Human Action

The market economy involves peaceful cooperation. It bursts asunder when the citizens turn into warriors and, instead of exchanging commodities and services, fight one another.

The wars fought by primitive tribes did not affect cooperation under the division of labor. Such cooperation by and large did not exist between the warring parties before the outbreak of hostilities. These wars were unlimited or total wars. They aimed at total victory and total defeat. The defeated were either exterminated or expelled from their dwelling places or enslaved. The idea that a treaty could settle the conflict and make it possible for both parties to live in peaceful neighborly conditions was not present in the minds of the fighters.

The spirit of conquest does not acknowledge restraints other than those imposed by a power which resists successfully. The principle of empire building is to expand the sphere of supremacy as far as possible. The great Asiatic conquerors and the Roman Imperators stopped only when they could not march farther. Then they postponed aggression for later days. They did not abandon their ambitious plans and did not consider independent foreign states as anything else than targets for later onslaughts.

This philosophy of boundless conquest also animated the rulers of medieval Europe. They too aimed first of all at the utmost expansion of the size of their realms. But the institutions of feudalism provided them with only scanty means for warfare. Vassals were not obliged to fight for their lord more than a limited time. The selfishness of the vassals who insisted on their rights checked the king’s aggressiveness. Thus the peaceful coexistence of a number of sovereign states originated. In the sixteenth century a Frenchman, Bodin, developed the theory of national sovereignty. In the seventeenth century a Dutchman, Grotius, added to it a theory of international relations in war and peace.

With the disintegration of feudalism, sovereigns could no longer rely upon summoned vassals. They “nationalized” the country’s armed forces. Henceforth, the warriors were the king’s mercenaries. [p. 822]

The organization, equipment, and support of such troops were rather costly and a heavy burden on the ruler’s revenues. The ambitions of the princes were unbounded, but financial considerations forced them to moderate their designs. They no longer planned to conquer a whole country. All they aimed at was the conquest of a few cities or of a province. To attain more would also have been unwise politically. For the European powers were anxious not to let any one of them become too powerful and a menace to their own safety. A too impetuous conqueror must always fear a coalition of all those whom his bigness has frightened.

The combined effect of military, financial, and political circumstances produced the limited warfare which prevailed in Europe in the three hundred years preceding the French Revolution. Wars were fought by comparatively small armies of professional soldiers. War was not an affair of the peoples; it concerned the rulers only. The citizens detested war which brought mischief to them and burdened them with taxes and contributions. But they considered themselves victims of events in which they did not participate actively. Even the belligerent armies respected the “neutrality” of the civilians. As they saw it, they were fighting the supreme warlord of the hostile forces, but not the noncombatant subjects of the enemy. In the wars fought on the European continent the property of civilians was considered inviolable. In 1856 the Congress of Paris made an attempt to extend this principle to naval warfare. More and more, eminent minds began to discuss the possibility of abolishing war altogether.

Looking at conditions as they had developed under the system of limited warfare, philosophers found wars useless. Men are killed or maimed, wealth is destroyed, countries are devastated for the sole benefit of kings and ruling oligarchies. The peoples themselves do not derive any gain from victory. The individual citizens are not enriched if their rulers expand the size of their realm by annexing a province. For the people wars do not pay. The only cause of armed conflict is the greed of autocrats. The substitution of representative government for royal despotism will abolish war altogether. Democracies are peaceful. It is no concern of theirs whether their nation’s sovereignty stretches over a larger or smaller territory. They will treat territorial problems without bias and passion. They will settle them peacefully. What is needed to make peace durable is to dethrone the despots. This, of course, cannot be achieved peacefully. It is necessary to crush the mercenaries of the kings. But this revolutionary war of the people against the tyrants will be the last war, the war to abolish war forever. [p. 823]

This idea was already dimly present in the minds of the French revolutionary leaders when, after having repelled the invading armies of Prussia and Austria, they embarked upon a campaign of aggression. Of course, under the leadership of Napoleon they themselves very soon adopted the most ruthless methods of boundless expansion and annexation until a coalition of all European powers frustrated their ambitions. But the idea of durable peace was soon resurrected. It was one of the main points in the body of nineteenth-century liberalism as consistently elaborated in the much abused principles of the Manchester School.

