The extreme liberals do seem to reflect that idea of pulling out now, but that'd be the worst thing to do at this point. US soldiers are directly being attacked to try and sway US civilian opinion, which seems to be the flavor of the month in the insurgent's tactics.
IMO which is based on what I've heard from the guys I served with, and the various sources of news.....
The Iraqi are tired of the insurgents waging their war against the US in Iraq. Things will only change when the Iraqi can secure their boarder, police everything within and the US can pull out.
I do not like to see our military start something and then just quit, so I do support our troops whole heartedly. We may have went to war for questionable reasons, but there is a greater good to accomplish and I know we will complete all of the primary objectives on our plate.
