A senior Ukrainian official reported that the Russian military intends to seize half of Ukraine by the end of 2026. Russian forces are highly unlikely to be able to make such large advances in such a narrow time frame, given Russia’s current offensive capabilities and assuming that the flow of Western aid to Ukraine continues. Ukrainian Presidential Office Deputy Head Colonel Pavlo Palisa told reporters on June 5 that Russia likely seeks to seize the full extent of Donetsk and Luhansk oblasts by September 1, 2025, and create a buffer zone along the northern Ukrainian-Russian border by the end of 2025. Palisa also stated that Russia intends to occupy the entirety of Ukraine on the east (left) bank of the Dnipro River and seize Odesa and Mykolaiv oblasts by the end of 2026, depriving Ukraine of access to the Black Sea. Western sources published a map on June 4 and 6 that Palisa reportedly presented to US officials and journalists. The map suggests that Russia intends to seize roughly 222,700 additional square kilometers of Ukrainian territory and hold a total of 336,300 square kilometers by the end of 2026 – almost double the roughly 162,000 total square kilometers that Russia held as of the first month of Russia's initial full-scale invasion of Ukraine in 2022. The total area of Ukraine is roughly 603,500 square kilometers.
Palisa’s map of purported Russian operational objectives suggests that Russian forces will attempt to seize and leverage positions in Zaporizhia and Dnipropetrovsk oblasts to support concurrent efforts to seize the remainder of Donetsk and Luhansk oblasts prior to September 1, 2025. Palisa’s map suggests that the Russian military command does not intend for Russian forces to seize Zaporizhzhia City by September 1. Palisa’s map suggests that Russian forces seek to leverage these positions to eventually seize Zaporizhzhia City, which is consistent with the Russian government’s formal territorial demands for all Zaporizhia Oblast.
It remains unclear on what basis the Russian military may be able to seize the remainder of Donetsk Oblast within the next three months or even advance the 50 to 80 kilometers from the current Russian frontline to the administrative boundaries of Donetsk Oblast. Russian forces have spent the last 15 months advancing between 30 and 50 kilometers from the outskirts of Avdiivka to their current positions northeast and southwest of Pokrovsk, a far slower rate of advance than the one necessary to seize all of Donetsk Oblast by September 1. The rate of Russian advance as depicted by the map also appears to assume that Russian forces will be able to fight through the Kostyantynivka-Kramatorsk-Slovyansk fortress belt – a series of fortified cities that form the backbone of Ukraine’s defensive positions in Donetsk Oblast – at a rate never demonstrated by Russian forces at any point during Russia’s full-scale invasion of Ukraine. Russian forces have not fought through a comparable town since Russian forces engaged in a year-long and pyrrhic effort to seize Bakhmut that ended in May 2023.
Palisa’s assessment posits that Russian forces would then sequentially attempt to seize the remainder of Kherson Oblast and create a “buffer zone” along the international border in northern Ukraine by the end of 2025. Palisa’s map suggests that Russian forces would attempt to ford the Dnipro River, retake the remainder of Kherson Oblast, marginally advance further in Dnipropetrovsk Oblast, and establish a defensible buffer zone along the international border in Chernihiv, Sumy, and Kharkiv oblasts by the end of 2025. The Russian military command would likely have to redeploy significant Russian forces from other areas of the frontline to accomplish these objectives, assuming Ukraine’s international partners continue supporting Ukraine.
Russian forces would struggle to seize the remainder of Kherson Oblast, as it would require crossing the Dnipro River, establishing a lodgement on the west (right) bank of the Dnipro River, seizing Kherson City, and then advancing further west and north to the oblast's administrative borders. Neither Ukrainian nor Russian forces have successfully conducted cross-river operations at scale across the Dnipro River since Russia’s withdrawal to east (left) bank Kherson Oblast in November 2022, and the establishment of significant Ukrainian defenses in west bank Kherson Oblast since liberating this area will only further hamper Russia’s ability to seize the remainder of Kherson Oblast.
A series of intensified, simultaneous Russian offensives into northern Chernihiv, Sumy, and Kharkiv oblasts would spread Russia’s manpower and materiel along the entire thousand-kilometer-long frontline and likely exacerbate existing constraints. Russia’s reported operational objectives through the end of 2025 are consistent with long-standing Russian demands that Ukraine concede the illegally annexed Luhansk, Donetsk, Zaporizhia, and Kherson oblasts and Crimea, however.
Key Takeaways:
- A senior Ukrainian official reported that the Russian military intends to seize half of Ukraine by the end of 2026. Russian forces are highly unlikely to be able to make such large advances in such a narrow time frame, given Russia’s current offensive capabilities and assuming that the flow of Western aid to Ukraine continues.
- The Russian military command’s purported objectives for 2026 extend far beyond Russia’s formal territorial demands and aim to seize a significant part of central Ukraine and most of southern and eastern Ukraine.
- Russia’s purported military campaign plans for 2025 and 2026 are consistent with long-standing Russian territorial objectives and recent statements by pro-Kremlin voices in the information space.
- The Russian military is likely unable to achieve its purported 2026 objectives, given the significant manpower and materiel losses Russian forces have sustained over the last three years of war and the Russian forces’ inability to achieve operational maneuver on the battlefield. Putin’s theory of victory depends on the Western alliance backing Ukraine, abandoning Ukraine as a necessary condition to bring about this scale of advance
- Russian forces conducted the second-largest series of missile and drone strikes of the war overnight on June 5 to 6.
- Ukrainian forces conducted a series of drone strikes against Russian military facilities, airfields, and defense industrial base (DIB) facilities overnight on June 5 to 6.
- Russia's Central Bank lowered its key interest rate for the first time since September 2022, likely prematurely due to increased Kremlin pressure to project economic stability.
- Russian forces recently advanced in Belgorod and Sumy oblasts and near Lyman and Velyka Novosilka.
