Today, wars rage in the Ukraine and Middle East. What attitude should libertarians adopt toward these wars? Is it consistent with libertarian principles to support whatever side you think has the better case? Can you urge that side to go all-out for victory? Murray Rothbard, the greatest of all libertarian theorists, did not think so. And this is true even if you have assessed the conflict correctly. Let’s look at what he says in his great book The Ethics of Liberty.
As you might expect, Murray doesn’t begin his analysis by taking conflicts between states as the starting point. He asks what individuals involved in a conflict could properly do in an anarcho-capitalist society. Here is what he says:
“Before considering inter-State actions, let us return for a moment to the pure libertarian stateless world where individuals and their hired private protection agencies strictly confine their use of violence to the defense of person and property against violence. Suppose that, in this world, Jones finds that he or his property is being aggressed against by Smith. lt is legitimate, as we have seen, for Jones to repel this invasion by the use of defensive violence. But, now we must ask: is it within the right of Jones to commit aggressive violence against innocent third parties in the course of his legitimate defense against Smith? Clearly the answer must be “No.” For the rule prohibiting violence against the persons or property of innocent men is absolute; it holds regardless of the subjective motives for the aggression. lt is wrong, and criminal, to violate the property or person of another, even if one is a Robin Hood, or is starving, or is defending oneself against a third man’s attack. We may understand and sympathize with the motives in many of these cases and extreme situations. We (or, rather, the victim or his heirs) may later mitigate the guilt if the criminal comes to trial for punishment, but we cannot evade the judgment that this aggression is still a criminal act, and one which the victim has every right to repel, by violence if necessary. In short, A aggresses against B because C is threatening, or aggressing against, A. We may understand C’s “higher” culpability in this whole procedure, but we still label this aggression by A as a criminal act which B has every right to repel by violence. To be more concrete, if Jones finds that his property is being stolen by Smith, Jones has the right to repel him and try to catch him, but Jones has no right to repel him by bombing a building and murdering innocent people or to catch him by spraying machine gun fire into an innocent crowd. If he does this, he is as much (or more) a criminal aggressor as Smith is. The same criteria hold if Smith and Jones each have men on his side, i.e. if “war” breaks out between Smith and his henchmen and Jones and his bodyguards. If Smith and a group of henchmen aggress against Jones, and Jones and his bodyguards pursue the Smith gang to their lair, we may cheer Jones on in his endeavor; and we, and others in society interested in repelling aggression, may contribute financially or personally to Jones’s cause. But Jones and his men have no right, any more than does Smith, to aggress against anyone else in the course of their “just war”: to steal others’ property in order to finance their pursuit, to conscript others into their posse by use of violence, or to kill others in the course of their struggle to capture the Smith forces. If Jones and his men should do any of these things, they become criminals as fully as Smith, and they too become subject to whatever sanctions are meted out against criminality. In fact, if Smith’s crime was theft, and Jones should use conscription to catch him, or should kill innocent people in the pursuit, then Jones becomes more of a criminal than Smith, for such crimes against another person as enslavement and murder are surely far worse than theft. Suppose that Jones, in the course of his “just war” against the ravages of Smith, should kill some innocent people; and suppose that he should declaim, in defense of this murder, that he was simply acting on the slogan, “give me Iiberty or give me death.” The absurdity of this “defense” should be evident at once, for the issue is not whether Jones was willing to risk death personally in his defensive struggle against Smith; the issue is whether he was willing to kill other innocent people in pursuit of his legitimate end. For Jones was in truth acting on the completely indefensible slogan: “Give me liberty or give them death” —surely a far less noble battle cry.”
Murray next argues that because you may never harm the innocent, nuclear war is always wrong, because there is no way of confining the damage these weapons do to legitimate targets. Murray makes this point unmistakably clear:
“lt has often been maintained, and especially by conservatives, that the development of the horrendous modern weapons of mass murder (nuclear weapons, rockets, germ warfare, etc.) is only a difference of degree rather than kind from the simpler weapons of an earlier era. Of course, one answer to this is that when the degree is the number of human lives, the difference is a very big one. But a particularly libertarian reply is that while the bow and arrow, and even the rifle, can be pinpointed, if the will be there, against actual criminals, modern nuclear weapons cannot. Here is a crucial difference in kind. Of course, the bow and arrow could be used for aggressive purposes, but it could also be pinpointed to use only against aggressors. Nuclear weapons, even “conventional” aerial bombs, cannot be. These weapons are ipso facto engines of indiscriminate mass destruction. (The only exception would be the extremely rare case where a mass of people who were all criminals inhabited a vast geographical area.) We must, therefore, conclude that the use of nuclear or similar weapons, or the threat thereof, is a crime against humanity for which there can be no justification. This is why the old cliché no longer holds that it is not the arms but the will to use them that is significant in judging matters of war and peace. For it is precisely the characteristic of modern weapons that they cannot be used selectively, cannot be used in a libertarian manner. Therefore, their very existence must be condemned, and nuclear disarmament becomes a good to be pursued for its own sake. Indeed, of all the aspects of liberty, such disarmament becomes the highest political good that can be pursued in the modern world. For just as murder is a more heinous crime against another man than larceny, so mass murder—indeed murder so widespread as to threaten human civilization and human survival itself-is the worst crime that any man could possibly commit. And that crime is now all too possible. Or are libertarians going to wax properly indignant about price controls or the income tax, and yet shrug their shoulders at or even positively advocate the ultimate crime of mass murder?”