These British liberals and their continental friends were keen enough to realize that what can safeguard durable peace is not simply government by the people, but government by the people under unlimited laissez faire. In their eyes free trade, both in domestic affairs and in international relations, was the necessary prerequisite of the preservation of peace. In such a world without trade and migration barriers no incentives for war and conquest are left. Fully convinced of the irrefutable persuasiveness of the liberal ideas, they dropped the notion of the last war to abolish all wars. All peoples will of their own accord recognize the blessings of free trade and peace and will curb their domestic despots without any aid from abroad.

Most historians entirely fail to recognize the factors which replaced the “limited” war of the ancient regime by the “unlimited” war of our age. As they see it, the change came with the shift from the dynastic to the national from of state and was a consequence of the French Revolution. They look only upon attending phenomena and confuse causes and effects. They speak of the composition of the armies, of strategical and tactical principles, of weapons and transportation facilities, and of many other matters of military art and administrative technicalities.1  However, all these things do not explain why modern nations prefer aggression to peace.

There is perfect agreement with regard to the fact that total war is an offshoot of aggressive nationalism. But this is merely circular reasoning. We call aggressive nationalism that ideology which makes for modern total war. Aggressive nationalism is the necessary derivative of the policies of interventionism and national planning. While laissez faire eliminates the causes of international conflict, government interference with business and socialism creates conflicts for [p. 824]

which no peaceful solution can be found. While under free trade and freedom of migration no individual is concerned about the territorial size of his country, under the protective measures of economic nationalism nearly every citizen has a substantial interest in these territorial issues. The enlargement of the territory subject to the sovereignty of his own government means material improvement for him or at least relief from restrictions which a foreign government has imposed upon his well-being. What has transformed the limited war between royal armies into total war, the clash between peoples, is not technicalities of military art, but the substitution of the welfare state for the laissez-faire state.

If Napoleon I had reached his goal, the French Empire would have stretched far beyond the limits of 1815. Spain and Naples would have been ruled by kings of the house of Bonaparte-Murat instead of kings of another French family, the Bourbons. The palace of Kassel would have been occupied by a French playboy instead of one of the egregious Electors of the Hesse family. All these things would not have make the citizens of France more prosperous. Neither did the citizens of Prussia win anything from the fact that their king in 1866 evicted his cousins of Hanover, Hesse-Kassel and Nassau from their luxurious residences. But if Hitler had realized his plans, the Germans expected to enjoy a higher standard of living. They were confident that the annihilation of the French, the Poles, and the Czechs would make every member of their own race richer. The struggle for more Lebensraum was their own war.

Under laissez faire peaceful coexistence of a multitude of sovereign nations is possible. Under government control of business it is impossible. The tragic error of President Wilson was that he ignored this essential point. Modern total war has nothing in common with the limited war of the old dynasties. It is a war against trade and migration barriers, a war of the comparatively overpopulated countries against the comparatively underpopulated. It is a war to abolish those institutions which prevent the emergence of a tendency toward an equalization of wage rates all over the world. It is a war of the farmers tilling poor soil against those governments which bar them from access to much more fertile soil lying fallow. It is, in short, a war of wage earners and farmers who describe themselves as underprivileged “have-nots” against the wage earners and farmers of other nations whom they consider privileged “haves.”

The acknowledgment of this fact does not suggest that victorious wars would really do away with those evils about which the aggressors complain. These conflicts of vital interests can be eliminated [p. 825] only by a general and unconditional substitution of a philosophy of mutual cooperation for the prevailing ideas of allegedly irreconcilable antagonisms between the various social, political, religious, linguistic, and racial subdivisions of mankind.

It is futile to place confidence in treaties, conferences, and such bureaucratic outfits as the League of Nations and the United Nations. Plenipotentiaries, office clerks and experts make a poor show in fighting ideologies. The spirit of conquest cannot be smothered by red tape. What is needed is a radical change in ideologies and economic policies.
