This is still the best summary and most precise assessment on all one needs to talk about when thinking "nukes" that I have heard about nukes and ukraine war so far. I see nothing to add or substract from that. Thats why I ignore Russian threats on the use of nukes, and would even carry on to dleievr wepaons to Ukraine even if Russia uses smaller nukes.
The onyl worry is not whether Ukraine is psychologically able to handle the impact of a nuke (they will not submit to it), but what the use of nukes would do to the decision making processes in European capitals.
