War in Ukraine: The Grinding Attrition

Russia's full-scale invasion of Ukraine, launched on February 24, 2022, has entered its fifth year with no definitive resolution in sight. What began as a multi-axis offensive aimed at the rapid capture of Kyiv has contracted into a grinding war of attrition concentrated along a roughly 1,000-kilometer front line in eastern and southern Ukraine.

Neither side has achieved a decisive strategic breakthrough since Russia's 2022 withdrawal from the Kyiv and Kherson regions. The conflict has consumed an enormous toll on both sides. UK Defence Intelligence estimated Russian forces sustained approximately 430,000 killed or wounded in 2024 and a further 415,000 in 2025 (UK Ministry of Defence, published via Kyiv Independent, 2026-01-14). Ukraine does not disclose comprehensive military casualty figures. Both figures carry significant uncertainty given the information restrictions imposed by both governments.

Background

The current conflict's roots extend to 2014, when Russia annexed Ukraine's Crimean Peninsula and backed separatist forces in the Donbas region. Eight years of low-grade conflict in eastern Ukraine preceded the 2022 escalation. Ukraine's pro-Western political orientation following the 2014 Euromaidan revolution, its pursuit of NATO membership, and Russia's stated concerns about Western military infrastructure near its borders formed the political context Moscow cited to justify its 'special military operation.'

The international response to the invasion was swift. The United States, European Union, and United Kingdom imposed sweeping economic sanctions on Russia and authorized large-scale military and financial support to Ukraine. Donor countries tracked by Germany's Kiel Institute, including the United States and EU member states, had committed an estimated €400 billion (about $430 billion) in total aid to Ukraine as of December 2024, though a substantial share remained unallocated (Kiel Institute for the World Economy, Ukraine Support Tracker, 2024-12-01).

Current Situation

As of the war's fourth anniversary in February 2026, Russian forces occupied approximately 20 percent of Ukraine's internationally recognized territory (Al Jazeera, citing Institute for the Study of War and Ukrainian military data, 2026-02-24), including Crimea, most of Luhansk, roughly half of Donetsk, significant portions of Zaporizhzhia and Kherson oblasts, and a thin strip of territory seized in the Kharkiv and Sumy regions following renewed Russian offensives in 2024 and 2025.

Combat activity is highest along the Donetsk axis, where Russian forces have made slow but sustained gains toward Chasiv Yar and Kostyantynivka. Long-range drone and missile strikes on Ukrainian cities, energy infrastructure, and logistics networks occur near-daily on both sides. Ukraine conducts regular strikes on Russian territory, including oil refineries, ammunition depots, and air bases in Kursk, Belgorod, and Voronezh oblasts.

Both militaries have heavily integrated first-person-view (FPV) drones, electronic warfare systems, and AI-assisted targeting into their operations. Drone warfare dominates tactical engagements to a degree unprecedented in prior conventional conflicts.

Key Actors

The Ukrainian Armed Forces, numbering roughly 900,000 active personnel with significant foreign-trained units, are supported by NATO-standard weapons systems including U.S. HIMARS rocket artillery, Leopard 2 and Abrams tanks, and F-16 multirole aircraft. Ukraine's military is formally advised by NATO personnel but operates independently.

Russia deploys a combination of regular military units, the National Guard (Rosgvardia), private military formations with roots in the now-fragmented Wagner Group, and a contingent of North Korean ground troops — roughly 11,000, including about 10,000 combat troops and 1,000 engineers, stationed in Russia's Kursk Oblast at the start of 2026 (South Korea's National Intelligence Service, via Kyiv Independent, 2026-02-13).

The United States remains Ukraine's principal backer, with ongoing debates in Congress over the scale and conditions of future support. European NATO allies have collectively increased defense spending and taken on greater burdens of direct military aid.

Outlook

Peace talks have stalled repeatedly over core disagreements. Russia insists any settlement recognize its territorial acquisitions; Ukraine and its Western partners have rejected any ceasefire that legitimizes Russian occupation. The Trump administration's 2025 push for a negotiated settlement produced informal contacts but no framework agreement.

The conflict's trajectory depends heavily on the sustainability of Western support for Ukraine and Russia's ability to absorb economic and military attrition. A freezing of the front lines along current positions — without a formal peace treaty — remains the most probable near-term outcome according to most foreign policy assessors.
