In 2023, allies allocated €36 billion in military aid to Ukraine, representing a 14% decrease from the €41.1 billion provided the previous year. This information was reported by the Kiel Institute, which monitors military, financial, and humanitarian assistance promised and delivered to Ukraine since Russia's renewed invasion in February 2022. The decrease in aid raises concerns about the Ongoing Support for Ukraine amidst escalating conflict with Russia.

From 2022 to 2024, the United States contributed approximately half of the total military assistance to Ukraine. However, with the anticipated return of former President Donald Trump to the White House in early 2025, U.S. aid is expected to halt, which could significantly impact Ukraine’s defense capabilities. In response, European nations have made considerable efforts to fill this gap, increasing their overall military support by 67% in 2025 compared to the average from 2022 to 2024.

The Kiel Institute warns that without the European nations’ intervention, the consequences of the U.S. withdrawal could be even more devastating for Ukraine. Additionally, the report indicates a growing disparity in the support provided by European countries, with 95% of the military assistance coming from a limited group of nations. This uneven distribution highlights the need for more unified and equitable support from the European community towards Ukraine's defense against ongoing aggression from Russia.
