After seven weeks of war, the United States and Iran have finally reached a ceasefire framework. The agreement follows the failed Islamabad negotiations last weekend and several days of intense mediation involving Pakistan, Oman, Qatar and other regional governments, alongside American pressure through the threatened naval blockade of Iranian ports. Under the emerging arrangement, Iran has agreed to restore unrestricted commercial passage through the Strait of Hormuz, while Washington has suspended implementation of the blockade and both sides have halted major offensive military operations as negotiations move towards a broader settlement covering Iran’s nuclear programme, sanctions and regional security. Israel is not formally a party to every component of the US-Iran agreement, making implementation more complicated, while several technical questions remain unresolved. The ceasefire is therefore fragile and should not be confused with peace. Yet after a conflict that killed senior Iranian leaders, disrupted global energy markets and brought American forces into direct sustained combat with Iran, reaching even this point is significant. The most important lesson from the war may ultimately be surprisingly modest: military power changed the bargaining position of both states, but neither possessed enough power to create a political order the other could simply be forced to accept indefinitely.
That distinction matters because the war began with an assumption common to asymmetric conflicts: if one state possesses overwhelming military superiority, sufficient pressure should eventually make the weaker state concede. The United States and Israel demonstrated extraordinary ability to penetrate Iranian airspace, destroy infrastructure and eliminate senior leadership. Iran never acquired anything approaching comparable conventional capability. Yet Tehran retained missiles, drones, geography and enough control over Hormuz to impose significant economic costs internationally. The result was an unusual form of mutual vulnerability without military equality. America could damage Iran far more severely than Iran could damage America, but Iran could still affect things Washington valued enough to prevent military superiority from becoming complete political control.
This is a useful correction to an overly material understanding of power. Counting aircraft, GDP and defence budgets tells us something important about which state can win military engagements. It does not tell us automatically which state can obtain its preferred political outcome. Political power depends on preferences as well as capabilities. If Iran values preserving sovereignty and deterrence more intensely than America values extracting another concession, Tehran can rationally tolerate much larger material costs. Conversely, American voters and allies may become increasingly unwilling to bear rising oil prices and regional instability for marginal additional gains. Bargaining outcomes therefore depend partly on who cares more about the final unresolved concession, not simply who possesses more weapons.
The ceasefire appears possible because both governments have now moved away from their most expansive positions. Iran cannot plausibly maintain a system in which it effectively taxes or politically controls passage through Hormuz without provoking continued international opposition. Freedom of navigation through such an economically important waterway is too valuable to too many countries. Washington, meanwhile, appears to have stepped back from making immediate transformation of Iran’s political system a necessary condition for ending military operations. That is strategically important. Preventing nuclear proliferation and maintaining open shipping are objectives that can be verified through observable behaviour. Determining whether another country’s political regime has become sufficiently acceptable is much more subjective and potentially limitless.
This is why bounded objectives make wars easier to terminate. If success means Iran allows inspections, limits enrichment and keeps Hormuz open, negotiators can construct indicators showing whether compliance exists. If success means Iran becomes moderate, democratic and permanently friendly towards Israel and America, there is no obvious point at which military action has achieved the objective. The more a war attempts to transform intentions rather than constrain behaviour, the harder it becomes to know when enough force has been used.
Iran’s leadership faces an equivalent philosophical adjustment. Sovereignty cannot mean possessing an unrestricted right to create severe external risks for other states. Tehran can legitimately insist that Iran remain politically independent and retain ordinary defensive capabilities. It cannot reasonably demand that other countries accept unlimited nuclear latency, attacks by aligned armed organisations or arbitrary interference with international shipping merely because those instruments compensate for Iranian conventional weakness. Political independence gives states authority over themselves; it does not give them authority over the security of everyone around them.
The nuclear negotiations will therefore determine whether the ceasefire becomes durable. The strongest arrangement would not attempt to eliminate nuclear knowledge from Iran, which is impossible, but would make weaponisation difficult to conceal and sufficiently costly that remaining below the threshold becomes rational. That requires intrusive verification combined with incentives for compliance. Iran needs to know that sanctions actually decline if it follows the agreement. America and Israel need confidence that violations are detected quickly and produce predetermined consequences. Deterrence works better when both punishment and reward are credible.
