“Ha-ba lehargecha hashkem lehargo” (אם בא להורגך השכם להורגו) is a Talmudic maxim from Sanhedrin 72a instructing that if someone actively seeks to take your life, you are permitted—and often obligated—to kill them first in self-defense.

For forty seven years Iran’s leaders have declared their intention to erase Israel, bring death to America, and export their revolution through militias, missiles, and martyrdom. Believe them!

War is ugly. Jews, of all people, know this better than most. Our prayers plead for peace three times a day.

When the President of the United States—whether one admires him or despises him—stands before the intelligence briefings and hears the phrase “imminent threat,” he is standing, whether he knows it or not, in the shadow of that Talmudic principle.

The phrase “imminent threat” is bureaucratic and dull. But Jews raised on Talmud know that danger is not decided by paperwork. The rabbis used a different word: rodef — the pursuer. If someone runs at you to kill, the law expects you to stop him before he succeeds. That blunt rule matters when the pursuer is not a single man with a knife but a regime building weapons and proxies with open hostility toward your country.

The medieval giant Maimonides—the Rambam—codifies the law of the rodef with brutal clarity. If a pursuer is chasing an innocent person to kill him, anyone witnessing it is obligated to stop the pursuer, even with lethal force if necessary.

Notice what Rambam does not require.

He does not require that the pursuer fire the gun first. He does not require that the victim be bleeding on the ground. The law intervenes before the murder is completed.

Iran is the free world’s enemy. For decades its leaders have supported militias, funded terrorist groups, and promoted a revolutionary agenda hostile to American interests and to allies in the region. That pattern — talk of destruction mixed with concrete steps to increase capability — is the modern equivalent of a pursuer drawing a blade. Treating such a pattern as mere rhetoric is wishful thinking, not strategy.

The halachic rule of the rodef does not demand absolute proof before action. Medieval authorities like Maimonides made that clear: you are not required to wait until the murderer’s hand strikes you. The law favors preemption when delay would mean inevitable harm. Applied to statecraft, the logic is straightforward. Waiting for an attack to be carried out before responding is morally and practically perilous.

Democratic leaders face an impossible calculus. They do not have prophecies; they have intelligence — incomplete, messy, often contested — and the obligation to protect their people. When the question is whether to act now or to risk catastrophe later, prudence argues for preventing a clear, growing danger rather than deferring until it is undeniable. That is uncomfortable, and it will earn criticism; history often rewards the patient, not the preventative. But history also punishes those who sleep through obvious threats.

Critics accuse leaders who act early of recklessness. That charge ignores a second possibility: that the action prevented a catastrophe and therefore looks unnecessary in hindsight. Preventive measures rarely gain monuments. They gain headlines and political attacks. Still, the moral test is not the applause of the day but whether the leader upheld the duty to protect the nation and its allies.

Jewish tradition values peace deeply, but it is not pacifist. Our texts are realistic about power and survival. The Maccabees and other Jewish leaders fought when survival demanded it. Saying “war is terrible” is not the same as saying “we must refuse to act when facing a real, growing threat.” Sometimes the moral choice is the hard choice.

So when a president hears “imminent threat” about a hostile, nuclear-capable regime that funds proxies and openly seeks regional dominance, the decision to act can be understood as the secular analogue of the halachic duty to stop the pursuer. That does not make war desirable. It does, however, make acting to prevent grave danger defensible in both moral and practical terms.

If this is the calculus a leader faces — incomplete intelligence, plausible catastrophe, and a duty to protect — then choosing to confront the threat is not swagger. It is responsibility. The preacher of delay may be sentimental; the leader who errs on the side of preventing mass harm may be judged harshly, but history will be the truer arbiter of which approach kept people alive.

Modern democracies suffer from a peculiar disease: the belief that danger must first be photographed, notarized, and confirmed by editorial boards like the New York Times before it becomes real.

But the Talmud does not think like that. The sages knew something about enemies. They lived under Rome, Persia, Byzantium—empires that rarely issued polite warning letters before persecution. Jewish survival depended on reading intentions early. The rabbis therefore developed a legal instinct that the modern West has largely forgotten: threats are judged by trajectory, not merely by the final act. When a regime builds the weapon, funds the proxy armies, and declares the coming war inevitable, the question is not whether danger exists. The question is how long you are willing to pretend otherwise.
