Great timing,
The UN rule was part of how the game was designed. When coming up with such a huge game I had several issues I had to deal with. In no order of importance I had to find answers to several "problems" (oh, and the game here is credited to someone who helped me run a past game or two, someone who helped me with a few design changes many years ago but he did not design the game and I really wish someone here would correct that error!)
In standard Dip you would have 1 player out of 7 win, or about a 14% chance of winning
adding what 35 powers (the number has varied over time) 1 in 35 is a horrible less than 3% chance of winning!
Dropouts harm any game of course and the larger a game got, the longer it would run making dropouts an even more serious problem here.
I had run the game by hand (no program to adjudicate with) I needed some relief when the game got so big. You guys have it programed here so that is not so much an issue any longer and was probably the least of my worries when designing (especially since running a vote used up the time saved!)
Lastly, I wanted to attempt to replicate the real world and the way it really works. In the real world we have alliances and a somewhat powerless UN.
All these issues were "solved" using the voting procedure. Now the game would be won by 3 of 35 or 8.5% (still lower odds than a standard game!). Alliances would be more like the real world and only having an alliance of 3 would make stabbing allies quite possible and keep powers jockying back and forth playing a political game all while playing a military game. The UN vote helped keep the smaller powers interested in the game, they still had a chance to win (rewarded for being a valuable ally?) and while the military aspect for these powers was reduced, they still had a viable political game to play still. The game also ended in a more sane amount of time while interest was still somewhat high for all.
The UN procedure is absolutely not for all! Some view this game as a pure game of military might. I disagree, the way we need to write to others and negotiate, this only adds to that aspect. But that's my opinion and others who think otherwise are not "wrong" either. I would suggest people at least TRY the vote before making any judgement call but no, it is certainly not for all and some (maybe many) would find it not to their liking! It IS however, "different" almost a variant unto itself and that alone is worth giving a shot?
The game you guys have been playing here is a rather old rev, several years old and has been changed several times since then, each time attempting to fix trouble areas. Is this perfect? probably not, but it most certainly is "better". We have had past discussions about stalemates forming in the late game stages. Again, we have many differences of opinion but the bigger powers get, the more likely a stalemate forms. Look at the standard game and when you wind up with two players nearing say 14 centers each, that game will be chocked full of stalemates itself...part of the game! Something that is difficult to do away with the way the game is designed. Large powers set up defensive walls from one another, making this impossible to do might be impossible in itself but may also be foolish when fixes to this late game stage might very well ruin the early and mid game phases? Yes, others will argue endlessly on this aspect as well, we had such "arguments" in the past and I do not want to get into that again, just understand we have many views and many opinions. The new map at the very least should (we hope) fix at least some of several problems.
Oh, I started with "good timing" I say this because a game that uses such a vote will be starting soon. It's a different game and the vote is also different but it IS a huge whole world game (about twice as large) and has somewhat similar voting as part of that games end game procedure.

I am not running the game and I know the games GM has a few new ideas he wants to try, but those ideas are still unknown even to myself, these are the basic rules however. It's a game of haves and have nots, one with nukes and one where the small will die early in big numbers. but it balances itself out in the end by way of that vote that was discussed here. If you are small and survive, you will be attractive to larger powers looking for partners to end the game with.
