Here's what I don't get:
It was once said that Uchiha and Senju was on a war for survival, peace, the usual cause of war. Then they say Uchiha started the war because of a philosophy of the tablet. This is where I don't get it. It was thanks to Zetsu that we now know that Uchiha started the war because of misdirection and something that we have to assume that they are full of idiots, which again applies that they have to have the requirements to read the good amount of proportions. Not only that, but why wouldn't Hashirama ask or know the reason for fighting the war when that one does require the explanation and actually something to work over. If it's survival of the fittest, that's self-explanatory, but this one is huge. At least in NnT, they brought up why they were in a fixed war. This one could have prevented, especially since they were in peace in the first place.
This is why the story got so convulated it's best to leave it alone. Before, it was easy to follow, but then the whole philosophy moon eye plan created a huge mess.
The whole backstory with Zetsu makes no sense so I basically disregard it completely as an incompetent author plot device
