That’s only for ICBMs. Nukes could be delivered by plane or cruise missile that don’t have the uncertainty related to destination. They would most likely be indistinguishable from a conventional warhead until they detonate.
The problem is the detonation there are sniffers and imagers all over Europe that look for specific radiation and a double pulse. Some theories include a suspicion that those systems start the retaliation timer if they aren’t stopped it goes automatically and can’t be stopped once it starts.
