The Catholic Church developed just-war theory, but the pontiff doesn’t seem to understand it.

Pope Francis reportedly warned Israeli President Isaac Herzog in a phone call that it is “forbidden to respond to terror with terror.” Assuming he meant this as a criticism of Israel’s efforts to defend itself against Hamas, one might dismiss it as the ill-informed opinion of a left-leaning politician. But the pope’s error is worth taking seriously, because he speaks with some authority on matters of war and peace. Catholic theology has shaped the Judeo-Christian “just war” theory that midwifed the modern laws of war.

If the pope believes there is a certain level of civilian casualties in Gaza that is per se impermissible, he is fundamentally wrong. That view, common though it is, conflicts with key just-war precepts that demand careful balancing of competing imperatives.

Just-war doctrine, while refined over the centuries, was largely developed within the Christian tradition by St. Augustine of Hippo in the fourth century. Augustine rejected primitive Christian pacifism and argued that war, waged in compliance with proper rules, is a necessary tool of ethical statecraft. Acknowledging the sanctity of human life and expressing concern about the harm inevitably caused by a clash of arms, just war’s principal role is to protect the innocent to the extent possible, a task that pacifism can’t accomplish.

Just-war precepts, as incorporated into the traditional laws of war, have two distinct components. The first, jus ad bellum, comprises the rules governing when force may be rightly used. These include just cause, legitimate authority, public declaration, proper intent, proportionality, use of arms as the last resort, and reasonable hope for success. Given Hamas’s longstanding resolve to destroy the Jewish state, the failure of several Israeli military campaigns over the years to deter the terror group, and the Oct. 7 massacre, Israel unquestionably meets these criteria.

The second component, jus in bello, encompasses the rules governing how force may be lawfully used, including at whom it may be directed. This component underwent considerable doctrinal refinement between the 17th and 19th centuries. On April 24, 1863, the U.S. became the first military power to promulgate a comprehensive jus in bello manual, known as the Lieber Code.

Combatants must comply with both jus in bello and jus ad bellum, and violations by one side don’t justify violations by the other. Yet defining a war crime isn’t a simple matter of counting bodies. The weighing of conflicting imperatives permeates every facet of just-war theory. Guiding this balancing is the principle of double effect, which holds that it is morally permissible to act in pursuit of a good goal even if doing so would produce unintended but foreseeable harm. This principle is undergirded by a broad proportionality requirement, which measures the totality of positive and negative consequences of prosecuting a given war.

Jus in bello law contains two basic principles. The principle of discrimination forbids deliberate attacks on civilians and civilian infrastructure. It is absolute and brooks no departures. The principle of proportionality holds that in attacking legitimate military targets—which include military facilities that Hamas has integrated into civilian infrastructure—combatants are permitted to cause unavoidable collateral damage to civilians and civilian infrastructure, provided the harm is proportional to the value of the legitimate military objectives being sought. Destroying Hamas qualifies as a paramount military objective.

The principle of proportionality has been traditionally applied with considerable flexibility, in part because balancing its imperatives depends on combat circumstances that involve complex technical matters that are inherently difficult to gauge.

The laws of war used to play no favorites. Since World War II, however, humanitarian organizations, led by the International Committee of the Red Cross, have sought to provide special privileges for national liberation movements, an imprecise term that could include Hamas. These organizations have also tried to dilute rules that classify as unlawful enemy combatants fighters who don’t bear arms openly, don’t wear distinctive uniforms, and don’t operate in military organizations that feature well-defined command structures. Those efforts have constrained the military flexibility of law-abiding powers.

Equating unintended and proportional collateral damage with terrorism, as Pope Francis apparently did, goes further. It undermines the right to self-defense, the cornerstone of the laws of war. If the characterization of Israel’s exercise of its right of self-defense as terrorism were to prevail, the laws of war, instead of reflecting the military imperatives of law-abiding powers, would give a decisive advantage to terrorists and rogue states.

