INDICATORS AND WARNINGS: Scenario Monitoring Framework
Date: 2026-02-12
Purpose: Identify observable indicators that signal which scenario is unfolding
SCENARIO OVERVIEW
| Scenario | Probability | Description |
|---|
| S1: Partial Nuclear Deal | 40% | JCPOA-type agreement with additional constraints; enrichment limits, stockpile caps, enhanced inspections; phased sanctions relief |
| S2: Talks Collapse, Renewed Military Action | 25% | Negotiations fail; military pressure escalates to limited or sustained strikes |
| S3: Comprehensive Deal (Including Missiles) | 15% | Broader agreement addressing nuclear, missiles, and some regional behavior |
| S4: Indefinite Stalemate | 15% | Neither deal nor war; ongoing negotiations without resolution; managed tension |
| Wild Card: Iranian Nuclear Breakout | 5% | Iran uses hidden stockpile to rapidly advance toward weapons capability |
S1: PARTIAL NUCLEAR DEAL (40%)
Indicators That S1 Is Becoming More Likely
| # | Indicator | Observable? | Current Status |
|---|
| S1-1 | Second round of talks takes place within 2 weeks | Yes | Announced but no date set |
| S1-2 | US drops "zero enrichment" language, shifts to "limited enrichment" | Yes | Not yet; monitoring |
| S1-3 | Iran allows IAEA inspectors back to damaged facilities | Yes | Not yet; critical indicator |
| S1-4 | Technical working groups formed on enrichment limits and verification | Partially | Not yet |
| S1-5 | Gulf states publicly endorse emerging framework | Partially | Behind-the-scenes support ongoing |
| S1-6 | Netanyahu shifts from "no deal" to "insufficient deal" rhetoric | Yes | Not yet; currently maximalist |
| S1-7 | US announces partial sanctions relief or asset unfreezing | Yes | Not yet |
| S1-8 | Iran provides information on enriched uranium stockpile location | Partially | Not yet; most critical indicator |
| S1-9 | Trump begins framing a nuclear-only deal as victory | Yes | Not yet; monitoring |
| S1-10 | European (E3) reengagement in the process | Yes | Currently marginalized |
Warning That S1 Is Stalling
- Talks do not resume within 30 days
- Iran or US adds preconditions for further meetings
- IAEA reports new enrichment activity at undisclosed sites
- Netanyahu publicly opposes any deal framework
S2: TALKS COLLAPSE, RENEWED MILITARY ACTION (25%)
Indicators That S2 Is Becoming More Likely
| # | Indicator | Observable? | Current Status |
|---|
| S2-1 | Second carrier group deployed (not just discussed) | Yes | Under consideration only |
| S2-2 | B-2 bombers repositioned to Diego Garcia or forward base | Partially | Not observed |
| S2-3 | Non-essential US personnel evacuated from Gulf bases | Yes | Not observed |
| S2-4 | MOP munitions forward-positioned | Partially | Not observed |
| S2-5 | Iran announces enrichment resumption | Yes | Not yet |
| S2-6 | Iran withdraws from NPT | Yes | Threatened but not acted on |
| S2-7 | IAEA reports evidence of covert nuclear activity | Partially | No current reports |
| S2-8 | Israel conducts unilateral strikes on Iranian targets | Yes | Not observed |
| S2-9 | Trump shifts from "deal" language to "all options" language exclusively | Yes | Currently dual-track |
| S2-10 | Gulf states begin distancing from mediation role | Yes | Not observed |
Critical Trigger Events
- Iran announces enrichment resumption: Would dramatically accelerate S2 timeline
- Evidence of hidden uranium weaponization activity: Would likely trigger immediate US/Israeli response
- Strait of Hormuz incident: Could escalate rapidly from confrontation to conflict
- Major Iranian military provocation: Attack on US or allied assets
Warning Time Assessment
If S2 indicators begin appearing:
- Limited strikes: 2-4 weeks preparation visible through OSINT indicators
- Sustained campaign: 4-8 weeks preparation; multiple carrier groups, forward logistics
- Israeli unilateral action: Shorter warning time (days to weeks); would likely be preceded by US-Israel diplomatic rupture
S3: COMPREHENSIVE DEAL INCLUDING MISSILES (15%)
Indicators That S3 Is Becoming More Likely
| # | Indicator | Observable? | Current Status |
|---|
| S3-1 | Iran signals willingness to discuss missile range limits | Yes | Currently rejected |
| S3-2 | Side channel on missile/regional issues opens | Partially | Not observed |
| S3-3 | Russia or China offer to mediate missile component | Partially | Not observed |
| S3-4 | Iranian domestic situation deteriorates further, forcing broader concessions | Partially | Ongoing crisis |
| S3-5 | US offers extraordinary security guarantees to Iran | Partially | Not observed |
| S3-6 | Netanyahu expresses cautious support for emerging framework | Yes | Currently opposes |
| S3-7 | IRGC factional shift toward pragmatism | Partially | Not observed |
Assessment
S3 is the least likely negotiated outcome because it requires Iran to cross its most firmly held red line (missiles). The only scenario where S3 becomes plausible is if Iran's domestic crisis escalates to a point where regime survival requires immediate and comprehensive sanctions relief, AND the US offers extraordinary incentives (security guarantees, major economic packages) that make missile constraints palatable. Historical precedent (Libya 2003) suggests this is possible but rare and requires unique conditions.
