The EU doesn't need nukes but having plentiful air defense systems and interceptor drones would go a long way. Magazine depth is still an issue for a lot of countries too.
Russia launched a full invasion of Ukraine in early 2022. If it's 2027 and we're staring down the barrel of an actual Russian attack on a NATO member I don't want to hear "we don't have air defense systems" or "at this point planes wouldn't help because it takes two years to train pilots."
