One cannot imagine saying to some foreign State, “Our troops are killing yours, they are invading your land, we are supplying them with recruits and munitions of war, but otherwise we are at peace with you. You must treat us as a neutral, and accord to our citizens, to their commerce and property, all the rights of neutrality.” In short the plan of an international police force involves all the consequences of the proposal of a league to enforce peace, with other complex provisions extremely hard to execute. [Sidenote: Objections.] A suggestion more commonly made is that the members of the league of nations, instead of pledging themselves explicitly to declare war forthwith against any of their number that commits a breach of the peace, should agree to hold at once a conference, and take such measures—diplomatic, economic, or military—as may be necessary to prevent war. The objection to this is that it weakens very seriously the sanction. Conferences are apt to shrink from decisive action. Some of the members are timid, others want delay, and much time is consumed in calling the body together and in discussions after it meets. Meanwhile the war may have broken out, and be beyond control. It is much easier to prevent a fire than to put it out. The country that is planning war is likely to think it has friends in the conference, or neighbors that it can intimidate, who will prevent any positive decision until the fire is burning. Even if the majority decides on immediate action, the minority is not bound thereby. One great Power refuses to take part; a second will not do so without her; the rest hesitate, and nothing is done to prevent the war. [Sidenote: Advantages of pledges.]
