Europe provided the vast majority of the funding: https://www.kielinstitut.de/topics/war-against-ukraine/ukrai...

Also, most recent developments on the battlefield are driven by Ukraine's own innovations - better drones, interceptor drones, their own cruise missiles, etc. All the lessons are being absorbed by Europe and the US.
