In a world of international anarchy, law-based counter-terrorism is never just about strategy, tactics, or doctrine. Whatever an insurgency’s specific features, this critical arena of national security planning should remain intellect-based and logic-centered.

For Israel in the Islamic Middle East, this means an ongoing awareness of enemy concepts of death. It signifies, among other things, that Israel’s counter-terrorism planners ought continuously to bear in mind the primacy of an historically under-examined form of geopolitical power.

This neglected form of power, abstract but incomparable, is “power over death” — meaning, in what manner should have jihadi promises of immortality been affected by the Assad regime collapse in Syriaand the still-unresolved Gaza War?

“An immortal person,” says Jewish philosopher Emmanuel Levinas, “is a contradiction in terms.” Accordingly, any promise of immortality to jihadi terrorists will be densely problematic. It will, however, still resonate among those many insurgents who routinely prefer mystery to reason.

Assuming that others use decision-making rationality often make sense in explaining world politics, but there remain enough significant exceptions to temper any mundane generalities.

If Israel’s national decision-makers were to survey the prevailing configuration of global jihadi terrorist organizations (Sunni and Shiite) from a suitably- augmented analytic standpoint, the nexus between “martyrdom operations” and “life-everlasting” could become more conspicuous and understandable.

At that point, Israel’s national security planners could begin to place themselves in a better position to deter murderous hostage-takers and suicide-bombers, in microcosm (i.e., as individual human terrorists) and in macrocosm (i.e., as law-violating organizations or states that support the terrorist microcosm).

Those jihadi insurgents who seek to justify gratuitously violent attacks on Israelis in the name of “martyrdom” are acting contrary to codified and customary international law.

All insurgents, even those who passionately claim “just cause,” must still satisfy longstanding jurisprudential limits on permissible targets and levels of violence. Moreover, as a binding matter of law, such limits can never be tempered by any actively contending claims of religious faith. Under law, Palestinian claims of insurgency “by any means necessary” remain nothing more than an empty witticism.

Under established rules, even the allegedly “sacred” rights of insurgency always exclude any deliberate targeting of civilians or any intentional use of force to inflict unnecessary suffering. When Hamas terrorists kidnapped and beheaded Israeli infants on October 7, 2023, they were acting not on behalf of sovereignty or self-determination, but rather to cultivate the grotesque pleasures of a lascivious barbarism.

Law and strategy are interrelated. At the same time, they remain analytically distinct. The legal “bottom line” is unambiguous: Violence becomes terrorism whenever “political” insurgents murder or maim noncombatants, whether with guns, knives, bombs or automobiles. Always irrelevant to assessments of “just means” (jus in bello) is whether the expressed cause of terror-violence is just or unjust (jus ad bellum). Under the universal “law of nations,” unjust means used to fight for allegedly just ends are still law-breaking ipso facto.

Sometimes, Israel’s martyrdom-seeking jihadi foes advance the supposedly legal argument of tu quoque. This argument stipulates that because “the other side” is guilty of similar, equivalent or even greater criminality, “our side” is innocent of any wrongdoing.

Jurisprudentially, any such argument is disingenuous and incorrect, especially after landmark legal judgments by the Nuremberg (Germany) and Far East (Japan) ad hoc tribunals. Historically, tu quoque is always an immutably discredited posture.

For conventional armies and insurgent forces, the right to use military force can never supplant “peremptory” rules of humanitarian international law. Nonetheless, without a scintilla of law-based evidence, supporters of jihadi terror-violence against Israeli noncombatants continuously insist that “ends justify means.”

Leaving aside the ordinary ethical standards by which any such argument should be dismissed on its face, ends can never justify means in the law of armed conflict. Indeed, there can be no authoritative argument against this civilizing affirmation.

Witless banalities of politics ought never be taken as valid expectations of international law. In such law, whether codified or customary, one person’s terrorist can never be another’s “freedom-fighter.”

It’s really not complicated. Whenever an insurgent group resorts to unjust means, its actions constitute terrorism. Even if adversarial claims of a hostile controlling power could be plausible or acceptable (e.g., relentless Palestinian claims concerning an Israeli “occupation”), corollary claims of entitlement to “any means necessary” remain false.

Recalling Hague Convention No. IV: “The right of belligerents to adopt means of injuring the enemy is not unlimited.”

What about Israeli attacks on Gaza targets? Though Israel’s bombardments of Gaza have spawned multiple Palestinian casualties, the legal responsibility for these harms lay entirely with Hamas “perfidy” or “human shields.” While Palestinian casualties were always unwanted, inadvertent and unintentional, Israeli civilian deaths and injuries were always the result of jihadi criminal intent or “mens rea.”

International law does not provide an intuitive or subjective set of standards.  This law has determinable form and content. Therefore, it can never be casually invented or reinvented by terror groups to justify selective adversarial interests. This is especially the case when inhumane terror-violence intentionally targets a designated victim state’s most fragile and vulnerable civilians. Murdering captive infants is never defensible. Never.

National liberation movements that fail to meet the test of just means can never be protected as lawful or legitimate in themselves. Even if relevant law were to accept the questionable argument that jihadi terror groups had fulfilled all valid criteria of “national liberation,” these groups would still fail to satisfy equally significant jurisprudential standards of distinction, proportionality, and military necessity.

These standards were specifically applied to insurgent or sub-state organizations by the common Article 3 of the four Geneva Conventions of 1949, and (additionally) by the two 1977 Protocols to these Conventions.

There is more. Standards of “humanity” remain binding upon all combatants by virtue of the broader norms of customary and conventional international law, including Article 1 of the Preamble to the Fourth Hague Convention of 1907. This rule, commonly called the “Martens Clause,” makes “all persons” responsible for the “laws of humanity” and for associated “dictates of public conscience.” There can be no exceptions to this universal responsibility.

Under international law, terrorist crimes mandate universal cooperation in both apprehension and punishment. As punishers of “grave breaches” under international law, all states are expected to search out and prosecute or extradite individual terrorists. This is emphatically true for the United States, which incorporates international law as the “supreme law of the land” at Article 6 of the Constitution.

For the foreseeable future, jihadi “martyrs” could present an incrementally existential threat to Israel. If these criminals should ever get their hands on usable fissile materials, however, this threat could become more immediately existential. This does not mean that terrorists would necessarily require a “chain-reaction” nuclear explosive, but only the essential ingredients for an advanced radiation dispersal device.

In a worst case scenario, jihadi use of radiation dispersal weapons against Israel could spur Iran into protracted and enlarged military conflict with Israel. At that unpredictable point, Israel’s policy considerations of adversarial “last things” could become all-important.

In essence, for Israel, a jihadist enemy that links terror-violence to faith-based hopes of immortality could pose an incomparable threat. To suitably deter this fearsome peril, Israel’s national security planners should more expressly examine all strategic, geographic, and legal dimensions of the problem. For these science-based planners, jihadi searches for “power over death” ought immediately to become a subject of highest policy urgency.
