Again membership in EU has nothing to do with membership with NATO. Its just that geographically those to organizations iverlap. Sweden and Finland are EU memebr since long time ago but are not NATO members. France has been in and out of NATO.
Again the problem is Ukraine being armed to become a anti-Russian stooge. Russia dont care if Ukrainians eat McDonalds and wear french perfumes. Big powers in Europe didnt either want Ukraine to bevome a NATO member, because they knew the antgonizing effect it would have. Yet that is exactly what US and UK pushed for, in the end destabilizing entire continental europe. Mission accomplished!
Most EU members are NATO members. If Sweden and Finland are not NATO members it was by design.
NATO decisions need to be unanimous. If big powers in Europe did not want Ukraine to be NATO member why did Putin attack Ukraine ? Try Logic 101
