Warning Thresholds
93% Prepare As If Attack Will Occur

At this level, the military force is complete, actively expanding, and no diplomatic off-ramp is visible. This is the point where the assessment shifts from analytical to actionable.

Anyone who needs to make decisions — journalists, policymakers, regional stakeholders, at-risk populations inside Iran — should assume operations are coming and begin preparing accordingly. The threshold is set here rather than higher because by the time final confirmation arrives, the window to act on it may already be closing.

95% Attack Is Imminent

At this level, EMCON (emissions control) has been observed — military aircraft transponders across the theater go dark simultaneously. There is no legitimate operational reason to go emissions-silent unless you are about to strike.

At 95%, operations are expected within 24 to 72 hours. This is not the first warning. It is confirmation of what was already warned at 93%.

70%
Sustained multi-week campaign
Operation LION & SUN: Joint US-Israeli strikes began 28 Feb. Presidential facility targeted. McMaster: 'extensive opening campaign.' 150+ combat aircraft at Salti, 42 at Lakenheath, 128 tankers = sustained tempo infrastructure. Force exceeds June 2025 by 2-3x. Regime change messaging (#FreeIran). Multi-day/multi-week operations likely.
Active
15%
Regional escalation (Hezbollah/proxies)
Iranian retaliation triggers multi-front war. Hezbollah activates northern front. Houthis target shipping. Iraqi militias attack US bases. ~525 ballistic missiles launched (June precedent). Strait of Hormuz closure. Energy infrastructure strikes. Regional conflagration beyond bilateral US-Iran conflict.
Rising
10%
Limited strike + ceasefire
Initial strikes target nuclear + military sites only. Iran restrains retaliation (unlike June). Backchannel negotiations via Oman. Trump accepts limited campaign. Ceasefire within 48-72 hours. Political face-saving on both sides. Lower probability given regime change messaging and force scale.
Declining
3%
Regime collapse / internal upheaval
Strikes decapitate IRGC leadership + presidential targets. Protests erupt. Military factionalism. Internet blackout fails. MEK/opposition groups capitalize. Regime legitimacy crisis accelerates. Pahlavi restoration symbolism (Lion & Sun) resonates. Low probability but operation name signals intent.
Uncertain
2%
Rapid negotiated settlement
Iran capitulates immediately. Accepts zero enrichment. Dismantles program under IAEA supervision. Regime survives via concessions. Extremely low probability given 20+ year nuclear program investment and revolutionary ideology. Trump regime change rhetoric makes diplomatic exit narrow.

Methodology
OSINT Sources & Calibration

This assessment is based entirely on open-source intelligence: ADS-B and ACARS flight tracking data, commercial satellite imagery, analysis from the OSINT community including MATA (Military Air Tracking Alliance), DefenceGeek, and Armchair Admiral, and cross-referenced political and diplomatic developments. No classified information is used.

Probability is anchored to observable military indicators — the disposition, composition, scale, and movement of deployed forces. Political context is treated as supporting information only and does not independently drive probability changes. Each change in probability requires a specific, predefined trigger to be met. The framework is calibrated against the June 2025 Operation Midnight Hammer precedent, which provides a baseline for force requirements, tanker ratios, and pre-strike indicator sequencing.

Why the Scale Never Reaches 100%

100% means strikes have begun. Bombs are falling and CENTCOM has issued a statement. Until kinetic action is observed, there is always residual uncertainty because the decision to strike rests with one person and can be reversed up to the final moment.

A breakthrough deal could emerge. An unexpected crisis could shift the calculus. A classified stand-down order would be invisible to us. The 3 to 5 percent gap between our analytical ceiling and absolute certainty is not a hedge — it is an honest acknowledgment that we are watching observable indicators from the outside, not sitting in the Situation Room.
