“Relatively late in the game the Ukrainians began asking for advice on where this thing was going and it became clear to us, clear to the Brits, clear to others that [Russian President Vladimir] Putin‘s main condition was buried in an annex to this document that they were working on,” she said of the deal being discussed by the Russian and Ukrainian delegations in Türkiye’s largest city.

The proposed agreement included limits on the kinds of weapons that Kiev could possess, as a result of which Ukraine “would basically be neutered as a military force,” while there were no similar constraints on Russia, the former diplomat explained.

“People inside Ukraine and people outside Ukraine started asking questions about whether this was a good deal and it was at that point that it fell apart,” Nuland said.
