Macgregor Warns Iran War Has Exposed the Limits of American Power and Left Israel in a Strategic Bind

A fragile diplomatic opening between Washington and Tehran has done little to calm the deeper anxiety spreading across the Middle East. Even as negotiators move toward a possible framework to end the war, the battlefield picture remains unsettled, the political pressure on President Trump is intensifying, and Israel’s position, once assumed to be dominant, is now being openly questioned by some of its harshest critics.

In a wide-ranging interview, retired U.S. Army Col. Douglas Macgregor delivered one of his bluntest assessments yet of the war, arguing that the United States has failed to achieve its core objectives against Iran and may now be looking for a way out of a conflict that has grown too costly, too complex and too dangerous to sustain.

The headline surrounding the discussion was dramatic: Iran had struck Israel hard, with claims circulating of heavy Israeli military casualties, including more than 200 soldiers and numerous senior commanders. Those figures remain contested and have not been independently confirmed by major Western outlets. But Macgregor’s broader argument did not depend solely on casualty counts. His point was larger: Iran, in his view, has survived the military campaign, Israel has failed to impose its strategic will, and the United States is discovering that air power and sanctions cannot easily break a state with Iran’s depth, geography and history.

The immediate diplomatic dispute centers on the terms of a possible U.S.-Iran settlement. According to the discussion, Iran is seeking the release of frozen assets in stages, while Washington appears to be shifting language around maritime access and fees in the Strait of Hormuz. Issues that once seemed central to American and Israeli demands — Iran’s ballistic missile program, its regional allies and the so-called Axis of Resistance — appear to have moved off the main negotiating table, at least for now.

That, Macgregor suggested, is precisely why Israel is alarmed.

For Israel, the war was never only about uranium enrichment or maritime security. It was about permanently weakening Iran as a regional power. If Tehran emerges from the conflict with its government intact, its missile program functioning and its alliances with Hezbollah and other groups still alive, then Israel will have paid a steep price without achieving the strategic victory it sought.

Macgregor argued that the Trump administration has been pulled between two opposing forces. On one side are Gulf states, energy markets and American voters who want the war to end. On the other are Israel, pro-Israel donors and hawkish figures in Washington who believe any deal that leaves Iran standing is a defeat.

His most controversial claim was that Israeli Prime Minister Benjamin Netanyahu still holds extraordinary influence over Trump’s Middle East policy. Macgregor described the president as a man who may want to end the conflict but is constrained by political forces that demand a victory for Israel. Whether one accepts that assessment or not, the tension is visible: Trump has alternated between saying Iran wants a deal and warning that the United States may have to “finish the job.”

That phrase — “finish the job” — carries enormous weight. In Macgregor’s interpretation, earlier objectives have already failed. The hope of stirring mass revolt inside Iran failed. The idea of decapitating the Iranian leadership failed to collapse the state. Weeks of bombing damaged infrastructure, killed officials and disrupted operations, but did not force surrender. What remains, he warned, is the most dangerous option of all: the destruction of Iran as a functioning society.

Macgregor dismissed that possibility as strategically impossible and morally reckless. Iran, he said, is not a fragile artificial state that can be shattered by removing a few leaders. It is a civilizational state with thousands of years of continuity, a large population, difficult terrain and a political culture shaped by endurance under pressure.

“Iran cannot be conquered,” he argued.

That sentence sits at the center of his analysis. The United States can bomb Iran. Israel can kill commanders. Western intelligence agencies can support covert operations. But conquering Iran would require a level of mobilization that America has neither the manpower nor the political will to undertake. There will be no draft, no million-man expeditionary army, no industrial mobilization on the scale required for occupation. Without a ground campaign, Macgregor said, airstrikes can only create temporary paralysis. They cannot impose a new political order.

That critique extends beyond Iran. Macgregor used the war to revisit a long line of American military disappointments: Korea, Vietnam, Iraq and Afghanistan. In his telling, the United States has repeatedly confused tactical success with strategic victory. In 1991, the U.S. military defeated Saddam Hussein’s army because Iraq was configured for an American-style war. But later campaigns showed the limits of force when political objectives were vague, unrealistic or driven by outside agendas.

Iran, he said, is not Iraq in 1991. It is not a conventional army waiting in the desert to be destroyed. Its defenses are dispersed, hardened and tied to a regional network of missiles, drones, proxies, satellites and asymmetric tools. Even if tunnel entrances are collapsed, they can be reopened. Even if ships are hit, other assets remain. Even if leaders are killed, institutions adapt.

That is why Macgregor believes the war has damaged not only Iran and Israel, but the image of American military power itself.

The consequences may be most visible in the Persian Gulf. For decades, Gulf monarchies relied on the United States as the ultimate guarantor of security. But if Washington cannot decisively defeat Iran — and if its military presence makes the region more vulnerable to missile attacks, oil shocks and infrastructure disruption — Gulf capitals may begin looking elsewhere. China, Macgregor argued, is already positioned to benefit. It has money, energy demand, diplomatic reach and a growing reputation as the central engine of global economic stability.

