A direct military conflict between the United States and Russia or China occurs before 2028.
Public interest centers on near-term risks of global war. Resolves positively if direct, official kinetic clashes occur between the US military and Russian or Chinese forces.
Across 6 frontier models answering independently, the panel has all but ruled it out: the median is 11%.
They broadly agree, 14 points between GPT at 18% and Gemini at 4%.
Nothing is settled until 1 Oct 2029, when the outcome is checked against sources and every number above gets a permanent score.

It turns mainly on whether a Taiwan or NATO crisis outruns strong incentives to contain fighting below US–Russia/China combat.
- Cold War precedent is favorable: even Korea, Berlin, Vietnam, Afghanistan and Ukraine avoided official US–Soviet kinetic clashes.
- Beijing would have to initiate or sustain a Taiwan blockade/invasion, or Moscow attack NATO, before October 2029; both face major deterrents.
- A Chinese strike on US forces responding to a Taiwan quarantine, or Russian casualties from a NATO clash, would sharply raise this estimate.

Hinges on whether Taiwan or a Russia-NATO flashpoint escalates into acknowledged direct US-Russia/China military clashes.
- Both nuclear powers and the US have strong deterrence incentives to avoid direct kinetic clashes, favoring proxy/gray-zone conflict instead.
- Taiwan Strait tensions and NATO-Russia friction (Baltic airspace, Black Sea) are the main plausible triggers but no current trajectory points to imminent direct clash.
- Base rate for great-power direct kinetic conflict in any three-year window since 1945 is very low, though current tensions are elevated versus historical norm.

This turns on whether a Taiwan blockade or Baltic incident crosses into US forces firing on Chinese or Russian units.
- US and Russian forces have clashed directly before (1999 Pristina, 2018 Khasham), but those were not official state-on-state exchanges, so the base rate for true direct…
- China's 2027 PLA centenary and Taiwan pressure window is the most plausible trigger, but Beijing has consistently avoided direct US firefights, preferring gray-zone…
- The single development that would most change my mind is a declared blockade of Taiwan or a lethal Russian attack on NATO airspace, which would sharply raise the odds.

Whether a Taiwan invasion or Ukraine NATO clash forces official US-Russia/China shooting before 2028.
- Xi has not ordered a 2027 Taiwan campaign; PLA amphibious readiness and US/Japan deterrence still make invasion a high-cost gamble.
- US and Russia have kept Ukraine kinetic contact limited to drones and deniable strikes; neither has crossed into declared force-on-force.
- Great-power war base rate since 1945 is near zero; only a sudden, public kinetic exchange (not proxies) would flip this.

Mutual nuclear deterrence and de-escalation protocols will keep high-friction encounters from turning into direct military clashes.
- The 15-month window through 2027 is too tight for planned operations like a Taiwan invasion given current PLA readiness indicators.
- Despite Ukraine and South China Sea proxy tensions, Washington, Moscow, and Beijing maintain strict rules of engagement to avert war.
- A catastrophic mid-air intercept or naval collision causing casualties would immediately test de-escalation channels, raising odds.

Direct US-Russia or US-China kinetic exchange requires an escalation spiral neither side currently wants.
- Since 1945, zero direct US-Russia or US-China military clashes despite Korea, Vietnam, Cuba, Syria—base rate is effectively zero over 80 years.
- Russia is bogged down in Ukraine and China's PLA has no active combat; neither has a theater where accidental contact with US forces is imminent.
- The one realistic trigger would be a South China Sea intercept or a NATO-Russia border incident escalating beyond signaling; watch for any US carrier group loss or PLA…
