Unfortunately most people aren't really motivated to fight for the sake of fighting, they're usually motivated because there's some sort of incentive involved. In a situation where it is just War for the sake of the War, but it's also a War that no one seems to be making any actual progress on, it's not surprising that discontent with the status quo is going to increase without either financial or material incentives to keep going. 

Or because they've been brainwashed, but you already nixed that idea.

I believe that incentive isn't much of an issue. There's plenty of room for whatever cause characters are dedicated to. Its not very different from a setting like Warhammer 40k, for example. The prospect may be grim, but you still need to fight because not only can you try to do what you believe in/want to, but also because even if victory is unlikely, of you give up, defeat is certain.

In other words, you fight not to win, but to avoid losing, pretty much like any other War that had dragged for too long.

I mean characters have individual motivations.  To my knowledge, Juno, Balrog, and Graf are the only ones that fight for the sake of fighting.

Seriously speaking, I don't think that that is Juno's current goal. When I first introduced her, I was very discontent with Eclipse Princess as a character for reasons that don't need to be explained again. This she was an empty character. I changed my mindset now and trying to evolve her through more than one channel, some of those changes should have been perceptible on Hohenheim's event.

In other words, while fighting is Juno's Raison d'Être, it's not the most important thing for her anymore.
