What is true of this country is true of others. To agree to abide by the result of an arbitration, on every non-justiciable question of every nature whatsoever, on pain of compulsion in any form by the whole world, would involve a greater cession of sovereignty than nations would now be willing to concede. This appears, indeed, perfectly clear from the discussions at The Hague Conference of 1907. But to exclude differences that do not turn on questions of international law from the cases in which a State must present the matter to a tribunal or council of conciliation before beginning hostilities, would leave very little check upon the outbreak of war. Almost every conflict between European nations for more than half a century has been based upon some dissension which could not be decided by strict rules of law, and in which a violation of international law or of treaty rights has usually not even been used as an excuse. This was true of the war between France and Austria in 1859, and, in substance, of the war between Prussia and Austria in 1866. It was true of the Franco-Prussian War in 1870, of the Russo-Turkish War in 1876, of the Balkan War against Turkey in 1912, and of the present war. [Sidenote: But would reduce probability of hostilities.] No one will claim that a league to enforce peace, such as is proposed, would wholly prevent war, but it would greatly reduce the probability of hostilities. It would take away the advantage of surprise, of catching the enemy unprepared for a sudden attack. It would give a chance for public opinion on the nature of the controversy to be formed throughout the world and in the militant country. The latter is of great importance, for the moment war is declared argument about its merits is at once stifled. Passion runs too high for calm debate, and patriotism forces people to support their government. But a trial before an international tribunal would give time for discussion while emotion is not yet highly inflamed. Men opposed to war would be able to urge its injustice, to ask whether, after all, the object is worth the sacrifice, and they would get a hearing from their fellow citizens which they cannot get after war begins. The mere delay, the interval for consideration, would be an immense gain for the prospect of a peaceful settlement.
