He was wrong though. The problem is that everyone that was right died except for Saw. Perhaps if they had worked together more closely their resources would have more effectively been used and losses wouldn't have doomed the revolution.
I'm convinced that if Nemik had been on Yavin with the new army that was being built he would've had theory as part of their training curriculum and you would have had a military with a real ideology that couldn't be coopted by liberal politicians that took over leadership. If relations weren't so strained more bodies could've taken part in the robbery and Nemik might not have died, I'm certain that Saw had more experienced fighters that would've handled crowd control and their personal nerves much better. Luthen's team were very green, scared and jumpy.
