Reading the latest chapter I realized something. If Itachi was still in the plot as an edo he could have just used Izanami on Obito. Easy way to win the war right there.
In the recent chapters it turns out that a lot of the clans banded together to form the village with the Senju and the Uchihas. What the hell happened to the Senjus then? Before the recent chapters everybody thought the other clans were the Senjus, but it's apparently not.
