A. Negotiated Ceasefire (6 scenarios)
From quick deal to frozen conflict.
A1
Quick Omani-Mediated Deal
5/10
2-6 wks
Oman brokers ceasefire. Iran halts retaliation for strike cessation + partial sanctions relief.
Parallel: Iran hostage crisis — Algerian mediation
72-hour pause → 30-day ceasefire → permanent terms. IAEA inspections; sanctions paused.
A3
Humanitarian Corridor → Ceasefire
4/10
Aid corridors become de facto ceasefire zones that gradually expand.
Chapter VII resolution. Risk: US veto.
A5
Trump-IRGC Back-Channel Deal
4/10
Direct deal: IRGC survival guarantees + sanctions relief for nuclear restrictions. Parallel: Trump-Kim summit.
A6 ★ LIKELY
Frozen Conflict
7/10
No deal. Strikes reduce. Both claim victory. Low-level hostilities indefinitely. Parallel: Korean War armistice.
B. Regime Change (6 scenarios)
From IRGC coup to state fragmentation.
IRGC removes Mojtaba, establishes military government, negotiates with US.
Civilian uprising during war chaos. Building on Dec 2025 protests (all 31 provinces).
Leadership accepts exile to Russia/China. Transitional government.
IRGC suspends theocracy, opens economic reforms and nuclear talks.
Central govt collapses. Kurdish, Baloch, Azeri regions assert autonomy. Failed state.
B6 ★
Theocratic Continuity
6/10
Regime survives battered under Mojtaba + IRGC. Programs rebuilt. Future crisis guaranteed.
C. Military Escalation (7 scenarios)
Paths to a wider, more dangerous war.
Mines, subs, anti-ship missiles. 20% of global oil halted. Oil $200+. Global recession.
Race to assemble crude nuclear device from remaining enriched uranium.
C3
Major US Casualty Event
5/10
Attack kills hundreds of US personnel. Pushes to ground invasion OR withdrawal (Beirut model).
C4
Cyber Infrastructure Attack
4/10
Iran targets US/allied power grids, financial systems. Asymmetric, deniable.
Attack on US soil via operatives/Hezbollah cells. Guarantees regime destruction.
Iraq + Lebanon become active theaters. US overstretched in three wars.
Desperate regime deploys CW. International red line. Guarantees intervention.
D. Economic Resolution (6 scenarios)
Where money ends the war.
D1 ★
Oil Shock Forces Mediation
6/10
Oil $180-200. G7/G20 emergency summit. Pressure on US + incentives for Iran.
JCPOA 2.0. Too ambitious for current trust levels.
D3
Iran Collapse → Capitulation
4/10
68% inflation pushes past breaking point. Not peace — surrender.
D4
China Economic Intervention
3/10
China offers Iran lifeline conditional on ceasefire.
Saudi-led effort for oil market stability.
Refugee crisis + casualties force sanctions modification.
E. Proxy & Regional (6 scenarios)
Proxies and neighbors widen the war.
E1 ★
Hezbollah Full Activation
6/10
Full-scale rockets on Israeli cities. Israel ground op into Lebanon.
E2
Houthi Red Sea Escalation
5/10
Full 2023-24 style shipping attacks. Global trade disrupted.
E3 ★
Iraqi Militia Insurgency
6/10
Sustained campaign vs US in Iraq. 67 strikes claimed in first 3 days.
Iran targets Saudi/UAE oil infrastructure. Gulf states enter war.
E5
Turkey/Pakistan Drawn In
2/10
NATO and nuclear complications.
E6
Israel Ground Operation
2/10
Ground forces in Iran. No exit strategy.
F. Great Power Intervention (6 scenarios)
Outside powers change the calculus.
F1 ★
China Diplomatic Initiative
5/10
China leverages Iran pact + Gulf trade to broker ceasefire. Oil supply is the motivator.
F2
Russia Military Support
2/10
S-400s, satellite intel. Risk of US-Russia confrontation.
European peacekeeping plan through UN.
India positions as honest broker.
Shanghai Cooperation Org collective mechanism.
F6
Trilateral Pact Activation
2/10
China-Russia-Iran military coordination. New Cold War.
G. Stalemate & Attrition (6 scenarios)
Nobody wins, nobody quits.
G1 ★ HIGHEST PROBABILITY
Prolonged Air Campaign
7/10
2-6 mo
US air/missile strikes continue. No ground troops. Iran retaliates with diminishing capability. No decisive outcome.
Parallel: NATO bombing of Serbia (1999) — 78 days, no ground troops. Air alone rarely achieves regime change.
G2 ★
Low-Intensity Tit-for-Tat
6/10
Periodic strikes. Neither side acknowledges ceasefire. The new normal.
Periodic degradation strikes against Iranian rebuilding.
Both sides tire. No agreement, just gradual cessation. Technically still at war.
Iran shifts to cyber/proxy/terrorism. US struggles with dispersed threats.
Iran disrupts oil; US total blockade. Who breaks first?
H. Wild Cards (6 scenarios)
Low-probability events that change everything.
Constitutional/economic crisis forces de-prioritization.
Iranian intel targets major Western leader. Unlimited escalation.
Iran/allies disrupt global financial systems or power grids.
Major earthquake on Iran's seismic zone disrupts operations.
Strikes on nuclear facilities cause radiological release.
Congressional War Powers + Pentagon pushback halts campaign.
Most Likely Outcome
Weighted composite of highest-probability scenarios.
Bottom Line
War ends within 3-5 months via mutual exhaustion + Omani/Chinese mediation + face-saving phased ceasefire. Neither side achieves objectives. Regime survives weakened. No formal peace — frozen conflict like Korea. Future crisis in 5-10 years.
Projected Timeline
| Phase | When | What | Prob |
|---|
| 1. Peak | Apr | Proxies escalate, oil $180+, air campaign | ~70% |
| 2. Pressure | Apr-May | Oil shock, Iran collapse, ceasefire calls | ~60% |
| 3. Talks | May-Jun | Oman mediates, China active, Trump seeks deal | ~50% |
| 4. Resolution | Jun-Aug | Phased ceasefire → frozen conflict | ~35% |
Key variable: Trump's patience. If "weeks not months" is real → deal by June. If rhetoric → attrition through summer.
Outcome Probabilities
| Outcome | Probability |
|---|
| Ends within 6 months | ~60% |
| Active combat past Oct 2026 | ~40% |
| Phased ceasefire → frozen | ~35% |
| Regime change in Iran | ~15% |
| Formal peace treaty | <5% |
