Four years after Russia launched its full-scale invasion of Ukraine, the conflict has become a grinding war of attrition, marked by staggering casualties and a reshaping of Europe’s security landscape. As the fighting enters its fifth year, the human cost continues to mount, with an estimated 1.8 million soldiers killed, wounded, or missing on both sides, according to a recent report by the Center for Strategic and International Studies (CSIS). The war, which began on February 24, 2022, shows no immediate signs of abating, despite ongoing, U.S.-brokered negotiations aimed at securing a lasting peace.
The scale of the losses is immense. CSIS estimates that Russia has suffered approximately 1.2 million casualties since the start of the invasion, including up to 325,000 troop deaths – the largest number of troop deaths for any major power in a conflict since World War II. Ukraine’s military has also sustained heavy losses, with estimates ranging from 500,000 to 600,000 casualties, including up to 140,000 deaths. Ukrainian President Volodymyr Zelenskyy stated earlier this month that 55,000 Ukrainian troops have died in the war, with many more still missing. However, independent verification of these figures remains impossible, as neither Moscow nor Kyiv consistently releases detailed battlefield casualty reports. Russia last published figures in January 2023, reporting just over 6,000 military deaths.
The Civilian Toll and Impact on Infrastructure
The conflict’s impact extends far beyond the battlefield. The United Nations Human Rights Monitoring Mission has recorded 14,999 civilian deaths since the full-scale invasion, though officials acknowledge this is likely an underestimate. More than 40,600 civilians have also been injured. Tragically, at least 763 children have been killed in the war. Last year was the deadliest for Ukrainian civilians since 2022, with 2,514 deaths and 12,142 injuries – a 31% increase in civilian casualties compared to 2024, according to UN data.
Beyond the immediate loss of life, the war has caused widespread destruction of critical infrastructure. The World Health Organization (WHO) reported 2,881 Russian attacks affecting the provision of medical care in Ukraine since February 2022, a nearly 20% increase from the previous year. These attacks have included strikes on at least 2,347 healthcare facilities, as well as damage to vehicles and medical supply storage.
Territorial Control and Shifting Alliances
As of February 2026, Russia occupies 19.4% of Ukrainian land, according to the Institute for the Study of War. Even as Moscow has made incremental gains, securing just 0.79% more territory over the past year, the advance has reach at a significant cost in troops and equipment. Before the full-scale invasion, Russia controlled approximately 7% of Ukraine, including Crimea and parts of the Donetsk and Luhansk regions.
The dynamics of international support for Ukraine have also shifted. Foreign military aid to Kyiv decreased by 13% last year compared to the 2022-2024 average, according to the Germany-based Kiel Institute. A change in U.S. Policy under President Donald Trump, who halted weapons shipments paid for by the U.S., contributed to this decline. European countries have increased their military aid by 67% during the same period, attempting to offset the reduction in American support. Foreign humanitarian and financial aid to Ukraine also fell by 5% last year.
Displacement and Humanitarian Crisis
The war has triggered one of the largest displacement crises in recent European history. Approximately 5.9 million Ukrainian civilians have fled their country, with 5.3 million finding refuge in Europe, according to the UN. An additional 3.7 million Ukrainians have been displaced within the country. Ukraine’s pre-war population exceeded 40 million.
Volodymyr Zelenskyy has stated that Russian President Vladimir Putin has already started World War III, a sentiment reflecting the escalating global implications of the conflict. TVNZ provides further coverage of Zelenskyy’s remarks.
As negotiations continue, the fundamental issues of territorial integrity and postwar security remain unresolved. The U.S. Has reportedly told Ukraine it must sign a peace deal with Russia to receive security guarantees, according to Reuters. The next steps in the diplomatic process remain uncertain, but the immense human cost of the conflict underscores the urgent demand for a resolution. The focus now shifts to upcoming discussions between U.S. And European officials regarding continued aid packages for Ukraine, scheduled for early March.
