I don't equate neutrality to pacifism. Pacifism only a byproduct of not taking sides in a global conflict. I would also never suggest you not defend your nations. To not do so would negate the benefit of being an alliance at all. My point is only that by protecting green, you are no longer acting as a neutral. You are taking a political position in the larger community that has the potiential of putting you at odds with others in this community by interfering, directly or indirectly, with their conflicts. By all means, do so. You are a sovereign alliance and you can, as such, take whatever stance you please. Just don't claim that stance to be a neutral stance.
It isn't and you're not while maintaining it.