This is particularly dangerous at a time when Hamas jihadists commit horrific war crimes and Russia attacks, tortures and rapes civilians and brutalizes prisoners of war. For rogue entities like these, war crimes aren’t a cruel aberration but an integral part of their battle plans.

The pope’s comments to Mr. Herzog amount to a rejection of just-war theory and an embrace of primitive pacifism. They fail to understand that what happens in Gaza won’t stay in Gaza. If the laws of war were rewritten to preclude law-abiding powers like Israel and the U.S. from defending themselves against lawless combatants like Hamas, Hezbollah and Iran, lawlessness would inevitably prevail.

Since the 1990s, Congress has maintained that Jerusalem should be recognized as Israel’s capital. Since Israel’s founding in 1948, presidents have stated that Jerusalem’s status can only be decided as part of a broader peace settlement. On Monday this dispute again reached the Supreme Court, and it offers the justices a unique opportunity to elucidate the proper way to resolve separation-of-power disputes between Congress and the executive.

Zivotofsky v. Kerry involves Menachem Zivotofsky, a 12-year-old Jerusalem-born American citizen. His parents want Israel identified as his birthplace on his passport. Section 214(d) of the Foreign Relations Authorization Act, Fiscal Year 2003, permits this choice, but the secretary of state refused to comply, listing Jerusalem alone as his place of birth. The secretary argues that the law violates established U.S. foreign policy and interferes with the president’s exclusive power to recognize foreign states and their territorial extent.

In the first round of this litigation, the U.S. Court of Appeals for the District of Columbia concluded that this contest presented a political question that the courts could not answer. The Supreme Court reversed that decision, explaining that however “political” the circumstances, the question was a straightforward one of constitutional law suitable for judicial resolution.

The D.C. Circuit reheard the case last year and concluded that section 214(d) is unconstitutional because the president has the exclusive authority to determine the territorial boundaries of foreign states, their capitals and their governments—at least for purposes of U.S. diplomatic intercourse.

This authority is based in clear constitutional text that gives the president the power “to receive Ambassadors and other public Ministers.” Although the court found this language ambiguous (relying instead on historical practice and Supreme Court statements that the president alone has the power to recognize a foreign state as sovereign), the framers used this language precisely and to a purpose.

Hamas claims that former president Jimmy Carter’s recent meeting with its leader, Khaled Meshal, marks its recognition as a “national liberation movement” — even though Hamas rockets fired from the Gaza Strip, which Hamas rules as an elected “government,” continue to rain down on Israel’s civilian population. While Hamas is clearly trying to bolster its legitimacy, the conflict along Israel’s southern border has a broader legal dimension — the question of whether, as a matter of international law, Israel “occupies” Gaza. The answer is pivotal: It governs the legal rights of Israel and Gaza’s population and may well set a legal precedent for wars between sovereign states and non-state entities, including terrorist groups such as al-Qaeda.

Israel’s critics argue that Gaza remains “occupied” territory, even though Israeli forces were unilaterally withdrawn from the area in August 2005. (Hamas won a majority in the Gazan assembly in 2006 and seized control militarily in 2007.) If this is so, Jerusalem is responsible for the health and welfare of Gazans and is arguably limited in any type of military force it uses in response to continuing Hamas attacks. Moreover, even Israel’s nonmilitary responses to Hamas-led terrorist activities — severely limiting the flow of food, fuel and other commodities into Gaza — would violate its obligations as an occupying power.

The critics should look no further than the U.S. to see what consequences can ensue.

By DAVID B. RIVKIN JR. And KARL R. MOOR

While the Israeli political scene is no stranger to strident criticisms directed at senior government officials and their policies, the recent attacks on Prime Minister Benjamin Netanyahu and Defense Minister Ehud Barak over their policies toward Iran are a dangerous luxury.

Numerous retired security officials who do not lack a private voice or influence within a small nation. including former Shin Bet head, Yuval Diskin, ex- Mossad chief, Meir Dagan, and Former IDF Chief of General Staff Gabi Ashkenazi, have launched broadsides against the current Israeli government’s dire assessments of the Iranian threat and the best ways of dealing with it.
