The Iran war revealed the U.S.-Israel relationship so limits Washington’s strategic choices that the United States became the aggressor in a war advancing Israeli priorities over American interests.
For decades, the U.S.-Israel alliance was defended in Washington as an unquestionable strategic good. Israel was described as America’s most dependable partner in the Middle East, a force multiplier for U.S. power, and a democratic outpost in a hostile region. The Iran war stripped that language of credibility. It exposed not a durable strategic asset, but an increasingly costly strategic liability.
An ally becomes a liability when defending it leaves the patron weaker, less credible, and more constrained than before. That is the test that now matters. By that standard, the threshold has been crossed. Washington absorbed the costs of war and failed to achieve its goals. It emerged strategically weaker, while the alliance itself became more dangerous.
The gravest point is not only that the United States failed in the war, but that it did so in a conflict it should never have entered. While Washington did not just support an ally under pressure, it became the aggressor against a sovereign state with one of the world’s oldest civilizational histories. This action was not taken in response to an invasion of American territory, but rather during ongoing negotiations and in pursuit of a regional logic serving Israeli priorities over American interests. Although Israeli pressure may have narrowed Washington’s choices, it did not absolve the United States of its responsibility. Ultimately, the United States chose to attack, exposing how far this alliance now distorts American strategy.
That distortion did not arise overnight. One of John Mearsheimer’s central arguments is that the old American rationale for deep involvement in the Middle East—oil and the balance of power—has receded. The U.S.-Israel relationship has become the real driver of regional policy. He goes further, arguing that when Israeli and American interests diverge, Washington still bends toward Israel due to domestic political pressure and the influence of the pro-Israel lobby. Whether one accepts that thesis or not, the Iran war made one thing unmistakable: Washington was not acting with strategic independence. It operated within a structure of entrapment.
The entrapment became visible when the war’s theory of victory collapsed. The campaign was sold as short, sharp, and decisive. The promise was familiar: decapitate Iranian leadership, shatter the regime, trigger internal collapse, and force surrender or regime change. However, once that quick-win fantasy failed, the war became exactly what Mearsheimer warned: a war of attrition. From that point on, the strategic logic shifted in Iran’s favor. The United States had no serious ground option, could not bring naval power close enough to apply decisive pressure, and faced damaged or vulnerable regional bases, aircraft losses, and munitions depletion. Thus, a war meant to dramatize American strength instead revealed the limits of American coercion.
Iran, meanwhile, retained the leverage that mattered most. It could threaten the Strait of Hormuz, pressure Gulf infrastructure, and inflict pain not just on its immediate enemies but also on the global economy. That meant time worked against Washington. The longer the conflict continued, the worse America’s position became. What started as a demonstration of resolve began to look like a strategic trap. Only two exits appeared: escalate into a wider conflict with no clear victory, or concede and expose the original gamble as a failure. That is what it means to play a losing hand.
The war was self-defeating in the clearest way. It produced no regime change, no end to Iranian enrichment, no elimination of Iranian missile power, and no rupture in Iran’s ties to Hezbollah, Hamas, or the Houthis. Instead, it left Iran bloodied but defiant, still armed, and still regionally important. In some respects, Iran became more strategically relevant because its leverage is now undeniable. If a war starts with maximal goals and ends with the adversary still standing, armed, and able to impose costs, then it has not failed just tactically. It has failed strategically.
For Israel, the outcome was worse. It did not eliminate its adversary or establish regional dominance. It did not solve the problem that justified escalation at the beginning. Instead, it deepened its dependence on the United States, which absorbed the political, strategic, and moral fallout. This is why the word liability matters. A liability is not just an ally that causes friction. It is one whose ambitions drag its patron into conflicts that leave the patron more exposed. By that definition, Israel is no longer helping the United States manage the Middle East. It is making America’s position harder to sustain.
The broader indictment goes beyond Iran. In Mearsheimer’s view, Gaza and Iran are not separate episodes; rather, they are connected fronts in a wider Israeli regional strategy: territorial expansion, removing populations from seized land, and weakening or fragmenting neighboring states that resist Israeli dominance. Although that is a highly contested claim, it matters because it links the wars into a single strategic picture. From this perspective, the conflicts are treated as a single crisis rather than isolated events. The United States is criticized not only for supporting Israel diplomatically but for materially enabling policies it publicly claims to oppose. When sovereignty matters only for some states, and aggression is condemned in one theater but rationalized in another, American credibility is not just weakened—it is hollowed out.
That hollowing-out is not only external. It reaches into American political life itself. The issue is not just what Washington does abroad; it is also what Americans are expected to excuse to keep the alliance politically untouchable. When the language of human rights becomes selective, and international law becomes conditional, public morality bends. The alliance then ceases to be merely a foreign-policy arrangement. It begins to deform the standards used to justify American power.
Defeats are never only military. Once a war goes badly, citizens respond as states do after failure: they look back to the causes. They ask who led them there, whose interests were served, and why warnings were ignored. At this point, Mearsheimer’s answer is blunt: Israel pushed Trump toward war with promises of a quick victory, then helped make a negotiated exit harder. Even those who find that view too broad will have trouble dismissing the likely political consequence. If more Americans come to believe Washington was led into a disastrous war for goals that were not its own, the alliance will enter a new and unstable phase in American political life.
There is one final danger. Failed wars do not always produce caution. Sometimes they radicalize the losing side. Mearsheimer’s darkest warning is that if Israel decides conventional force cannot stop Iran from reaching a nuclear threshold, it will push for more extreme escalation. Whether or not that prediction is accepted, the danger is serious. The United States is now tied to an ally that dragged it into a disastrous war and may respond to failure with even more recklessness.
The real scandal is not just that the Iran war failed. It is that the United States entered it and became the aggressor against a sovereign state for ends never fully its own. An alliance once seen as a source of American strength now operates as entrapment. That is why Israel no longer looks like a U.S. asset, but a U.S. liability.
