The second-ranked country, the United Kingdom, has pledged far less - just over $4 billion – in the given time frame.
In relative terms, however, both military aid commitments amount to approximately 0.1 percent of either country's GDP.
Looking at this metric, Ukraine's smaller neighbors contributed more to its war effort, for example Poland (military aid of 0.3 percent of GDP) or Estonia (0.8 percent). Even when combining military, financial and humanitarian aid delivered or pledged by the U.S. is added up, this only amounts to 0.2 percent the country's GDP.
Other big donors of military aid to Ukraine are Germany and Canada - even though their relative pledges only amount to 0.03 percent and 0.06 percent of their respective GDPs.
