Conflict Timeline & Projected Resolution

February 28, 2026

War Launch: US-Israeli war with Iran begins with intensive combined airstrikes targeting Iran's ballistic missile industrial base, air defenses, command-and-control infrastructure, and internal security forces.

March 2-9, 2026

Accelerated Campaign: ISW reports document rapid degradation: 75% of missile launchers destroyed, 90% reduction in ballistic missile attacks, 83% reduction in drone attacks, air superiority achieved, over 3,000 targets struck, and systematic dismantling of missile production infrastructure.

Mid-to-Late May 2026

Primary Phase Conclusion: Intensive combined airstrikes and Iranian/Axis retaliation expected to conclude. Missile program effectively neutralized, retaliation becomes negligible, internal security degradation triggers widespread unrest or elite defection.

Early-to-Mid June 2026

Full Resolution: Complete resolution via Iranian military collapse, internal regime implosion under succession pressures, or forced ceasefire/negotiated settlement. US/Israel declare objectives met. Sporadic proxy actions may linger but major combat ends.

Key Factors Supporting This Prediction

1. Severe Military Capability Degradation

The combined US-Israeli force has achieved overwhelming military superiority and systematically destroyed Iran's key capabilities. ISW reports document that by March 8, approximately 75% of Iran's missile launchers have been destroyed, with IDF estimates showing only ~120 remaining by March 7.

Missile Launcher Destruction

75%

Ballistic Missile Attack Reduction

90%

Drone Attack Reduction

83%

Over 3,000 targets struck by March 6 (CENTCOM confirmed)
Air superiority achieved and confirmed by CENTCOM (March 5)
IDF attacked over 400 missile-related targets in 24 hours (March 8)
Systematic strikes on Shahroud, Parchin, Khojir, Shiraz, Chamran, Garmdareh, and Khorgu bases
Planetary mixers and underground facilities destroyed that Iran cannot quickly replace

2. Critical Infrastructure Destruction

The campaign has expanded beyond military targets to include critical infrastructure that sustains Iran's war effort and regime stability. Oil infrastructure strikes (Tondgouyan and Shahran refineries plus storage in Tehran and Karaj) began March 7, exacerbating pre-existing energy blackouts and directly undermining military sustainment.

Oil refineries struck: Tondgouyan and Shahran (March 7)
Storage facilities targeted in Tehran and Karaj
Pre-existing energy blackouts exacerbated
Military sustainment directly undermined
Naval and airbase strikes (Esfahan airbases, Bushehr, Bandar Abbas) have cratered runways and destroyed aircraft
Iranian power projection capabilities severely limited

3. Internal Security Force Degradation

Most critically for regime stability, ISW tracks a deliberate shift to internal security targets since early March. Repeated strikes on Law Enforcement Command (LEC) headquarters/stations, Basij bases, IRGC Ground Forces divisions, and morality police facilities have degraded the regime's ability to suppress protests and maintain control.

LEC headquarters/stations struck in Esfahan City/Province, Borujerd, Kuhdasht, Eslamabad-e Gharb, Abdanan
Basij bases targeted in Najafabad, Shahreza, southeastern Tehran
IRGC Ground Forces divisions hit: 14th Imam Hossein, 8th Najaf-e Ashraf Armored, Saheb ol Zaman Provincial Unit in Esfahan (March 8-9)
Morality police facilities targeted
Degradation in provinces with recent unrest (Esfahan, Lorestan, Kermanshah) directly erodes regime control
These units historically suppress protests; their degradation enables widespread unrest

4. Leadership Chaos and Regime Instability

Ali Khamenei's death (February 28) led to a temporary Leadership Council, and on March 8 the Assembly of Experts selected hardliner Mojtaba Khamenei as Supreme Leader. However, ISW assesses this faces immediate legitimacy crises, clerical opposition, accusations of hereditary monarchy, and factional fractures.

