Six months have passed since the US and Israel launched their latest war against Iran in February 2026. What was expected to be a short, overwhelming campaign has instead developed into another open-ended American war in the Middle East.
On the 6th month anniversary, President Trump instructed top administration envoys to halt their conversations with Iran and communicate to political allies that they are shifting their strategy, going from “hammer Iran ASAP” to “strangle them” over time.
Washington has inflicted enormous damage on Iran, assassinated senior figures and deployed overwhelming air power. But none of this has produced the decisive political outcome that matters: Iran has not capitulated. The problem facing Washington is therefore no longer simply how to defeat Iran militarily. It is how to end a war whose original strategy has failed without making the US look defeated. And there are increasingly few good options.
The Failed Decapitation Strategy
The original US-Israeli strategy rested on an assumption that has repeatedly shaped Western wars: destroy the leadership, communications and military infrastructure of an adversary and the collapse of the political system will follow.
The opening phase focused heavily on air strikes and assassinations. Senior Iranian leaders and commanders were targeted in an attempt to decapitate the regime. Washington calculated that once Iran’s senior leadership was removed and its military infrastructure damaged, those remaining would conclude that further resistance was pointless and negotiate from a position of weakness.
Instead, Iran absorbed the attacks and continued fighting. The US consequently discovered the difference between destroying targets and achieving political objectives. Air power can destroy buildings, command centres, radar installations and military equipment. It cannot automatically force a state to surrender. This is especially true when that state has spent decades preparing for precisely such a confrontation.

Iran Prepared for This War
Iran never attempted to compete symmetrically with the US. It could not build an air force capable of matching American stealth aircraft or create a conventional military capable of defeating the US in a traditional battlefield confrontation.
Instead, Tehran invested heavily in the capabilities where geography, technology and economics could reduce America’s advantages. Missiles and drones became central to this strategy. Rather than concentrating solely on attacking American combat forces, Iran targeted the infrastructure that makes modern American warfare possible: bases, radar, surveillance systems, communications facilities and other elements of America’s regional military architecture.
America’s enormous technological superiority depends upon these eyes and ears.
Once they are degraded, American aircraft, missile defences and military units become less effective. Iran also spent decades developing underground missile facilities, production sites and hardened infrastructure. What appeared excessive during peacetime became invaluable once sustained air attacks began.

The contrast with America’s regional posture became increasingly significant. Iran dispersed and buried much of its critical military infrastructure. America concentrated expensive equipment and personnel in identifiable bases throughout the region. The stronger military therefore possessed some surprisingly vulnerable pressure points.
Iran’s Real Nuclear Weapon
But Iran’s greatest advantage was never a missile or drone. It was geography. The Strait of Hormuz is one of the most strategically important pieces of territory on earth. A substantial proportion of globally traded oil and liquefied natural gas passes through this narrow maritime corridor. Iran’s closure of the Straight has fundamentally altered the economics of the war.
Washington could attack Iran, but Tehran could impose costs far beyond the battlefield.
Disruption to energy supplies increased pressure on global markets while threatening America’s regional partners and the wider international economy. The longer the conflict continued, the greater these economic costs became.
This created an unusual form of escalation dominance. America possessed vastly greater conventional military power, but using more of that power did not necessarily improve Washington’s strategic position. Greater escalation risked greater Iranian retaliation against regional infrastructure and further disruption to Hormuz. America could therefore win individual military exchanges while simultaneously worsening the strategic problem it was attempting to solve.
What Was the War Actually For?
Six months later, the original justification for America’s involvement look increasingly confused. Comments from Secretary of State Marco Rubio have reinforced the conclusion that America’s entry into the conflict was fundamentally connected to Israel and the consequences Washington believed Israel would face without direct American involvement. That matters because many of the wider arguments used to justify the war have become harder to sustain.
America was not facing an Iranian invasion. Iran did not represent a conventional military threat to the American homeland. Washington nevertheless entered another major Middle Eastern conflict with no obvious mechanism for translating military superiority into a sustainable political settlement. The result is a familiar American problem.
Vietnam, Iraq and Afghanistan were enormously different conflicts, but each demonstrated the limitations of overwhelming military superiority when the political objective cannot easily be achieved through force. Iran is now exposing the same contradiction.
