The war has left behind it a great number of small wars or guerrillas. Most of them have their explanation in some ordinary excess of nationalism or revenge or greed. The Serbs, intoxicated with their new greatness, are still causing war in Albania and Montenegro. The Rumanians recently invaded Hungary, in spite of all the thunders of the Peace Conference, because they had been robbed by Austria-Hungary and wanted revenge and reparation. The Hungarians have alarmed all their neighbours and forced them into a defensive alliance, which now calls itself the "Little Entente." The Lithuanians and Poles have fought, but been reconciled by the mediation of the League of Nations. The Armenians have been massacred again, under the eyes of the French army of occupation in Cilicia, where they had gathered under a repeated guarantee of safety given by France and England. The Turkish Nationalists are holding out very unsuccessfully in the centre of Anatolia against a Greek army carrying out the directions of the Supreme Council. The Turkish peasants are increasingly reluctant to take arms again. The Koreans have helplessly declared their right to independence from Japan, and are apparently being reduced by a terrible persecution. These are the mere belated effervescence of the passions of the Great War. The hate and pride which are the basis of nationalism and which were so violently stimulated by the events of the war cannot be expected to die out at once. It was calculated a short time ago that there were twenty-seven "wars" of one sort or another in progress. But they will presumably simmer down as social conditions become more normal. It is interesting to observe that two of the greatest causes of war, according to the judgment of normal times, are now not actively operating. Before 1914, if one was asked to name the main causes of war, the answer would have been, first, competitive armaments, and, second, protective tariffs and the competition for markets. These causes will remain fully as dangerous for the future, but it so happens that none of the existing wars is directly due to either. I. ARMAMENTS In one sense, indeed, armaments are actually operating now as a cause of war. There are far too many firearms lying about. America, England, and France have made very lavish gifts or sales of lethal weapons to various bodies with whom they sympathized. And the arms have by no means always stayed in the place for which they were intended. Guns which we sent to Denikin were sold by corrupt officials to the Bolsheviks, and passed on by them to the Afghans to use against us on the Indian frontier. Such things cause some deaths and some laughter, but are not permanent evils.
