US-Iran conflict trapped in escalation cycle with no exit strategy in sight

Six months into an open war that began in late February, the United States and Iran find themselves repeating the same argument with the same outcome: threats, a moment of negotiation, a collapse, and then violence again. Neither side has found a way out, and the pattern shows no sign of breaking.

The cycle is visible in the details. In June, both countries signed a memorandum of understanding. Iran agreed to reopen the Strait of Hormuz—one of the world's most critical shipping lanes—in exchange for the US lifting its economic sanctions, unfreezing Iranian assets, and removing its military blockade. It seemed like a resolution. Within weeks, it was not. The Trump administration began routing merchant vessels through shipping lanes closer to Oman, waters that Iran did not control. Iran saw this as a violation of the agreement. On July 7, Iranian forces struck vessels using the southern route. The US responded with air strikes. The war resumed. At least 84 incidents involving damage to ships in the strait have been recorded between March and August alone.

President Trump's approach to the conflict follows a predictable rhythm. He has threatened massive destruction of Iranian infrastructure—ports, energy facilities, even "civilisation" itself—at least seven times. Then he reverses course, calling off strikes and suggesting a deal is near. Iran's leadership oscillates differently: sometimes engaging in direct talks or working through intermediaries, sometimes refusing to negotiate at all. The US military posture in the region has shifted just as erratically. A naval blockade announced in April was doubled down in May with Operation Project Freedom, designed to escort ships through the strait. That operation paused after two days. When the June agreement was reached, the blockade was formally lifted. When the agreement collapsed, it was reimposed.

The fundamental problem is that neither side can accept what the other side needs. Trump will not tolerate a strategic defeat that leaves Iran in effective control of the Strait of Hormuz, a waterway through which roughly one-third of global maritime trade passes. Yet accepting Iranian control was apparently what he signed up for in June—until the moment came to actually live with it. The alternative, from the American perspective, would be a massive ground invasion of Iran, boots on the ground, a military commitment that carries enormous political and military risk, particularly in an election year.

Iran's calculation is different but equally rigid. The regime views this conflict as existential. Control of the Strait of Hormuz is not merely a negotiating point; it is the country's primary leverage against a much more powerful adversary. The new supreme leader, Mojtaba Khamenei, has recently appointed hardliners to six top security and defense positions, signaling that Tehran is preparing for a long war, not a quick settlement. One of these appointees, Mohsen Rezaei, a former commander in the Islamic Revolutionary Guard Corps, stated in April that he would welcome a US ground invasion because Iran could take American hostages and demand a billion dollars per person. This is not the language of a regime seeking compromise.

For Iran's leadership, a prolonged external conflict may actually serve internal purposes. The country is economically stressed and unpopular with significant portions of its own population. A long war against the United States provides a unifying external threat, a reason for citizens to rally behind the regime rather than question it. Trump assumes that repeated economic and military pressure will force Iran to capitulate. Instead, the pressure appears to be hardening Iranian resolve.

The question of how this cycle breaks has no clear answer. Theoretically, it could end when one side becomes so exhausted—politically and militarily—that ending the war becomes more important than winning it. But that threshold may still be months or years away. In the meantime, both sides will likely continue the pattern: demands that cannot be met, agreements that collapse, and military strikes that prove nothing except that neither side is willing to back down. The Strait of Hormuz remains closed to normal commerce. Thousands have already died. And the machinery of escalation, once set in motion, has shown no sign of slowing.
