The situation 1156 – May 16, 2025

• Ukrainian and Russian delegations met in Istanbul on May 16 but made little progress towards agreeing to a full ceasefire or a peace settlement to Russia's war against Ukraine.
• Medinsky highlighted that Russia is prepared to continue its war in Ukraine for years to come.
• The Kremlin has repeatedly publicly demanded that Ukraine cede all of Luhansk, Donetsk, Zaporizhia, and Kherson oblasts – even the territory that Russian forces currently do not occupy - but had not formally demanded that Ukraine cede all of Kharkiv and Sumy oblasts before the May 16 Istanbul meeting.
• ISW has consistently assessed that Russian President Vladimir Putin will not compromise in peace negotiations unless Ukraine and the West inflict significant battlefield and economic losses on Russia and force Putin to rethink his theory of victory.
• Russian President Vladimir Putin reportedly approved a series of command changes in the Russian military, including a new Commander-in-Chief of the Russian Ground Forces.
• Russian forces are continuing to expand their salient northeast of Pokrovsk and southwest of Toretsk, although it remains unclear whether the Russian military command will prioritize further advances towards Kostyantynivka or Pokrovsk during Summer 2025.
• Russia is unlikely to have sufficient manpower, materiel, and operational planning capabilities to conduct both an envelopment of Pokrovsk and a significant offensive operation toward Kostyantynivka in the coming months.
• Russian forces recently advanced near Toretsk, Pokrovsk, and Novopavlivka and in the Zaporizhia direction.