This is where the experience of the 2015 JCPOA should matter. One weakness of that agreement was not simply its technical provisions but its political durability. Trump withdrew America in 2018, Iran subsequently expanded its nuclear activity and each side concluded the other could not be trusted to maintain commitments. Any new arrangement resting almost entirely on presidential discretion risks reproducing the same cycle after the next election. Congressional involvement, international guarantees and clear multilateral verification would therefore make the agreement more credible. Institutions matter because leaders eventually leave office while the incentives created by their agreements need to survive them.
The Strait of Hormuz should generate a parallel institutional arrangement. Iran’s geography cannot be changed, and Gulf energy dependence will remain substantial even as countries diversify. The objective should therefore be reducing the extent to which every future US-Iran confrontation immediately threatens global shipping. Monitoring mechanisms, naval communication channels and explicit navigation rules could create some separation between bilateral conflict and international commerce. The principle is straightforward: states should not be able to convert geographic accidents into unlimited political authority over global public goods.
For India, the ceasefire is an immediate economic relief but also another warning. Energy prices can fall and shipping can normalise, yet the structural vulnerability remains. India still imports most of its crude oil and remains exposed to Gulf instability. The rational response is not abandoning the Gulf but increasing resilience through diversified suppliers, strategic reserves, renewable and nuclear capacity, electrified transport and more efficient energy use. Strategic autonomy becomes stronger when diplomacy and material capacity reinforce one another.
The diplomatic role played by Pakistan, Oman and Qatar is equally worth noticing. None possesses American military power, yet each had something Washington and Tehran needed: channels, trust and enough distance from the conflict to transmit proposals. This demonstrates another form of international power that receives less attention than military capability. A state can become influential by being useful to actors that cannot communicate effectively with one another. In an increasingly multipolar system, diplomatic connectivity can give middle powers leverage disproportionate to their economic size.
The greatest uncertainty now concerns Israel. Israel entered the conflict because it viewed Iranian nuclear and missile capabilities as existential threats, and it may demand stronger restrictions than Washington ultimately considers necessary for ending the war. That creates a familiar alliance problem: American and Israeli objectives overlap substantially without being identical. Washington bears global economic and military costs Israel does not experience in the same proportions, while Israel experiences direct Iranian security threats more intensely than America. Neither country’s preferred risk tolerance therefore automatically determines what is rational for the other. Alliances coordinate interests; they do not erase differences between them.
The war has also left Iran politically transformed. Ali Khamenei is dead, Mojtaba Khamenei has succeeded him and the Islamic Republic has survived a direct attempt to weaken its leadership. Whether that strengthens or ultimately destabilises the regime remains uncertain. The appearance of hereditary succession creates a serious ideological contradiction for a republic founded against monarchy, while wartime mobilisation may strengthen the security establishment temporarily. Outside governments should resist assuming either collapse or consolidation is inevitable. Political systems can remain coercively strong while their legitimacy erodes gradually underneath them.
That uncertainty is another reason the ceasefire should not depend on regime change. Iran’s political future ultimately belongs to Iranians. The international security problem is narrower: ensuring whatever government rules Iran cannot develop nuclear weapons secretly or impose unacceptable costs on neighbouring states and global commerce. Keeping those questions separate makes both easier to address.
Seven weeks of war have therefore produced something less dramatic than victory but potentially more useful: a recognition of mutual limits. Iran has learned that its military infrastructure and leadership are extraordinarily vulnerable to American and Israeli power. America has learned that destroying Iranian targets does not automatically produce Iranian political submission and that a weaker adversary positioned beside critical global infrastructure can impose substantial indirect costs.
If the ceasefire survives, each side will inevitably claim that its own pressure forced the other towards negotiation. Both claims can contain some truth. That is not a problem. Peace agreements often become politically durable precisely because governments can describe them differently to their own populations.
The important question is what behaviour follows, not whose narrative wins. If Hormuz remains open, nuclear inspections return, sanctions decline conditionally and major attacks stop, then the ceasefire will begin creating interests in its own survival. Businesses will resume shipping, households will benefit from lower energy prices and governments will acquire something they risk losing through renewed war. The strongest peace is eventually protected not by trust between former enemies but by the accumulation of ordinary things that both sides would rather not destroy again.
That process has only begun. The war has stopped for now. Whether peace follows will depend on whether America and Iran can turn the limits they discovered through violence into rules neither needs another war to rediscover.
