The "United Democratic Nations" would be a pretty small body to begin with. One of the reasons that the UN as now constituated is unable to claim the title of "Parliament of Man" is because of a majority-rule by representatives of non-elected governments. A "democracy" selected from undemocratic peers. There has to be some kind of oxymoron there.
Those leftist democracies would've voted to keep the US out of that UDN because Al Gore 'won'.
