I think the article is naive in the sense that NATO has done everything in its hands to steer and asure everyone in the world that this is absolutely a regional conflict, nothing to be worry about, nobody is going to globally deploy any force to handle anything, because you don't need to mobilize a dozen of armies resources for a fairly local conflict, even if the conflict involves a potencially hostile - to NATO - nuclear power. Hence, MAD is not present in most of the scenarios probably evaluated in some tables around the globe. Even here, I think nobody is even mentioning great chances of a massive nuclear confrontation. So, Russia has the upper hand in the game, and there's no MAD as a variable. So perspectives look awry from going towards a clean exit from the conflict. Nuclear options, are just of the several bad outcomes for EU. I think by now NATO has lost the war and Ukraine is by itself, most probably any further military, intelligence assistant directly regarding about regaining control of the south of their country is being re-assesed right now. They probably know they will have the lines of cooperation open just a couple more of hours till they fall to silence, and they will try to exact the most advances possible in this grim situation, for those lines would probably be stable for years, as it happened with Crimea.
