If reports are accurate that U.S. officials warned Iran — through intermediaries — that Israel might target senior Iranian leaders involved in negotiations with Washington, the disclosure would be extraordinary. The subsequent collapse of those negotiations only underscores the larger issue: Why did Washington believe preserving Iran’s negotiators served American interests while Israel reportedly viewed them as legitimate wartime targets? That question exposes a widening divide over Iran — and perhaps over the meaning of security itself.
The United States and Israel are not enemies, and their alliance is not collapsing. Military cooperation remains deep, intelligence ties remain extensive and both countries continue to view Iran as a dangerous adversary. But alliances can remain strong even as their strategic assumptions begin to diverge.
For decades, American foreign policy has assumed that hostile regimes need not become friendly to become manageable. If diplomacy, economic pressure and military deterrence can alter a government’s behavior, Washington has generally accepted its continued existence. Applied to Iran, that means preventing a nuclear weapon, reducing regional tensions and protecting global commerce. Those are entirely legitimate objectives for a global power.
Israel’s outlook has changed more fundamentally. Oct. 7 convinced many Israelis that regimes openly committed to Israel’s destruction cannot be treated as ordinary geopolitical rivals whose behavior can simply be managed over time. Deterrence may postpone conflict, but it cannot resolve an ideology dedicated to eliminating the Jewish state.
Iran is the clearest test. Nuclear agreements expire. Sanctions are lifted and reimposed. Military capabilities can be rebuilt. But a regime that arms Hezbollah, Hamas, Palestinian Islamic Jihad and other terrorist organizations while embracing Israel’s destruction remains a strategic threat regardless of temporary diplomatic accommodations.
That is why Washington and Jerusalem now define success differently. The collapse of the recent memorandum of understanding changes the circumstances, not the disagreement. For Washington, a constrained Iran may be an acceptable outcome. For Israel, it may be only an intermission before the next confrontation.
This is not merely a dispute over negotiations or assassination targets. It reflects two competing theories of security. One assumes hostile regimes can be contained if their capabilities are limited and the costs of aggression remain high. The other holds that regimes driven by a permanent ideological commitment to conflict will eventually exploit any opportunity to rebuild.
The implications extend well beyond Iran. Intelligence cooperation becomes more complicated when allies pursue different endgames. Adversaries look for opportunities to exploit perceived divisions. Political trust erodes when each ally concludes that the other has drawn different lessons from the same war.
None of this means the United States is abandoning Israel or that Israel is rejecting its most important ally. The real issue is larger than any single ceasefire or memorandum of understanding. Until Washington and Jerusalem once again share the same vision of Iran’s end state, each new diplomatic initiative will reopen the same strategic debate.
Friends can disagree over tactics. Allies can survive sharp policy disputes. But enduring alliances require agreement not only about how wars end, but about the peace they hope to secure. If America and Israel increasingly answer that question differently, the challenge will not be one failed negotiation. It will be preserving a strategic partnership built on a common understanding of what lasting security requires.
