Judging Preemptive Attacks

Have Israeli and U.S. attacks been ethically justifiable?

It is worth underscoring that the Jewish tradition reluctantly justifies war and, in our time, only for self‑defense. Some sources, however, legitimate even preemptive wars for that purpose. How would that viewpoint apply to some of the contemporary instances of intervention?

Room for Disagreement

As one might expect, in some cases the application would be straightforward while in others it would be more ambiguous. In the latter cases, even those who have the same Jewish perspective on the general issue of preemptive war may disagree as to whether a given preemptive action is legitimate.

In many cases though, they would agree, and where they differ they would at least share the same universe of discourse so that they could argue intelligently about how to apply their shared values to the case at hand.

Clear Cases, Difficult Cases

Let us begin with some of the clearer cases. From the perspective of the Jewish value system, certainly Israel’s strike against Egypt on the first morning of the Six Day War was a justifiable act of self‑defense in view of Egypt’s bellicose words and actions in the prior weeks.

In light of the incessant rocket and terrorist attacks against Israel’s northern settlements, one could probably make the same case for the initial stages of Israel’s 1982 incursion into Lebanon, although probably not for the remainder of that affair. The Entebbe raid was similarly justifiable; citizens of Israel and other travellers on her aircraft had been kidnapped.

America’s strike against Libya was probably justifiable also, although the terrorist provocation for it, while likely in view of Libya’s past behavior, was not as publicly verifiable. All of these actions were, it seems to me, legitimately undertaken in the name of self‑defense.

American action in Chile, Grenada, Vietnam, El Salvador, and Nicaragua, and the Israeli bombing of Beirut are, from a Jewish point of view, much less defensible. The intervention in Chile in 1976 was at least restricted to nonmilitary means. Even so, its morality from a Jewish point of view is doubtful in light of the fact that the regime, communist though it was, did not immediately endanger the United States and, given its own internal weakness, probably would not have posed much of a threat over the long term either.
