ISW Russian Offensive Campaign Assessment, June 2, 2025

Latest from the Institute for the Study of War.

Key Takeaways from the ISW:

  • Ukrainian and Russian delegations met in Istanbul on June 2 and only reached agreements about prisoner of war (POW) exchanges. Russia’s refusal to give Ukraine its memorandum with its terms for a peace settlement before the meeting ensured that the meeting was largely unproductive and further protracted the negotiation process.
  • Ukrainian and Russian media published the major points of both sides’ memorandums on June 1 and 2, respectively.
  • Russia’s memorandum reflects the Kremlin’s long-standing public demands for Ukraine to make significant territorial and political concessions while Russia offers no concessions of its own.
  • The Russian delegation dismissed Russia’s systemic kidnapping of Ukrainian children.
  • Russian forces appear to be intensifying efforts to widen the frontline in northern Sumy Oblast along three axes of advance north and northeast of Sumy City.
  • Open-source analysts continue to clarify the battlefield damage following the Ukrainian long-range drone strike series on June 1.
  • Ukrainian forces recently advanced near Velyka Novosilka. Russian forces recently advanced near Lyman, Chasiv Yar, and Toretsk.
