Ukraine isn’t Europe. Ukraine doesn’t have euros , gold, grain or minerals (out of the ground). And the men have been killed , so they don’t have any way to get that to pay for the weapons
You asked “What can europe fund the war with?” Did you mean to write “Ukraine” instead of “europe”? Otherwise it seems weird to say that the EU can’t take euros, give them to manufacturers in the EU, and disagree the weapons to Ukraine.
