Russian President Vladimir Putin did not threaten an immediate nuclear attack to halt the Ukrainian counteroffensives into Russian-occupied Ukraine during his speech announcing Russia’s illegal annexation of Ukrainian territory. Putin announced Russia’s illegal annexation of Ukraine’s Donetsk, Luhansk, Kherson, and Zaporizhia oblasts on September 30 even as Ukrainian forces encircled Russian troops in the key city of Lyman, Luhansk Oblast, immediately demonstrating that Russia will struggle to hold the territory it claims to have annexed. Putin likely intends annexation to freeze the war along the current frontlines and allow time for Russian mobilization to reconstitute Russian forces. The annexation of parts of four Ukrainian oblasts does not signify that Putin has abandoned his stated objective of destroying the Ukrainian state for a lesser goal. As ISW assessed in May, if Putin’s annexation of occupied Ukraine stabilizes the conflict along new front lines, “the Kremlin could reconstitute its forces and renew its invasion of Ukraine in the coming years, this time from a position of greater strength and territorial advantage.”
