You could at least make the case that Obama promoted -- indeed, in a sense, embodied -- "fraternity between nations," for he was incredibly popular with most of America's allies. (See, e.g., his "rock star" reception in Germany.) Even its enemies were at worst ambivalent towards him personally, and at best they were hopeful that he'd bring about positive change. In this sense, he, at minimum, shored up the self-image of the Western world.
So I thought it was weird, sure, but I could somehow rationalize it.
But this year's prize will apparently do nothing but increase enmity and discord, which strikes me as odd and counter to the prize's intended purpose. The Iranian regime isn't going to look at this prize and see the light; it's going to react indignantly and perhaps violently.
