Pundits are already doing everything they can to turn winning into losing and are undermining this achievement. They can't recognize the transformation because they're too busy reporting on death-panels and Iranian nukes to notice the ground beneath their puny feet has shifted. These jerks don't know what a good thing they've got.
Andrew Sullivan has it right:
"I see this prize as an endorsement of his extraordinary reorientation of world politics, and as an encouragement to see it through. In the midst of our domestic battles, and their ill-temper (from which I have not been immune lately), this is an attempt to tell us: look up for a moment, see how far we've come in pivoting away from global conflict, and give this man a break for his efforts and the massive burden he now bears.
And, in the darkness that still threatens, know hope."
