But why?
I wonder if he is using the White Fang because he lacks the man power or if he plans on framing the White Fang.
I also wonder if the White Fang teamed up with him because their goals align or if they really need him.
You attack the school, you remove the training, remove the training, you have a nice target, especially if you cripple it and take it by suprise, you take out the area's ability to train hunters/huntresses to fight you.
You take out Beacon, you take down Vale.
As for why the White Fang is involved, it's possible Cinder just went "Give me your forces, and we can destroy Vale to create for you a Faunus Nation"
Of course whether the White Fang think that they could backstab her and try this silly "Kill all humans, arrrgggh!" deal they have going is entirely up in the air and most likely expected on Cinder's end.
This is too much chess, I'm going back to drawing.
