It is probable that Prussian militarism would have been already destroyed, or on the point of being so, if in the first part of the war the leaders of the Allied countries had not committed the three capital mistakes which to-day are generally acknowledged—the Balkan policy of 1915, the Dardanelles, the delay in sending reinforcements to Serbia.

It is evident that these three calamitous mistakes have entailed a considerable prolongation of the struggle and allowed Germany to build up the immense fortress which extends from Dunkirk on the north to Egypt on the south, and from the south of Riga to Bagdad (see the map on p. 72). In order to overthrow the mighty walls of this formidable fortress, the Allies must consent to sacrifices much greater and more prolonged than would have been necessary if the mistakes now generally acknowledged had not been committed. These sacrifices the Allied peoples accept with a devotion and heroism which will win the imperishable admiration of posterity. But just because the faults committed have lengthened the duration of the struggle, the leaders of the Allied countries are in duty bound to do everything they can to accelerate a complete victory. That victory would be considerably hastened by the accession of the forces, whether economic or military, of the still neutral countries which, though they are even yet not fully aware of it, would be directly endangered by the success of the Pangerman plan.

I have shown on p. 219 how a systematic propaganda of the Allies, taking as its text the temporary accomplishment of the Pangerman plot, might speedily demonstrate to neutrals the falsehood of the German sophistries by which they have been cajoled. The same propaganda should have for its second object to convince these neutrals that they have as much to gain as the Allies by the destruction of Prussian militarism and of the “Hamburg to the Persian Gulf” project. If once this were clearly demonstrated it would be both legitimate and possible to request of these neutrals that they should contribute, in the measure of their power, to the common task of saving the civilization of the world.

In order rapidly to secure practical results from a convincing propaganda, it is necessary to define very clearly what in the vast welter of the present struggle is the point of vital interest common to all the States of the World. As I have shown in the course of this book, what would provide Germany with the means of establishing her universal dominion would be the accomplishment, whether direct, or indirect, of her scheme “from Hamburg to the Persian Gulf.” On the other hand, I believe I have demonstrated that to prevent the accomplishment of that scheme it is enough, but it is necessary, that the Latin and Slav peoples of Austria-Hungary should be freed, once for all, from the yoke which Germany has imposed on them through the opportunity given her by the war. For if the majority of these peoples were to be combined as a State in place of Austria-Hungary, probably in a federal form, there would at once be set up in Central Europe an immovable barrier which would ensure the world against any revival of Pangerman aggression (see the map on p. 43). On the other hand, if the independence of the Slav peoples of Austria-Hungary were not secured against Berlin, the extension of Prussian militarism to the Balkans and Turkey would be inevitable; the Allied peoples would have made all their unheard-of sacrifices in vain, and the struggle against Prussianism would be bound to continue.

EUROPEAN STATES INTERESTED IN THE SOLUTION OF THE AUSTRO-HUNGARIAN QUESTION.

From these considerations it follows that the question of Austria-Hungary, just because its solution implies the downfall of the “Hamburg to the Persian Gulf” castle-in-the-air, constitutes the crucial point not only of the European problem, but of the whole problem which the Pangerman plan of universal domination raises for all civilized States. Consequently the solution of the question of Austria-Hungary, on the basis of the principle of nationalities, forms the bond of common interest not only between the belligerent Allies but also between all the still neutral States of the world who are threatened in any degree by the accomplishment of the scheme “from Hamburg to the Persian Gulf.”

The annexed maps show clearly the States of the world for which the solution of the question of Austria-Hungary has an interest greater or less in degree but substantially identical.

It is clear that if Germany could keep her hold permanently on Austria-Hungary, Russia would be constantly threatened. In consequence of the extension of Prussian militarism which would result therefrom, England would be forced to continue to maintain the formidable armaments which she has accepted only as a temporary measure. As for France, no restoration of Alsace-Lorraine could be lasting, if the vassal regiments of Austria-Hungary should give the government of Berlin, after a brief breathing-space, the power to wrench again from France the provinces which had been temporarily ceded. Belgium would be threatened for the same reason. As for Italy, German supremacy over Central Europe would be the end of all Italian hopes on the Adriatic, and of all Italian expansion over the Eastern Mediterranean. As for Serbia and Montenegro, that dominion would be a sentence of death without appeal. For Portugal, it would imply the loss of her territories beyond the sea in virtue of the consequences which would follow the achievement of the plan “from Hamburg to the Persian Gulf.”

But countries still neutral, such as Greece, Roumania[6], Holland, and Switzerland, at which the Pangerman musket is levelled point-blank, ought also to be convinced that their most solid interests, in complete harmony with their moral obligations to the cause of civilization, make it their duty to lend the Allies all the support they can, whether it be moral, economic, or military.
