Beyond Battlefield Victory: What Will Decide the Iran-United States-Israel War

Does Iran Remain a Coherent State?

The first test is whether the US and Israel let an authority accepted by Iranians to retain control over the armed forces, nuclear material, borders, ports, public administration, and negotiations. A stable outcome is unlikely if regime change is pursued under the cover of nuclear or Hormuz concerns. Leadership strikes may violate international law and undermine rational crisis management. They can disrupt operations but also weaken the authority needed to stop fighting and implement an agreement. A weak successor may compromise less, while fragmented security structures could disperse capabilities and make nuclear custodianship more uncertain.

This creates a difficult reality: states oppose Iran's government but there is still need of coherent Iranian institutions. State cohesion is not approval of the regime only; it is necessary for nuclear accounting, border control, administration, and enforceable commitments. Removing a leadership is easier than anticipating a legitimate and capable successor.

Few indicators thus emerge: do Tehran's orders still govern national forces? Are ministries functioning and salaries paid? Is there one recognized negotiating authority? Are nuclear records and personnel under accountable control? Are provincial and minority regions part of a national process or drifting toward competition? These indicators matter more than daily target counts.

Can the World Re-establish Nuclear Knowledge?

The nuclear problem is no longer only how much capacity Iran has, but how much the US and Israel are willing to accept. If Tehran intended to build a weapon, its existing or suspected enriched uranium stocks could already have enabled that despite stringent IAEA safeguards. As an NPT state, Iran has obligations but also rights. Coercing it to surrender those rights may ultimately push it toward greater use of its geographic leverages.

On the other hand, IAEA Director General reported on 8 June 2026 that in-field verification had largely stopped, access to facilities affected by the June 2025 attacks had been unavailable for almost a year, and continuity of knowledge had been lost. The Agency could not verify a previously declared stock that included 440 kilograms of highly enriched uranium (HEU). It did not say the material had been diverted or weaponized, only that its status could not be verified.

This distinction is crucial. Bombing may reduce physical capacity but increase uncertainty about surviving material, equipment, personnel, and intent. The US and Israel may then assume the worst, while Iran may disperse assets to avoid further strikes. Each side's response reinforces the other's fears.

Restoring what was not broken in the first place and knowledge of Iran's nuclear program requires a new baseline: declarations of material, components, damaged sites, debris, relocations, and reconstruction since continuity was lost. Inspectors will need access, sampling, records, interviews, and managed access to sensitive locations. The aim is to rebuild a common factual record, so disputes do not become intelligence contests.

The legal bargain also needs clarity. The NPT bars Iran from acquiring nuclear weapons and requires safeguards, while recognizing its right to peaceful nuclear use. Iran argues this includes safeguarded domestic enrichment, though that claim is contested. A durable agreement must therefore define permitted activities, stockpiles, monitoring, and consequences without denying Iran's rights or treating them as unlimited.

The US, Israel, and Iran have different legal positions. The US is an NPT nuclear-weapon state and remains bound by the treaty's disarmament obligations. It is also bound not to attack or coerce a non-nuclear-weapon state party to the NPT. Israel never joined the NPT and has not accepted its prohibition on acquisition or comprehensive safeguards rules. Iran joined as a non-nuclear-weapon state, is legally bound not to acquire a bomb. It has followed that obligation and demands its right of peaceful use of nuclear energy and an assurance that it will not be attacked or coerced either by the nuclear-armed parties to NPT or their allies. This explains the difference in treaty obligations; it does not make the order equal. Israel's non-party status is not an NPT-granted right to possess nuclear weapons, and nuclear opacity does not confer immunity or a license to use preemptive force.

Thus, the core issue goes beyond law. If NPT membership brings restraint and inspection but no credible protection from attack by nuclear-armed states, abstinence becomes harder to defend inside Iran. An unequal order can still limit proliferation only if restraint brings real security. That is why exceptionalism, nuclear accounting and protection against renewed attack must be negotiated together.

Does Degradation Outlast Reconstitution?

Destroyed capability is a wasting asset. Its strategic value declines as soon as rebuilding begins. The US and Israel report substantial damage to Iran's missile, naval, command, and nuclear infrastructure. Those reports matter, but belligerent assessments are not a complete measure of durable effect. The relevant comparison is between the rate of degradation and the rate of reconstitution. Iran can replace fixed sites with dispersal, large systems with smaller ones, direct operations with partners, visible production with concealment, and vulnerable communications with delegated authority.

Military action produces lasting gains only if the post-war order slows these adaptations. This requires monitoring, export controls, limits on selected production and deployment, and incentives for Iran to remain inside the arrangement. Otherwise, repeated preventive strikes become the strategy. Each round may buy time, but it also encourages hardening, concealment, larger inventories, and shorter decision times.