In his view, the war has accelerated a shift already underway: away from a U.S.-dominated order and toward a multipolar system in which China plays the role of indispensable economic partner.

But Macgregor’s warning was not limited to geopolitics. Some of his starkest remarks focused on the American economy. He argued that war in the Gulf is feeding inflation, pressuring oil markets and forcing Washington to use emergency petroleum reserves to suppress prices. If energy costs surge, supply chains weaken and consumer prices rise, the political consequences could reach far beyond foreign policy.

For American households, the war may not feel immediate at first. There is always a delay between disruption abroad and pain at home. But Macgregor warned that the lag should not be mistaken for safety. Energy is not only gasoline. It affects fertilizer, aviation fuel, shipping, manufacturing, food costs and industrial production. A prolonged crisis in the Gulf could move through the economy in waves.

That is where he believes Trump’s political danger truly lies. The president, he argued, will not be punished by voters for failing to destroy Iran. Most Americans do not want another major war in the Middle East. But Trump could be badly damaged if the war contributes to inflation, shortages, recession or financial instability.

The issue, Macgregor said, is legitimacy. Americans have grown used to the idea that elections change personalities but not policy. They see wars continue, deficits rise, industries weaken and living costs climb no matter which party wins. That perception is dangerous in a society already marked by inequality and distrust.

If fuel, food and jobs become insecure, public anger could move quickly from frustration to unrest.

Macgregor invoked historical examples to make the point. Empires and old regimes often appear stable until they suddenly are not. The Romanovs, Habsburgs, Hohenzollerns and Ottomans all seemed permanent before World War I shattered them. His warning was not that America is destined for the same fate, but that leaders should not assume stability is automatic.

That is why he urged Washington to end the war now rather than “tempt fate.” In his telling, the United States has already achieved the maximum damage it can realistically impose without escalating into something far worse. Continuing the conflict would not produce victory. It would deepen the crisis.

Macgregor also connected the Iran war to Ukraine and Taiwan, arguing that Washington is overextended across multiple theaters. Weapons stockpiles are strained. Hypersonic missile programs lag behind competitors. Drone defense remains inadequate. The U.S. Navy is built around expensive legacy platforms increasingly vulnerable to missiles, mines and unmanned systems. Meanwhile, Russia and China have studied American methods and developed cheaper ways to deny access to U.S. forces.

His assessment of Taiwan was especially striking. He gave Trump credit for recognizing the basic geographic reality that Taiwan sits close to China and thousands of miles from the United States. A war there, he argued, would be fought on China’s doorstep, not America’s. The lesson from Iran, in his view, is that distance matters, logistics matter and adversaries cannot be wished into weakness.

Macgregor’s critics would say he overstates American decline and underestimates the resilience of U.S. alliances. They would also argue that Israel still possesses one of the region’s most capable militaries and that Iran has suffered severe losses. But even critics may struggle to dismiss the central question he raises: what exactly is the strategy?

If the goal was to prevent Iran from becoming a nuclear-armed state, diplomacy may still be necessary. If the goal was regime change, the war has not delivered it. If the goal was to secure the Gulf, the conflict instead endangered energy flows. If the goal was to strengthen Israel, the result may be a more isolated Israel facing renewed pressure in Lebanon, Gaza and across the region.

For now, the United States appears caught between escalation and retreat. A deal with Iran could stabilize markets and reduce the risk of regional collapse, but it would likely be attacked by Israel and hawks in Washington as appeasement. A renewed military campaign could satisfy those demanding a show of strength, but it would risk a broader war that America may not be able to control.

Macgregor’s conclusion was simple and severe: the United States should leave the Persian Gulf conflict before it becomes a disaster not only for the region, but for America itself.

The war, he argued, has already revealed the limits of coercive power. Iran has not collapsed. Israel has not secured the decisive victory it wanted. The Gulf is reconsidering its dependence on Washington. China is gaining influence. American voters may soon feel the economic consequences.

In Washington, the debate is often framed as a question of toughness: whether Trump will stand firm, whether Iran will bend, whether Israel will accept a deal. But Macgregor sees a different test. For him, the question is whether the United States can still recognize when a war no longer serves its national interest.

Ending the conflict would be politically painful. It could look like retreat. It could anger powerful allies. It could expose the limits of American leverage. But continuing the war, he warned, could be far more costly.

The choice before Washington is no longer between victory and compromise. It is between compromise and a widening crisis whose consequences may be felt not only in Tehran, Tel Aviv and Beirut, but in American homes, gas stations, grocery stores and polling booths.

That is the warning Macgregor is trying to deliver: the Middle East war is no longer just a Middle East war. It has become a test of whether American power can adjust to reality before reality imposes the adjustment itself.
