The Russian Ministry of Defense (MoD) proposed on May 21 that the Russian government reassess Russia’s maritime borders in the Baltic Sea so that these borders “correspond to the modern geographical situation.” The Russian MoD produced a since-deleted document, which appeared on the Russian government’s legal portal on May 21, proposing that the Russian government should reassess the 1985 maritime borders in the Gulf of Finland because these borders were based on outdated “small-scale nautical navigation maps” developed in the mid-20th century.

How Delays in Western Aid Gave Russia the Initiative: From the Ukrainian Counteroffensive to Kharkiv

Russian forces have conducted offensive operations since Fall 2023 that aimed to convince the West to abandon its commitment to Ukraine, and prolonged US debates about security assistance likely convinced the Kremlin that its efforts had partially succeeded. The effects of continued delays in US and Western security assistance set conditions for Russian forces to make more significant gains on the battlefield than they had previously been able to make, and the Russian military command likely concluded that Russian forces would be able to collapse the Ukrainian frontline at some point in the near to medium term.
