The Ukraine-Russia conflict, now in its fifth year, has evolved into a war of endurance and adaptation. Ukraine aims to make the war unsustainable for Russia by minimizing territorial losses and increasing economic costs. The initial Russian invasion, branded as a 'special military operation', has become Europe's largest conventional conflict since World War II.
Ukraine's strategy focuses on pushing Russian casualties beyond Moscow's recruitment capacity and targeting Russia's energy export infrastructure. Despite initial setbacks, Ukraine performed well in 2025, ending the year on a stronger footing. The situation is challenging, but not dire, as Kyiv enters 2026 with a focus on realigning relations with Washington and sustaining Western support.
The Early Years: A War of Perceptions and Expectations
In February 2022, Ukraine faced a perceived disaster, with U.S. intelligence predicting a Russian invasion. However, Ukraine's government remained skeptical until the final days, and key allies had a different interpretation. The Russian plan, based on faulty assumptions, aimed to isolate Ukrainian forces and shock the leadership. Fortunately, these assumptions proved false, and Ukraine rallied Western support.
Russian forces were defeated in Kyiv and the south, but they adapted, leveraging their firepower advantage. Ukraine's volunteer-swelled ranks, aided by Western intelligence, exhausted the Russian offensive by summer 2022. Successful Ukrainian offensives in Kherson and Kharkiv led to a Russian rout, but these gains set unrealistic expectations for a swift victory.
Moscow launched a partial mobilization, committing to a long war. The costly battle for Bakhmut signaled the difficulty of the road ahead. Ukraine's focus on Bakhmut overshadowed its plans for a decisive 2023 summer offensive, which failed due to prepared Russian defenses and a lack of surprise.
The Current Fight: A War of Adaptation and Attrition
The war has evolved from a conflict defined by speed and maneuver to one characterized by adaptation, attrition, and reconstitution. Technological innovation and new tactics have changed the battlefield every three to four months. Ukraine leverages Western support, while Moscow mobilizes its resources, including Soviet-era equipment, with support from China, North Korea, and Iran.
The current battlefield dynamic features porous lines, with Ukrainian forward positions as pickets and Russian forces infiltrating past them. The 'kill zone', a gray area of overlapping engagement zones, is a crucial battleground for drone superiority. The fighting has shifted to drone units and artillery, with both sides employing precision strike capabilities and attack drones against high-value targets.
Russia's small infantry groups and lightly motorized troops struggle to generate momentum for breakthroughs. This has limited Russia's ability to exploit localized superiority in drone units, leading to a year-round offensive slog. Russian forces have been grinding through the front since 2024, conducting small-scale operations across a vast frontline.
A Tale of Two Strike Campaigns
Both sides have expanded strike campaigns against critical infrastructure and defense industrial production. Russian strikes on Ukrainian infrastructure and cities have been particularly brutal during the colder winter months. Ukraine's electric grid faces growing pressure, leading to rolling blackouts. Russia has increased missile production, with a near-exponential growth in long-range attack drones. Ukraine faces thousands of drone strikes combined with cruise and ballistic missiles.
Ukraine's strikes against Russian energy infrastructure have disrupted fuel supplies and suppressed energy export revenue. By 2025, Ukrainian strikes started impacting Russian refining and export infrastructure. Ukraine aims to sap Russia's financial ability to sustain the war, as Russia faces economic stagnation, a growing deficit, and declining oil revenues.
Challenges for 2026: A Race Against Time
Russia's combat efficiency is not improving despite tactical adaptations. The Russian military is preserving equipment but suffering larger manpower losses. Recruitment has been strong, but by 2025, almost all enlistees were replacements for combat losses. The negative trends are likely to worsen, with Moscow facing challenges in gathering recruits.
Ukraine has had some offensive successes, developing an effective approach using drones to isolate and degrade Russian forces. The Ukrainian armed forces consistently use technology to offset their manpower disadvantage. However, Ukraine faces challenges in maintaining combat strength at the front, with thousands of personnel absent and soldiers tired. As the fighting shifts to drone units and specialists, losses are increasingly difficult to replace due to specialized training requirements.
Ukraine has struggled with force management, forming new units without sufficient resources and creating imbalances. The 'not one step back' policy leads to the formation of salients, with Ukrainian forces enveloped by enemy advances. Some commanders misreport positions, unable to sustain defense against constant Russian assaults.
The War in 2026: A Regional Conflict
The war has taken on a regional character, with Russia and Ukraine expanding attacks against commercial shipping in the Black Sea. Ukraine has targeted Russia's shadow fleet, while Moscow has violated NATO members' airspace. These campaigns are likely to expand as deadlock prevails. Seemingly small changes can have significant ripple effects, as Ukraine recently blocked Russia's use of Starlink, affecting its drone and uncrewed ground vehicle operations.
In 2026, Ukraine aims to stabilize the frontline, find scalable solutions to Russian strikes, and use drones and cruise missiles to inflict economic damage on Russia. A shift in momentum depends on Ukraine's ability to control the battlespace and reclaim drone superiority. Russian forces currently enjoy an advantage in strike capabilities beyond 20 miles, which Ukraine must redress to achieve effects beyond attrition.
Russian President Vladimir Putin's bets on sustained pressure and diplomacy turning the U.S. against Ukraine proved wrong. The fighting's progression will inform negotiations, with the key question being the sustainability of Russia's offense versus Ukraine's defense. Battles suggest that Moscow's military prospects have not significantly improved, while economic strain mounts.
Wars are contests of will and endurance. Washington seeks a settlement by summer, but an artificial timetable is challenging. This conflict is not just about land; Moscow aims to impose its will on Ukraine and destroy its independent state identity. Ukraine faces challenges, but time is increasingly on its side, despite Moscow's portrayal.
Moscow cannot ignore the fundamental mismatch between its military means and political aims. The war's endurance and adaptation will shape its outcome, and the coming year will be crucial in determining the conflict's trajectory.
