There are obviously a lot of ways to look at the war between Russia and Ukraine, but if we are looking at it from its geopolitical antagonism with NATO, then it needs to be understood as a conflict that the West has wanted and taken action to foment for decades. Some people speak of Russia invading Ukraine as if it was something done on a whim rather than a military action that was at least viewed as necessary for Russian national security. While the invasion soured Russia's image and has ruined relations with some bordering countries, Russia almost certainly didn't see any other course of action other than invasion due to the threat of NATO encirclement along with the western puppet government of Ukraine. Regardless of the goals of diminishing NATO or not, this conflict was a seemingly inevitable proxy war between NATO and Russia following Maidan. The fact that the war is happening at all is a victory for NATO and the west because it means they've driven a semi-permanent wedge between Russia and Ukraine, at this point its about limiting further NATO gains. I find it deeply tragic that there weren't diplomatic ways to ensure the security of both Ukraine and Russia and wish that the war wasn't deemed necessary, add it to the list of post-soviet tragedies.

All that said, if we are discussing how this conflict relates to the dissolution of NATO. I don't think it does, at least not immediately or directly which is why I think the sooner the war is over the better. Russia is most a threat to the imperial core through providing military support to anti-imperialist efforts like those in West Africa, but they can't ignore dangerous western provocation in neighboring countries either.
