Even if Ukraine gets to force Russia out of its regions and the war is officially over, every country west of Russia understands the ever-looming threat, so I don’t know if Ukraine would want to touch some of its most experienced and battle-ready units. At the same time, joining the EU could also mean stricter enforcement of hate speech laws so that if anybody who decides to take their ideology beyond their personal space and attack others faces judgement. As it’s been said, there’s not much support for the far-right parties among the Ukrainian population, so that part of the ideology is less of a threat.