Ali Khamenei's death created leadership vacuum (February 28)
Mojtaba Khamenei selected as Supreme Leader (March 8)
Faces legitimacy crises and clerical opposition
Accusations of hereditary monarchy undermine legitimacy
Factional fractures: hardliners criticizing President Pezeshkian's "weak" statements (March 7)
Ongoing decapitation: new Supreme Leader Office Military Chief Babaeiyan killed (March 7)
Mojtaba's selection does not restore command cohesion

5. Declining and Ineffective Iranian Retaliation

Iranian retaliation, while persistent, has become increasingly ineffective and dispersed. Daily missile waves to Israel (6-10 per day, March 6-9) show minimal impacts until March 9 cluster munitions killed one civilian and wounded three in central Israel. Attacks on Gulf states show volume reductions and no strategic effect.

6-10 daily missile waves to Israel (March 6-9) with minimal impacts
March 9 cluster munitions: one civilian killed, three wounded (first significant impact)
Gulf state attacks: 15 ballistic + 18 drones to UAE (March 9), desalination plant in Bahrain, refinery fire injuring 32
Debris in Turkish airspace, civilian deaths in Saudi Arabia
Volume reductions and no strategic effect
Axis proxies remain active but severely degraded: IDF counterstrikes (600+ targets, 200+ fighters killed since Feb 28)
Hezbollah claimed ground engagements but IDF counterstrikes have severely degraded capabilities

6. US-Israeli Sustainment Indicators

US-Israeli sustainment indicators further support a short timeline. CENTCOM has requested additional intelligence officers only until mid-June (potentially September), signaling planning for a finite campaign rather than indefinite war. Discussions of special forces for HEU extraction are framed as post-major-threat.

CENTCOM requested additional intelligence officers only until mid-June (potentially September)
Signals planning for finite campaign, not indefinite war
Special forces discussions for HEU extraction framed as post-major-threat
Additional carrier strike groups preparing but not yet required
No ISW report indicates Iranian reconstitution capability sufficient to prolong beyond weeks
No indication of proxy resurgence sufficient to prolong conflict

7. Projected Timeline from Current Acceleration

Projecting forward from the last week's acceleration (daily confirmation of new missile/production/internal strikes, Iranian responses down 90%, new Supreme Leader already under pressure), the missile program will be effectively neutralized within 3-5 more weeks (mid-to-late April), at which point retaliation becomes negligible and internal security degradation will trigger widespread unrest or elite defection.

Missile program neutralized within 3-5 weeks (mid-to-late April)
Retaliation becomes negligible at that point
Internal security degradation triggers widespread unrest or elite defection
Regime collapse or capitulation follows rapidly once air dominance enables uncontested pressure
Historically aligns with ISW's observed patterns in similar decapitation campaigns
Sporadic proxy actions or Gulf incidents may linger into June, but major combat ends when US/Israel declare objectives met
Negotiated pause (possibly US-brokered) could accelerate to early May if Mojtaba seeks survival

Final Prediction

The US-Israeli war with Iran, launched on February 28, 2026, will see its primary phase of intensive combined airstrikes and Iranian/Axis retaliation conclude by mid-to-late May 2026 (roughly 6–8 weeks from the current date of March 9), with a full resolution—via Iranian military collapse, internal regime implosion under succession pressures, or a forced ceasefire/negotiated settlement—most likely by early-to-mid June 2026.

This timeline derives directly from the cumulative operational trends, capability degradations, and leadership fractures documented across all ISW Iran Update Morning and Evening Special Reports for the last week (March 2–9, 2026). The campaign has achieved air superiority, destroyed 75% of missile launchers, reduced ballistic missile attacks by 90%, and systematically degraded internal security forces. Iranian retaliation has become increasingly ineffective, leadership chaos compounds military failures, and US-Israeli sustainment indicators point to a finite campaign timeline.

Recommendation: The conflict will resolve by mid-May to mid-June 2026, with primary phase ending mid-to-late May and full resolution by early-to-mid June.

