Although Kiev is grateful to its allies for the military aid they have sent, Ukraine needs at least 10 times as much, Deputy Foreign Minister Andrii Melnyk said on Saturday.

A former Ukrainian ambassador to Berlin who has at times been criticized for his comments, Melnyk has called on allies to give Kiev military aid equal to 1 percent of their country’s GDP. Doing so would amount to a gigantic increase in military aid to Ukraine.

“We are grateful to our allies for their military assistance. But, it is not enough! Ukraine needs tenfold to end the Russian invasion this year,” Melnyk wrote on Twitter.

In the case of Germany alone, the largest economy in Europe, this would translate to more than $39 billion. Ukraine’s deputy foreign minister points out that these sums would pale in comparison to spending during the Second World War.

To date, the estimated value of allied aid to Ukraine is estimated at nearly $55 billion, according to Melnyk.
