The concept of a monkey trap is straightforward: food is placed inside a hole just large enough for an open hand to enter but too narrow for a clenched fist to withdraw. The monkey's reluctance to release the bait seals its fate, even as danger closes in. This analogy now frames the Trump administration's predicament in its war with Iran—the promised prize of victory remains just out of reach, yet letting go carries consequences the administration is unwilling to accept.

Ironically, the only remaining objective—reopening the Strait of Hormuz to unrestricted transit—was a condition that already existed before hostilities began. The strait is one of the world's most critical energy chokepoints: under normal conditions, roughly a fifth of global daily oil consumption passes through it, according to the U.S. Energy Information Administration. Now that Iran has seized effective control of the strait and closed it to traffic it deems unfriendly, that closure has become Iran's most potent source of leverage over the United States and its allies.

Iran has declared that as long as the war continues, no shipments of oil, natural gas, petrochemicals, helium, fertilizers, or other critical commodities will pass through—except for its own and select cargoes from friendly nations. Because these shipments represent significant shares of global supply, the strait's closure has driven prices sharply higher, with shortages already materializing in multiple regions worldwide. Iran has periodically threatened to close the waterway during past confrontations—including during the Iran–Iraq War of the 1980s, when attacks on commercial shipping in the Persian Gulf became known as the "Tanker War"—but this is the first sustained closure in decades.

Were the Trump administration to withdraw from the conflict, the move would be perceived as a concession of defeat—something President Donald Trump is determined to avoid. The ramifications of such an acknowledgment extend across four dimensions.

First, conceding that a country previously regarded as a second-rate military power can defeat the United States would embolden other actors to challenge American influence elsewhere, particularly in the South China Sea and Taiwan.

Second, political and financial backing from pro-Israel advocacy groups and major Republican donors would likely collapse. Third, losing a war that most Americans already opposed would reinforce public opposition and translate into damaging electoral outcomes in the November midterm elections. Fourth, such a loss would constitute a profound personal embarrassment for Trump, whose public persona is built on the image of a winner and who routinely labels his adversaries as losers.

A victory, by contrast, would presumably avert all four outcomes. It is worth recalling that at the outset of the war, American objectives were described as threefold: regime change in Iran, the elimination of its missile capabilities, and prevention of a nuclear-armed Iran. Reopening the Strait of Hormuz was not among the original goals because the waterway was already open to navigation. Today, the first three objectives appear unattainable. All that remains is the aim of restoring the strait to unfettered navigation, free of Iranian control or tolls.

Achieving even that limited goal, however, would require gaining control over most or all of Iranian territory. Iran has already demonstrated the capacity to launch missiles and drones from hundreds of miles away and strike targets—including the strait itself—with precision. Even if U.S. forces secured the shoreline and immediately adjacent inland areas around the strait, an undertaking that would be both dangerous and costly in lives and resources, they could not prevent Iran from continuing to attack shipping from positions deeper inland.

Compounding the difficulty, dwindling U.S. munitions stockpiles—both offensive and defensive—are making it increasingly difficult for the United States to protect its bases in the Persian Gulf region and to conduct strikes against Iran, particularly from positions outside Iranian airspace to avoid losses of American aircraft. Replenishing the high-technology munitions already expended during the war will require not months but years. Continuing offensive operations risks depleting the remaining low inventories of anti-missile systems and precision long-range ordnance.

The administration faces a stark set of options. It can press ahead offensively, risking exposure of the United States and its allies—including Israel—to greater damage as Iranian missiles and drones overwhelm depleted missile defenses. If Iranian energy infrastructure is targeted, Iran could retaliate by striking energy infrastructure across Israel and the Persian Gulf. Such reciprocal destruction would almost certainly trigger a global economic depression, driven by acute shortages of oil and natural gas that could not be resolved for years.

Alternatively, the administration could simply withdraw, thereby accepting Iranian control of the Strait of Hormuz and Iran's de facto dominance in Southwest Asia. Or it could maintain the existing embargo on Iran without advancing or retreating militarily—a posture that would lead to the same global economic depression over time as the strait remains closed.

The Trump administration thus finds itself in a predicament from which retreat seems politically impossible and advance seems militarily and economically perilous. Whether and when the president ultimately changes course is a question with implications for the entire planet.
