Launching just one sounds like the primary purpose is for messaging, not taking out whatever single target. They want to remind Europeans that they aren't safe just because they live far away. The west has been getting numb to the constant threats of using nuclear weapons. I believe this launch is to give those threats more weight again.

The US will no longer be a threat to Russian ambitions come January. Expect an urgent fear campaign to get the rest of NATO to no longer want to stick their necks out for Ukraine.

Nah, we're not numb. But the fact of the matter is, we can't change anything and letting him win is not going to work, because what's the alternative? Being subjugated or attacked at a later state?

Putin should not forget however, that "we", the EU, also have Nukes and will retaliate, if push comes to shove. Those threats are meaningless either way.
