The One can't wait to have his 'Mission Accomplished' moment, can he ? Declaring victory while running from a war, or declaring victory ahead of schedule during a war is foolish, but neither affects the common man as much as an economy thats continuing to collapse. How does one run away from that, or shield the average person so he/she doesn't know they just lost their job ?
Even Lord Rove would have a difficult time making this a reality. And he wields dark magic stolen from the ancients.
