Israel x Lebanon diplomatic meeting by September 17, 2026?

• The US State Department publicly stated that the Israeli and Lebanese ambassadors would meet in Washington to discuss implementation of a security agreement, and an announced convening by the host government is strong evidence the event was scheduled within the market window.
• Ambassadors to the US acting in an official capacity on security-agreement implementation plausibly satisfy the resolution rule's definition of representatives authorized to engage in diplomacy, and the rule appears to also count indirect formats, widening what qualifies.
• Countervailing signal: President Aoun's Sept 12 statement of 'no new negotiations' suggests Beirut is publicly distancing itself, raising real risk of cancellation, postponement beyond Sept 17, or reclassification of any contact as non-qualifying.
• The retrieval explicitly could not establish that the Washington meeting actually took place; if it had occurred by Sept 13-15, confirmation would likely be available, so silence modestly lowers the estimate.
• With only ~3 days left, time decay is severe: even a genuinely planned meeting that slips a few days resolves NO, so I cut well below the base rate rather than trusting the announcement alone.

What would change it: Confirmation before the deadline that the ambassadors met in Washington (or any qualifying official Israel-Lebanon contact occurred) would push this to near-certain YES; a Lebanese or Israeli statement cancelling the Washington meeting would push it near NO.

Base rate: Announced near-term meetings hosted and confirmed by a credible third-party convening power typically occur as scheduled, roughly two-thirds to three-quarters of the time; this is my stated estimate for the class, as no retrieved fact supplies a rate.
