Were you around then? I'd rather trust the people who experienced both NPO-FAN wars themselves instead of looking at naturally biased source material. Whether the CB was just or not, I don't think you can use what basically amounts to a propaganda reel to make your point. Then again history is written by the victor, but that has yet to be decided.
Either way, I think NPO has made a martyr out of FAN. Your tired excuse of using them to "train" your lower nations no longer holds any weight since they have what, 3 nations in anarchy right now? Attacking ghosts provides a better military exercise than stubbornly trying to regain face by attacking an invisible enemy.