S4: INDEFINITE STALEMATE (15%)
Indicators That S4 Is Unfolding
| # | Indicator | Observable? | Current Status |
|---|
| S4-1 | Talks continue but no substantive progress for 3+ months | Partially | Too early to assess |
| S4-2 | Both sides declare commitment to process without results | Yes | Not yet |
| S4-3 | Military posture maintained but not escalated | Yes | Current status |
| S4-4 | Sanctions enforcement remains inconsistent (China continues purchases) | Yes | Current status |
| S4-5 | Iranian protests subside without resolution | Partially | Ongoing |
| S4-6 | US attention shifts to other priorities (elections, other crises) | Partially | Not yet |
| S4-7 | Iran gradually reconstitutes nuclear capability under continued talks cover | Partially | Possible but not confirmed |
Assessment
S4 is a "drift" scenario -- the absence of either decisive deal or decisive rupture. It is inherently unstable because the factors creating current tension (economic crisis, nuclear reconstitution, closing military window) will eventually force a more decisive outcome. S4 is most likely as a transitional state lasting 6-12 months before resolving into S1, S2, or the wild card.
WILD CARD: IRANIAN NUCLEAR BREAKOUT (5%)
| # | Indicator | Observable? | Status |
|---|
| WC-1 | IAEA detects enrichment to 90%+ at any facility | Partially | No access currently |
| WC-2 | Intelligence reports of weaponization activity | Classified | Unknown |
| WC-3 | Iran announces NPT withdrawal | Yes | Threatened only |
| WC-4 | Unexplained construction at military (non-declared) sites | Partially | Pickaxe Mountain is monitored |
| WC-5 | Iran conducts nuclear-relevant test (detonation, implosion) | Yes | Not observed |
| WC-6 | Major disruption in IAEA monitoring beyond current gap | Partially | Current gap is already severe |
Assessment
The wild card scenario is low probability but extremely high consequence. Its probability is elevated above baseline specifically because of the 400+ kg of missing enriched uranium. If this material was relocated and Iran has access to hidden centrifuge capacity, the timeline to a weapon could be months rather than years. The 8-month IAEA verification gap is the longest since Iran's nuclear program was discovered, creating significant uncertainty.
MONITORING PRIORITIES

- Status of second round of US-Iran talks (scheduling, format, participants)
- IAEA access to Iranian facilities (any change in cooperation)
- US military force posture changes in the region
- Netanyahu's public messaging on Iran (any shifts from current position)
- Iranian enrichment-related activities (any indicators of resumption)
Tier 2 (Monitor Weekly)
- Israeli coalition dynamics (budget vote, Smotrich/Ben Gvir positions)
- Iranian economic indicators (rial, inflation, oil export volumes)
- Gulf state diplomatic activity on Iran
- Trump administration internal messaging on Iran (Rubio, Vance, Witkoff)
- Chinese purchases of Iranian oil (volume, terms)

DECISION POINT TIMELINE
| Timeframe | Key Decision Point | Why It Matters |
|---|
| This week (Feb 10-14) | Israeli budget first reading | Determines March 31 coalition survival |
| Next 2 weeks | Second round of US-Iran talks | Success/failure sets trajectory |
| March 31 | Israeli budget deadline | Coalition dissolution trigger |
| April-May 2026 | US mid-year policy review | Administration recalibration point |
| June 2026 | Possible Israeli elections | New government could change Iran calculus |
| 6-12 months | Military leverage window | Pickaxe Mountain / reconstitution erodes leverage |
| 12-24 months | Pickaxe Mountain completion | Could create unreachable nuclear sanctuary |
