This Los Angeles Times articlecomes as no surprise.
The Operations Officer for Iraq stated that although a report will be made in September, the military really needs until November to make a good assessment of the surge.
It appears to me that Keith Olberman might have hit the nail on the head. The preparations are being made to blame the public, the Democrats and everyone but GW for failure in Iraq. If the additional time isn’t granted the administration can, and likely will, say, “The Generals said they needed more time and the Democrat congress stabbed them and our heroic soldiers in the back.”
This resembles a Ponzi scheme. After the scheme is exposed and the collapse comes many victims insist that if the scheme’s operator had been given just a little more time everything would have worked out.
