Pulling out in 2008 is madness. It's going to backfire. And if a Democrat becomes president in 2008 (unlikely) I would expect the fallout to ruin their presidency. I'm sorry, but I don't want Obama in office handling that situation. Hell I would actually rather have Hillary deal with that, because she of course would at least have some great people helping her (IE Bill).
No to pullout in 2008. I don't believe in setting a date, I believe in setting specific goals.
