The moral questions raised in the preceding chapter have a direct bearing on the effectiveness of military power based on the National unit, or a group of National units, such as an Alliance. Military preponderance of the smaller Western National units over large and potentially powerful groups, like the German or the Russian, must necessitate stable and prolonged co-operation. But, as the present condition of the Alliance which fought the War shows, the rivalries inseparable from the fears and resentments of 'instinctive' nationalism, make that prolonged co-operation impossible. The qualities of Nationalism which stand in the way of Internationalism stand also in the way of stable alliances (which are a form of Internationalism) and make them extremely unstable foundations of power. The difficulties encountered by the Allies in taking combined action in Russia show that to this fundamental instability due to the moral nature of Nationalism, must be added, as causes of military paralysis, the economic disruption which reduces the available material resources, and the social unrest (largely the result of the economic difficulties) which undermines the cohesion even of the national unit. These forces render military predominance based on the temporary co-operation of units still preserving the Nationalist outlook extremely precarious and unreliable. CHAPTER V (pp. 142-168) PATRIOTISM AND POWER IN WAR AND PEACE: THE SOCIAL OUTCOME The greatest and most obvious present need of Europe, for the salvation of its civilisation, is unity and co-operation. Yet the predominant forces of its politics push to conflict and disunity. If it is the calculating selfishness of 'realist' statesmen that thus produces impoverishment and bankruptcy, the calculation would seem to be defective. The Balkanisation of Europe obviously springs, however, from sources belonging to our patriotisms, which are mainly uncalculating and instinctive, 'mystic' impulses and passions. Can we safely give these instinctive pugnacities full play? One side of patriotism--gregariousness, 'herd instinct'--has a socially protective origin, and is probably in some form indispensable. But coupled with uncontrolled pugnacity, tribal gregariousness grows into violent partisanship as against other groups, and greatly strengthens the instinct to coercion, the desire to impose our power. In war-time, pugnacity, partisanship, coerciveness can find full satisfaction in the fight against the enemy. But when the war is over, these instincts, which have become so highly developed, still seek satisfaction. They may find it in two ways: in conflict between Allies, or in strife between groups within the nation.
