No, we don't. Which is all the more reason why we should investigate the opposing side.

While it's true that some people start wars just because they can, it is also true that there are wars where if you looked from an outsider's perspective, you could see that both sides have a legitimate purpose. It becomes hard to discern who is right and who is wrong. I don't think that is the case here, but at the very least we could learn more about Nitiri's side and how to act against them.
