We have already seen that it is the _creation_ of a collective will which we need most in our social and political life, not the enforcing of it; it is the same with a league of nations—we must create an international will. We want neither concession nor compromise. And a vague “brotherhood” is certainly not enough. As we have seen the group as the workshop for the making of the collective will, so we see that we cannot have an international will without creating a community of nations. Group psychology will revolutionize international law. The group gets its authority through the power it has _in itself_ of integrating ideas and interests. No so-called collective will which is not a genuine collective will, that is, which is not evolved by this process, will have real authority; therefore no stable international relations are possible except those founded on the creation of an actual community of nations. What interests us most in all the war literature is any proposed _method_ of union. The importance of an international league as a peace plan is that you can never aim directly at peace, peace is what you get through other things. Much of the peace propaganda urges us to choose peace rather than war. But the decision between “war” or “peace” never lies within our power. These are mere words to gather up in convenient form of expression an enormous amount that is underneath. All sorts of interests compete, all sorts of ideas compete or join: if they can join, we have peace; if they must compete, we have war. But war or peace is merely an outcome of the process; peace or war has come, by other decisions, long before the question of peace or war ever arises. All our hope therefore of future international relations lies, not in the ethical exhortations of the pacifists, nor in plans for an economic war, but in the recognition of the possibility of a community of nations.
