The United States conducts military strikes against Iran between November 4, 2026, and December 31, 2026.
President Trump suggested military action against Iran could escalate after the Nov. 3, 2026 midterm elections. Resolution requires verified direct US strikes on Iranian targets in that window.
Across 6 frontier models answering independently, the panel has all but ruled it out: the median is 14%.

Trump's post-midterm hint is cheap talk until force posture actually shifts toward CENTCOM.
- Trump floats strikes constantly but has ordered none on Iran in 2025-26 despite maximal pressure and Houthi exchanges.
- Carrier presence and bomber rotations in the Gulf would need to build weeks ahead; no such surge is publicly visible as of early October.
- Base rate for a US-Iran direct strike in any given two-month window is low single digits; the explicit post-election signal lifts it, but midterms also cut against a…

It turns on whether Tehran or its proxies trigger a post-election crisis Washington answers directly inside Iran.
- Trump would need to order strikes after Nov. 3, while the Pentagon would need actionable targets and regional basing access.
- Direct US attacks on Iranian territory are rare; recent confrontations usually favor proxy, cyber, or limited regional responses.
- Clear Iranian killing of US personnel, a nuclear breakout, or an attack on Gulf shipping would sharply raise the odds.

Hinges on whether Iran-US tensions escalate past diplomacy into direct strikes within this narrow 8-week window.
- Trump has floated post-midterm action but no concrete military buildup or ultimatum timeline has been confirmed as of Oct 2026.
- Historical base rate for US strikes on Iran in any given 2-month window is low absent a triggering incident (attack, nuclear breakout, hostage crisis).
- Watch for Iranian provocation (attack on US forces/allies, major nuclear escalation) or explicit Trump deadline-setting before midterms as the key swing factor.

Turns on Trump ordering verified strikes on Iran proper in the 8-week post-midterm window.
- Trump/Pentagon must green-light and execute by 31 Dec; existing tensions supply pretext but no new casus belli is required.
- Direct US strikes on Iranian soil have near-zero 2-month base rate (1988 tanker war, 2020 Iraq strike); rhetoric lifts odds yet war-escalation risk and midterm politics…
- A large Iranian attack on US/Israeli assets or nuclear breakout would most raise the probability.

Turns on whether Trump's post-midnight rhetoric converts into a concrete operational decision within 8 weeks.
- Base rate: The US has not struck Iran directly since 1988 (Operation Praying Mantis); in any given 2-month window, the prior is ~1-2%.
- Trump's threat is real but vague; no confirmed deployment of strike packages, no congressional authorization, and Iran's nuclear program is not in an imminent-breakout…
- A confirmed Iranian dash toward a nuclear weapon or a major proxy attack killing US troops in this window would be the single development that could push this above 30%.

Direct US strikes on Iranian soil require severe nuclear breakout or mass-casualty triggers that rhetoric alone rarely precipitates.
- A direct strike on Iranian territory in any random eight-week window has an empirical base rate under two percent over four decades.
- The Pentagon and regional allies consistently push back against overt war due to Strait of Hormuz closure and energy shock risks.
- Odds rise sharply only if Iran expels IAEA inspectors to dash for a bomb or directly kills dozens of US service members.
