Or it could just end with mutual total nuclear annihilation of course.
Edit: now if they were to attack the eu over a decades long interference campaign with its member state democracies, funding anti eu parties, stoking separatist sentiments, and covertly subverting the fundamental pillars of its liberal democracies, on the other hand…
Poland alone has a population comparable to Ukraine, and a significantly larger economy.
If EU countries commit to a conflict, Russia has no chance. It makes nuclear escalation a real risk though.
