Pacifism and militarism are both necessary in a governing organization. You need collaborative and compromise-ready bureaucrats as much as you need iron-spinned cold-blooded killers. War is, after all, always just a prelude to diplomacy.
What matters more than being pacifist or militant is that you're standing side-by-side in pursuit of some greater goal. The militants must be ready and willing to lay down their arms. The pacifists must be willing to negotiate on behalf of their more aggressive peers. The dispute over when, where, and how to act cannot be put above the goal they are all working towards.
