Ukraine continues to defend against Russian aggression and the Kremlin’s attempt to destroy Ukrainian statehood and identity despite growing difficulties two years after the start of Russia’s full-scale invasion. Two years ago Russia launched a full-scale war of conquest to overthrow the Ukrainian government and forcibly install a pro-Russian regime firmly under Moscow’s control. Russian forces drove on Kyiv from several directions and struck at Kharkiv, Kherson, Mariupol, and other Ukrainian cities. Russian President Vladimir Putin expected Ukrainians to welcome his forces or flee. Instead, Ukrainians fought for their freedom. They stopped the Russian drives on Kyiv and Kharkiv cities, stopped the Russian advance on Mykolayiv and Odesa cities, and fought Putin’s troops to a standstill along the rest of the line. Then, armed with experience, courage, determination, and growing Western aid, Ukraine struck back. Ukrainian forces drove the Russians from Kyiv and away from Kharkiv and liberated large swathes of territory in northeastern Ukraine. They liberated Kherson City and forced Russian forces off the west (right) bank of the Dnipro River. They ended the threat to Ukraine’s existence for the time.

The Houthis claimed that Saudi Arabia and the United States conducted combined airstrikes in Houthi-controlled territory on February 23, likely to pressure Saudi Arabia to exert its influence on the United States to decrease US strikes targeting Houthi military assets.

Ukrainian officials reported that Ukrainian forces shot down a Russian A-50 long-range radar detection aircraft on the night of February 23 – the second such aircraft shot down in 2024

Russian Security Council Deputy Chairperson Dmitry Medvedev said that Russia would likely have to seize Kyiv sooner or later while identifying Russia’s possible further territorial objectives in Ukraine. Medvedev responded in an interview published on February 22 to a question asking if there will “still be any part of Ukraine left that [Russia] will consider as a legitimate state, whose borders [Russia] will be ready to recognize.” Medvedev stated that Russia must “ensure its interests” by achieving the goals of the “special military operation” as laid out by Russian President Vladimir Putin – referring to Russian demands for Ukraine’s “demilitarization,” “denazification,” and neutrality. Medvedev reiterated Russia’s intention of changing the government in Ukraine, stating that the Ukrainian government “must fall, it must be destroyed, it must not remain in this world.” Medvedev claimed that Russia must create a “protective cordon” in order to protect against “encroachments on [Russia’s] lands,” including shelling and active offensive operations. Medvedev stated that he does not know where Russia should “stop” but that Russia “probably” must seize and occupy Kyiv “if not now then after some time.”

The pro-Russian breakaway region of Transnistria may call for or organize a referendum on Transnistria’s annexation to Russia at a recently announced Transnistrian Congress of Deputies planned for February 28. The pretext for such a call would be the purported need to protect Russian citizens and “compatriots” in Transnistria from threats from Moldova or NATO or both. Russian President Vladimir Putin could, in the most dangerous course of action, declare Russia’s annexation of Transnistria during his planned address to the Russian Federal Assembly on February 29, although that appears unlikely. Putin will more likely welcome whatever action the Transnistrian Congress of Deputies takes and offer observations on the situation. ISW offers this assessment as a warning for a high-impact event of indetermined probability. Moldovan government officials state that the situation in Moldova is unlikely to worsen as of February 22.

Prominent independent Russian milblogger Andrei Morozov reportedly committed suicide on February 21 after refusing the Russian military command’s orders to delete his reports about high Russian casualty rates around Avdiivka. Morozov (also known under the alias Boytsovskiy Kot Murz) was a sergeant in the Russian 4th Separate Motorized Rifle Brigade (2nd Luhansk People’s Republic’s [LNR] Army Corps) and an avid critic of the Russian military command and the Ministry of Defense (MoD). Morozov published a lengthy suicide note in which he stated that an unnamed Russian colonel ordered him on February 20 to remove his February 19 report that claimed that 16,000 Russian personnel died in combat during Russian offensive operations in Avdiivka.

Russian forces are conducting a cohesive multi-axis offensive operation in pursuit of an operationally significant objective for nearly the first time in over a year and a half of campaigning in Ukraine. The prospects of this offensive in the Kharkiv-Luhansk sector are far from clear, but its design and initial execution mark notable inflections in the Russian operational level approach.

Ukraine has been defending itself against illegal Russian military intervention and aggression for 10 years. Russia violated its commitments to respect Ukrainian sovereignty and territorial integrity and began its now decade-long military intervention in Ukraine on February 20, 2014 when Russian soldiers without identifying insignia (also known colloquially as “little green men” and, under international law, as illegal combatants), deployed to Crimea. The deployment of these Russian soldiers out of uniform followed months of protests in Ukraine against pro-Russian Ukrainian president Viktor Yanukovych for refusing to sign an association agreement with the European Union (EU) that the Ukrainian Rada had approved.The Yanukovych government killed and otherwise abused peaceful Ukrainian protestors, leading to an organized protest movement calling for Yanukovych’s resignation. This Ukrainian movement — the Euromaidan Movement — culminated in Ukraine’s Revolution of Dignity during which the Rada voted to oust Yanukovych who then fled to Russia with the Kremlin’s aid. Russian President Vladimir Putin viewed these events as intolerable and launched a hybrid war against Ukraine as the Euromaidan Movement was still underway with the goal of reestablishing Russian control over all of Ukraine.

Russia’s war in Ukraine is a war for people, not just land. The lives, freedom, and identities of nearly five million Ukrainians currently under Russian occupation and the nearly five million more whom the Kremlin has illegally deported to Russia, as well as the millions who have fled their homeland to other parts of Ukraine or abroad are at stake.

The tempo of Russian offensive operations near Avdiivka has reportedly dramatically slowed following the Russian seizure of Avdiivka. Ukrainian Tavriisk Group of Forces Spokesperson Dmytro Lykhoviy reported on February 19 that the number of Russian attacks in the Avdiivka direction significantly decreased in the past day and that Russian forces are currently regrouping and conducting clearing operations in Avdiivka. Lykhoviy noted that Russian shelling and aviation activity has also significantly decreased in the area. Ukrainian officials reported that Ukrainian forces have withdrawn to a new line of defense, which Ukrainian forces previously prepared in advance and fortified at “several levels.” Russian forces will likely have to conduct an operational pause before resuming significant offensive operations in the Avdiivka direction or will have to transfer additional reinforcements from other sectors of the front to the area to prevent operations near Avdiivka from culminating. Russian forces have reserves available for such reinforcement in other sectors, but ISW has observed no indication that the Russian command is moving those reserves toward Avdiivka at this time.
