Read between the lines. He's saying "Mess with us, we'll nuke you." They mean it. Putin is desperate enough to do it. Anyone responding to this with Euro-bravado is an idiot. Some of y'all didn't grow up during the cold war and your blind spot is showing. No one wins in a nuclear war.

So what do you think the rational response to the nukebullies should be? Give him all he wants? How are reasonable deterrence preparations "Bravado"?

They never mean it, it's a threatening tactics. Their children live in western countries and their money is there. They wouldn't allow nuking western countries just like that. ESPECIALLY if they know they attacked first. Even their own doctrine doesn't allow using nukes for anything except the direct external threat to their statehood.
