That is not true Sable ... after us rebels crumble NR we are all planning to build a bonfire and having a kumbaya moment.Would still rather be on NR (thinking the most unbiased I can). NR knows it's enemies and is holding the world at a stalemate and is in the absolute best position to win.
If tomorrow NR were to crumble, the rebels would have to fight each other for power and essentially immediately split (we're already seeing signs of this with NR still around).
On the other hand if just 1 or 2 rebel alliances crumbled NR would be back on top and essentially set up for a win.
In a tie-breaker like this you pick the side with a better position and that's clearly the 1 alliance side, who has been working together since almost the start, rather than the many/spread out alliance side, where you can see cracks.
