This is such a highly disingenuous bad faith argument, Obama won it in 2009, are you suggesting the Nobel committee should have used some time travel technology to peer into the future?
No, the point is that Obama won it in 2009 when he had literally done nothing, except having won an election. The point about what happened after is just to show that the committee was not prescient and full of foresight, that it did turn out that the man who had simply won an election based on promises did not live up to those promises.
