To be fair, Putin has "invaded" Crimea without killing anyone... something neither the Maidan or the ousted government can say they've done.
That is an impressive feat, and if Crimea votes for independence or greater autonomy in the upcoming referendum then I would say he deserves it for averting a potential crisis.
I really doubt that most of those protesters in Maidan were actually ukrainians. I think, heard and read about a lot of evidence that those causing violence were mostly russian agitators. Adding in the possible russian snipers causing chaos, I'd say that he would be the least suiting politician candidate for such award.
