Hmm... I think this war is pretty much justified, and I think we should keep fighting it until we win completely (we're winning, just haven't won yet). I would really hate for this to become another Vietnam or Samalyia, if we left we would just be confirming the idea that if you kill a few of us we'll leave. And let's face it, Iran is going to develop nuclear weapons within the next few years and we need to stay there to put a stop that BS.
Also, I don't know why people can be so narrow minded and idiotic as to say we never found any weapons of mass destruction in Iraq. Becuase the fact is, there are weapons of mass destruction there, and we're fighting them right now; people. When 9/11 happend, there weren't any missles or bombs, there were a bunch of doon coons with box cuters. People can be made into weapons of mass destruction, we've seen that. So until we rid Iraq (and whoever else has the stupid idea of trying to f**k with us) of these "weapons" no one will ever really be safe.
