There was no negotiated settlement between Russia and Ukraine brokered by Western countries/the EU in the "next several months" after Sept. 10, 2022 (i.e., by early 2023), nor in the years since. Early negotiations in 2022 (Belarus, Istanbul) collapsed without a deal, and Ukraine’s National Security and Defence Council formally banned direct talks with Putin in September 2022, a ban that has remained in place, making such a settlement politically impossible. (euronews.com) As of January 2024, major outlets still described Russia and Ukraine as "nowhere near talks," with both sides holding incompatible conditions for peace. (cnbc.com) Fighting not only continued but intensified over winter 2022–23 during Russia’s winter offensive, confirming there was no ceasefire‑based settlement. (en.wikipedia.org)

Europe’s acute 2022 energy crisis eased during and after the 2022–23 winter, but this was due to factors like a milder winter, demand reduction, high storage levels, and a surge in LNG imports from the U.S. and Qatar—not a political deal with Russia. Analyses from early 2023 note that Europe "weathered the energy crisis" because of these measures and that the worst‑case scenarios for winter 2022/23 "did not happen," despite sharply reduced Russian gas flows. (hurriyetdailynews.com) Meanwhile, the EU repeatedly tightened energy‑related sanctions on Russia through 2023–25 rather than normalizing relations via a settlement, underscoring that no such bargain ended the crisis.

Because neither the predicted negotiated settlement nor its implied mechanism for ending the energy crisis occurred within the stated timeframe, the prediction is wrong.