Frequently asked questions

What is the current status of the Iran-Israel conflict? +

As of March 9, 2026, the US-Israeli combined force has achieved air superiority, destroyed approximately 75% of Iran's missile launchers, reduced ballistic missile attacks by 90%, and struck over 3,000 targets. The campaign has expanded to include critical infrastructure (oil refineries, storage facilities) and internal security forces (LEC, Basij, IRGC Ground Forces). Iranian retaliation has become increasingly ineffective, with 6-10 daily missile waves showing minimal impacts until March 9.

Why is the conflict predicted to end by mid-May to mid-June 2026? +

The prediction is based on several converging factors: (1) Severe military degradation with 75% of missile launchers destroyed and 90% reduction in ballistic attacks, (2) Critical infrastructure destruction undermining military sustainment, (3) Internal security force degradation eroding regime control, (4) Leadership chaos following Ali Khamenei's death and Mojtaba Khamenei's contested succession, (5) Ineffective Iranian retaliation showing declining capabilities, (6) US-Israeli sustainment indicators pointing to finite campaign timeline, and (7) Projected timeline showing missile program neutralization within 3-5 weeks, triggering regime collapse or capitulation.

What is ISW and why are their reports important? +

ISW (Institute for the Study of War) and the Critical Threats Project (CTP) have issued twice-daily Iran Update Morning and Evening Special Reports since the war's outset (February 28, 2026) to track the US-Israeli campaign. These reports document cumulative operational trends, capability degradations, and leadership fractures. ISW's reporting provides detailed, real-time analysis of military operations, infrastructure strikes, internal security degradation, and regime stability indicators that form the basis for this prediction timeline.

What role does regime instability play in the conflict resolution? +

Regime instability is a critical factor. Ali Khamenei's death created a leadership vacuum, and Mojtaba Khamenei's selection as Supreme Leader faces legitimacy crises, clerical opposition, and accusations of hereditary monarchy. Factional fractures are evident, with hardliners criticizing President Pezeshkian. Most importantly, strikes on internal security forces (LEC, Basij, IRGC Ground Forces, morality police) have degraded the regime's ability to suppress protests and maintain control. Once internal security degradation reaches a critical point, widespread unrest or elite defection becomes likely, leading to regime collapse or capitulation.

Could the conflict last longer than predicted? +

While the analysis points strongly to resolution by mid-May to mid-June 2026, several factors could extend the timeline: (1) If Iran demonstrates unexpected reconstitution capabilities, (2) If proxy forces (Hezbollah, etc.) mount more effective resistance than currently observed, (3) If international diplomatic intervention delays resolution, (4) If regime leadership successfully consolidates despite current fractures. However, current indicators show no evidence of Iranian reconstitution capability or proxy resurgence sufficient to prolong beyond weeks. The trajectory points firmly to resolution no later than mid-June 2026.

What does "primary phase conclusion" vs "full resolution" mean? +

"Primary phase conclusion" (mid-to-late May 2026) refers to the end of intensive combined airstrikes and Iranian/Axis retaliation. At this point, the missile program will be effectively neutralized, retaliation becomes negligible, and internal security degradation triggers widespread unrest or elite defection. "Full resolution" (early-to-mid June 2026) refers to complete resolution via Iranian military collapse, internal regime implosion under succession pressures, or forced ceasefire/negotiated settlement. US/Israel declare objectives met. Sporadic proxy actions or Gulf incidents may linger, but major combat ends.

What evidence supports the prediction of regime collapse or capitulation? +

Multiple indicators support regime collapse or capitulation: (1) Internal security force degradation in provinces with recent unrest (Esfahan, Lorestan, Kermanshah) directly erodes regime control, (2) Leadership chaos with contested succession and factional fractures, (3) Critical infrastructure destruction (oil refineries, energy blackouts) undermining economic stability, (4) Military capability degradation making effective resistance impossible, (5) Historical patterns from similar decapitation campaigns showing rapid collapse once air dominance enables uncontested pressure. Once internal security forces can no longer suppress protests, regime collapse becomes likely.
