I agree, NATO will never respond with nukes, even if a nuke is launched directly into NATO territory. NATO understands this is a 0 sum outcome. And it's not needed.

I think the risk is that those around Putin (regime), and Putin himself to an extent, believe that a world without Russia is not worth having. And to the regime, Putin is Russia and Russia is Putin. The question is, if there is a 100% chance that should he lose this conflict that his regime will collapse and a 99% chance that Russia could survive a nuclear war on equal footing with the west which will he choose?

Even a full scale nuclear war will not end the world, many millions, likely billions will survive. It will just be nothing like the world before.

MAD is there for a reason, anyone who thinks that a nuclear attack within territory of a NATO country or forces within the areas that fall under Article 5 won’t trigger a nuclear response is kidding themselves.

And not only that eroding the threat of MAD makes the world a far dangerous place because it makes a first strike more likely.

That said even if the conflict goes nuclear there are different levels of escalation a targeted nuclear attack on say a military target would likely trigger a proportional response even if it’s a nuclear one.

And outside of NATO the US would very likely respond with a retaliatory nuclear strike against a nuclear strike on its forces where ever they might be.

The point is that they don't "need" to respond with nukes. They can trigger article 5 and start a conventional war and achieve the same or better outcome; possibly without even putting boots on the ground. For example, NATO could (likely) sink the remainder of Russia's Black Sea fleet within a few days of triggering article 5. And/or they could actually establish a no fly zone and be fully justified in doing so.

Responding with a full on nuclear assault because someone first strikes with a Nuke that's smaller then those used in WWII doesn't make sense. You can probably do more damage with chemical, biological, or cyber warfare then a nuke like that (unless targeted at a dense population center).
