Uh… from the EU. That’s one of the points of the EU. It would essentially be an investment in the future of Ukraine, and thus, transitively, the EU itself, since Ukraine has begun the accession process.

More broadly: holy fuck am I sick of people whinging about doing the objectively right thing because iT’s tOo eXPeNsiVe.
We’ve finally gotten to a place where many major western nations will, every once in a while, do something not shitty, with at least some altruistic motivations - like helping Ukraine, and more generally, just pushing back on Russian and Chinese encroachment and expansionism.
I’m by no means claiming “The West” is perfectly virtuous - that’s obviously false. But still: for pretty much the first time in the history of civilization, you have countries that are kinda-sorta trying to do the right thing sometimes… and you want to nickel and dime that whole sentiment?
