SCENARIO PROBABILITIES Updated: Aug 7, 2026
Path 1 carries the largest share, 33%, because synchronizing two independently-commanded proxy structures under a public, disclosed warning is a harder execution problem than either of the two prior trees this desk has run assumed, and because CENTCOM's Jul 29-30 strikes specifically targeted the IRGC command centers, missile and drone facilities, and coastal surveillance nodes that would task and time a two-front campaign, days before this warning surfaced. Paths 2 and 3 split the bulk of the 'something happens' mass on precedent: an uncoordinated single-front strike (25%) has been the highest-frequency pattern all war, while a genuinely synchronized launch that still gets intercepted (20%) is weighted on naval and air-defense enforcement already holding at 49 redirected, 2 disabled, 2 boarded, and on the one confirmed Patriot intercept this crisis has logged, at Yanbu in July. Path 4, confirmed damage at a named node, sits lowest of the strike-lands paths at 14%: Abqaiq and Ras Tanura carry the heaviest post-2019 hardening in the kingdom, and this outcome is structurally continuous with a branch The Abqaiq Reversal already priced at 20% for a single-front trigger, so stacking a harder two-front requirement on top does not raise its odds. Path 5, that the warning itself is the instrument rather than a genuine operational plan, holds the smallest share, 8%, because multi-source corroboration across Saudi, US, and regional intelligence services is a harder pattern to manufacture as pure signaling than the single-source chatter this desk has discounted all war. Combined odds that a strike of some kind lands, Paths 2 through 4, total 59%; combined odds that the specifically warned coordinated campaign lands, Paths 3 and 4, total 34%. Both figures sit below the standing 85-90% deal-collapse band, currently near its top, and that gap is expected: deal collapse is driven by Iran's six-condition reopening position and the lapsed Aug 5 deadline, which hold regardless of how this tree resolves. This tree is additive to that band, not a subset of it, the same treatment given to the Iraq-specific risk in The Standing Authorization.
The Warning Holds 33%
Public disclosure and surged Patriot/ISR coverage deter execution; no strike attributable to either front materializes against the named targets through Aug 21 $78-84
Contained, Not Coordinated 25%
The Houthis or PMF strike on their own established tempo, indistinguishable from months of prior harassment; no evidence of genuine cross-front timing $82-88
Synchronized, Intercepted 20%
Both fronts fire within a tight window, confirming real IRGC coordination for the first time this crisis, but Patriot batteries and naval assets stop it short of confirmed damage $85-95
Synchronized, Damage Confirmed 14%
A coordinated launch penetrates defenses and Aramco or Saudi MoD confirms structural damage at Abqaiq, Ras Tanura, Yanbu, or Jubail $110-140
The Warning Was the Weapon 8%
No operational plan at this scale existed; the warning was surfaced as coercive signaling timed to Iran's hardened reopening terms, not a genuine strike order $76-82

Saudi, US, and regional intelligence sources warned Aug 6 of a threat this crisis has not logged before: Iraq-based militias and Houthi forces striking Gulf energy infrastructure, ports, and airports on one coordinated timeline, both under claimed IRGC direction. Today's alert carried the warning alongside a confirmed, separate Houthi strike that wounded 11 civilians in Saudi Arabia's Najran Province the same day, an incident this desk assesses as continuation of the existing bilateral border exchange, not part of the new campaign. Nothing has hit the named targets as of this writing. The question here is narrower than whether Iran escalates again. It is whether two proxy networks that have run on separate clocks for months, one built for friction with CENTCOM, one built for a bilateral fight with Riyadh, can actually fire on the same timeline. Five paths run through Aug 21 on whether they do, and what happens to Abqaiq, Ras Tanura, Yanbu, and Jubail if they manage it.
