While not directly participating in the war in Ukraine, countries around the world have been contributing to the defence of Ukraine via financial, humanitarian and military aid. In absolute terms, the largest supporter as of October 3 - by a very large margin - was the United States, with a total of €52.3 billion made up of €27.6 billion in military aid, €9.5 billion humanitarian aid and €15.2 billion in financial aid.
As this infographic using Kiel Institute for the World Economy data shows though, when it comes to a country's commitment in relative terms, the U.S. didn't come close to Latvia Estonia in the first eight months of the war. Latvia's contribution of €350 million equates to 1.01 percent of the country's GDP. The United States' financial input up to this point was equivalent to 0.25 percent of its economic output.
