The United States and European countries continue to pledge their support to Ukraine as Russia’s invasion drags on into its ninth month – and have backed their alliance with recurrent deliveries of advanced weaponry and money.

But despite Russian President Vladimir Putin’s threats to Western powers of nuclear strikes, neither the U.S. nor any Western European country, unified under the military coalition NATO, has actually declared it is part of the war.

The U.S. has provided US$17.6 billion in security assistance to Ukraine since Russia first invaded Ukraine in February 2022. But it can be difficult to track foreign aid and to distinguish between money that governments have promised and actually delivered. Some unofficial estimates place U.S. commitments to Ukraine made in 2022 much higher, at $40 billion.

European countries, meanwhile, have collectively donated an estimated 29 billion euros – or more than $28.3 billion – in security, financial and humanitarian aid in 2022 – not including additional aid to Ukrainian refugees.
