Russia's renewed winter energy war on Ukraine and an intensifying widening of Xi's PLA purge headline today's outlook, as a catastrophic Nepal flood (760+ dead) settles into a prolonged displacement emergency and NATO institutionalizes Ukraine's drone-warfare lessons.

The base rate for wartime trilateral leader summits absent pre-negotiated terms is very low — Minsk/Normandy formats required months of preparatory diplomacy, not an intelligence-channel proposal. Leader profiles reinforce this: Putin (BVI 5) operates on weeks-to-months deliberation and de-escalates only via face-saving formulas that lock in gains — no such formula exists now. Xi-style patience is absent here; the relevant blocker is that no ceasefire scaffolding has been built. The wildcard is Trump (BVI 8), whose escalate-then-claim-victory cycle could manufacture a photo-op summit on short notice; this is the main reason I don't push higher than the high-70s. But a genuine THREE-leader meeting (not a bilateral Trump-Putin) requires Zelensky's buy-in, and his profile shows he rejects deals he considers capitulation. No active event chain for summit negotiations was found, confirming the story is not in a confirmation stage. The Russia-Ukraine chain sits firmly in escalation (Russia preparing mass energy strikes, ~2,000 drones/week). I set 0.77, marginally above the analyst/Skeptic 0.72, because the trilateral (vs bilateral) framing raises the bar and the escalation signals are strong. Pillars: historical parallels, power dynamics, regime stability.