The same logic applies to Iran's pressure tactics: pressure on shipping can impose global costs but invite stronger maritime coalitions, sanctions, and attacks on Iranian naval capability. Support to armed partners can create strategic depth but weaken Tehran's claim that neighboring states must remain outside the conflict. Instruments that produce leverage in one phase can narrow diplomatic options in the next.

Can Each Government Deliver What It Promises?

The central obstacle is the fear that no party can bind the actors whose conduct matters. Iran will question whether Washington can prevent another Israeli strike; Israel whether Tehran can restrain affiliated groups and covert rebuilding; Gulf states whether US bases make them targets; and Washington whether Iranian negotiators can bind autonomous security organizations.

A useful agreement must therefore clearly assign responsibility. It should distinguish direct orders, material support, negligence, and genuinely autonomous action, and define what evidence triggers consultation, temporary countermeasures, or a material breach. Vague promises to "exercise influence" will not survive the first serious incident, like a missile, assassination, cyberattack, or disputed inspection.

Coalition differences add another layer. Washington and Israel agree on preventing an Iranian weapon but may differ on acceptable uncertainty and the duration of restraint. Gulf states seek protection without permanent entrapment in either camp. China, Russia, Türkiye, Qatar, Pakistan, and European states support different parts of a settlement and possess different forms of leverage. These differences can create bargaining space. They can also produce parallel commitments that no single actor can enforce.

Can Coercion Be Exchanged for Compliance?

An agreement will fail if verified steps bring no visible benefit. US sanctions, financial restrictions, maritime pressure, and blockade measures aim to reduce Iran's revenue and raise the cost of resistance. Iran uses navigation, oil flows, regional reach, and nuclear uncertainty as counter-leverage. Hormuz is therefore part of the bargaining structure, with disruption imposing wider energy, shipping, insurance, and fiscal costs well beyond the belligerents. The IMF and World Bank have warned of the disproportionate impact on importing and lower-income states, including Pakistan.

Is pressure reversible? If Iran provides access but receives only symbolic relief, future compliance becomes harder to defend in Tehran. If sanctions and maritime restrictions are lifted before inspectors establish a baseline, Washington and Israel will fear that relief is financing reconstruction. Sequencing must therefore be reciprocal, visible, and reversible.

This is where economic measures matter strategically. Not because "economic effects" form a separate theoretical category, but because they are the currency of implementation. An inspection visit completed, a tranche of assets released, a ship allowed to pass, or a sanction suspended is evidence that the bargain works. Without such exchanges, declarations of principle will not survive political opposition on either side.

Guarded Accommodation

This is the most stable outcome still available. It requires no trust, friendship, or ideological reconciliation. Iran accepts defined nuclear limits and selected restraints; the US provides phased sanctions and maritime relief; Israel accepts a nonattack arrangement while verified conditions are met; and regional states support monitoring and deconfliction.

Each side can frame the outcome in its own language. Iran preserves sovereignty and nuclear rights; Washington gains verified threat reduction; Israel gains longer-term prevention. The narratives need not agree, but the obligations must.

Signs of progress would include sustained IAEA access, an agreed inventory baseline, limited asset releases, restored shipping, lower military alerts, and hotline use after incidents. Main risks are disputed inspections, attacks by affiliated groups, Israeli strikes outside the process, or failure to deliver promised economic relief.

Armed Intermission

This is the most likely failure mode. Major fighting stops, but the conflict remains unresolved. Iran rebuilds and disperses; Israel keeps unilateral freedom of action; the US maintains sanctions and maritime pressure; and inspections remain partial. All sides call the pause a victory and prepare for the next round.

An armed intermission may last months or years, but duration is not stability. Warning signs include temporary deals without a consolidated text, disagreement over covered actors, limited inspection access, renewed sanctions-evasion networks, recurring shipping incidents, and rhetoric that treats every violation as the end of diplomacy.

Managed Transition / Leadership Change

A managed transition is possible if a recognized authority retains state control, command chains, and sensitive capabilities. The US and Israel would prefer a friendly government, continuity of institutions and unified nuclear and missile control.

However, the bar is high. Any successor seen as imposed by foreign force may lack popular support, face nationalist resistance, and even reject US-Israeli terms more strongly than its predecessor. Outside powers should distinguish support for Iranian political choice from selecting Iran's political order. The decisive indicators are whether security forces enter a common command, whether administration continues, and whether the IAEA gains prompt access.

Cascading Disorder

This is the outcome every regional state should prevent. Central authority fragments; armed groups compete; nuclear material, records, and personnel become uncertain; peripheral regions are contested; and outside powers intervene through local partners. Maritime coercion becomes decentralized and displacement accelerates.

No party wins. The US and Israel face more numerous and less accountable threats; Iran loses effective sovereignty; Gulf states absorb attacks and economic disruption; and Pakistan faces border insecurity, refugee pressure, sectarian risk, and higher energy costs. Warning signs include rival national commands, unpaid or autonomous forces, missing nuclear custodians, conflicting shipping orders, seizure of energy infrastructure, and externally sponsored territorial factions.