Negotiations Reveal a New Regional Balance
The move towards direct negotiations is therefore significant. Washington initially expected military pressure to force Iran to negotiate from weakness. Instead, negotiations have become increasingly necessary because military pressure has failed to produce capitulation.
That changes the bargaining position. Iran knows Washington wants an exit. Tehran therefore has little incentive to offer major concessions simply because America demands them.
This is where six months of warfare has left the Trump administration. It needs something it can describe as victory. Iran knows it and this leaves Washington with four broad options:-
Option One: Escalate – The first is straightforward: massively increase military pressure. Washington could launch a new wave of strikes, expand the target list and attempt to destroy enough Iranian military and economic infrastructure that Tehran eventually concludes continued resistance is futile. Israel would almost certainly favour such an approach.
The problem is that escalation is essentially an intensified version of the strategy America has already pursued. If six months of air attacks and assassinations have not produced capitulation, why would another round of attacks be any different.
This option will almost certainly cause significantly higher American casualties. Destroying a large, mountainous country of nearly 100 million people is very different from forcing its government to surrender. At its extreme, genuinely decisive escalation could ultimately require ground forces. That would turn America’s difficult war into a potentially catastrophic one.
Option Two: Negotiate and Fight Another Day – The second option is to negotiate seriously. This would mean accepting that Iran will demand concessions in return for ending the conflict and reopening the regional energy system.
Strategically, this may be America’s least damaging option. Washington could preserve its forces, rebuild depleted stocks, repair its regional military infrastructure and reassess its Iran strategy later. But politically it would be difficult.
After six months of presenting Iran as an adversary that must be defeated, concessions would inevitably be interpreted as evidence that Tehran successfully resisted American pressure. It could also create significant tensions with Israel, particularly if Israel believes Washington is ending the conflict before Iran’s capabilities have been destroyed.
The advantage, however, is simple: America gets out. Great powers sometimes retreat from unfavourable confrontations precisely so they can preserve power for future ones. Just ask Russia.
Option Three: Outsource the Pressure – Washington’s third approach appears to involve regional diplomacy. The US has sought to use indirect negotiations and increasingly important relationships involving Saudi Arabia, Pakistan and Turkey to place additional pressure on Tehran.
If Washington cannot compel Iran directly, countries with important economic, political or security relationships with Tehran can persuade it to compromise. But intermediaries only possess leverage when both sides need something. Iran currently believes time is working in its favour. If Tehran considers itself to be negotiating from strength, regional diplomatic pressure alone is unlikely to convince it to surrender concessions that American military power could not extract.
Regional diplomacy may help construct an eventual settlement. It is much less likely to manufacture an American victory.
Option Four: The Unthinkable Escalation – The final possibility would be an extreme attempt to fundamentally change Iran’s calculations — potentially including nuclear escalation.
Such an option would be dangerous and strategically self-defeating. A nuclear weapon does not respect political boundaries. Fallout, escalation and panic would affect a region containing some of the world’s most important energy resources.
Any nuclear use would also transform the international consequences of the war. Oil and gas prices would surge, shipping would collapse across the Gulf and financial markets would experience a shock far beyond anything produced by the conflict so far.
Conclusions: Another Forever War?
This is ultimately the dilemma facing Donald Trump. America entered a war that Washington expected its overwhelming military superiority to settle relatively quickly. Six months later, Iran remains standing, American resources have been depleted, and negotiations have become more important rather than less.
Trump now needs an exit that looks like victory. Iran has every reason to deny him one cheaply. This does not mean America has been militarily defeated in the conventional sense. The US remains vastly more powerful than Iran and retains enormous capacity to inflict destruction.
But wars are not ultimately measured by how many targets are destroyed. They are measured by whether political objectives are achieved. Six months into the Iran war, Washington has still not achieved the objective that mattered most: forcing Tehran to capitulate.
America can escalate and accept potentially enormous costs. It can negotiate and accept concessions. It can continue searching for regional pressure that changes Iran’s calculations. Or it can contemplate increasingly dangerous forms of escalation. None represents the decisive victory Washington expected.
Like empires throughout history, America has discovered that starting wars is considerably easier than ending them. A conflict that was supposed to demonstrate overwhelming American power has instead become another forever war.
