Not for 10 days, but for 2008:
Republicans and conservatives are making hay over the fact that Obama was nominated for a Nobel Peace Prize 10 days after becoming president. And so they mockingly say it's for what he did in those ten days. But the award was clearly given because Obama defeated McCain and put a stop to the neoconservative foreign policy of the previous eight years. A neocon foreign policy that lead to an unnecessary war.
