Over the past two years, Western support for Ukraine has undergone a major shift, with Europe taking on an increasingly dominant role while U.S. engagement has slowed and, more recently, stalled. According to the Kiel Institute for the World Economy’s Ukraine Support Tracker, European countries significantly ramped up their commitments in 2025, steadily expanding their share of total aid since the start of Russia’s full-scale invasion.
As our chart shows, the United States was the largest contributor during the first phase of the war, committing more than $118 billion (€100 billion) in government aid between 2022 and 2024 under the Biden administration. However, following President Donald Trump’s return to office in early 2025, U.S. support has effectively stalled, with no major new funding approved. In contrast, European countries have maintained and even accelerated their contributions, particularly throughout 2025.
In cumulative terms, Europe has now clearly overtaken the United States as Ukraine’s main backer, allocating more than $235 billion (€200 billion) in military, financial and humanitarian aid between January 2022 and February 2026, compared with roughly $135 billion (€115 billion) from the United States.
