woofgang, it doesn't matter in a sense whether the letter is a fake or not.
Ukrainian government wantint to nominate its president for the Nobel Peace Prize would hardly be the most unlikely scenario. All sorts of nominations are made for this prize every year. Vlad Putin was nominated by the Russian duma a few years ago.
The subtext to all of this is that there is a whole blogosphere of conspiracy theorists, some naive, some cynical , whose mission or proclivity is to equate anything to do with the Ukrainian government as being akin to baby boiling or the worst sort of neo-fascism.
It is laughable but they exploit the fact that most people don't know any better (and most normal people understandably couldn't care less)
