kill each other, almost as much as they want to kill us. And so far our contribution is probably more in providing the weapons they use against each other than any other single thing.

Should we leave Iraq? What difference would it make other than removing both weapons and targets?
