Ukraine thankfully haven’t had to defend themselves against Russian nuclear weapons though. But if you go down that road, it would’ve made no difference whether the EU gave them absolutely nothing, or even twice the amount of military aid they have already given. Use of nuclear weapons would have been catastrophic against Ukraine circa 2014 (poorly equipped), Ukraine circa 2022 (well equipped) and basically any non-nuclear country whether they're rich or poor.
