The Russian military offensive in Ukraine has plunged Europe into its most severe security crisis since World War II.

Trump has controversially blamed Ukraine for the war's onset, a point he discussed with Ukrainian President Volodymyr Zelensky during a meeting at the White House.

Since the invasion began on February 24, 2022, Ukraine has heavily relied on financial and military aid from Western allies.

In terms of military aid, the U.S. still leads with €65 billion, slightly ahead of European contributions.

Since Donald Trump's return to the White House on January 20, 2025, no new U.S. aid has been approved, with the last arms shipment of €500 million occurring on January 9.

For instance, Estonia and Denmark have contributed 2.0% of their GDP, while Germany's contribution stands at only 0.5%, and France, Spain, and Italy have contributed between 0.1% and 0.2%.

European nations have approved €138 billion in military, financial, and humanitarian assistance to Ukraine, surpassing the United States' commitment of €115 billion.

However, many European countries are contributing proportionally less than Nordic and Baltic states, according to the Kiel Institute for the World Economy.

In addition to financial support, Ukraine's allies have imposed sanctions on key sectors of the Russian economy to weaken Moscow's ability to finance its war efforts.
