I‘m not convinced that the West would do anything beyond further sanctions and lethal aid if Russia set off a dirty bomb. I honestly don’t think there is anything Russia can do within Ukraine that would provoke NATO to attack Russia. NATO is defensive, a full on nuclear strike to flatten Kyiv will not get the consensus to attack. Russia could launch a new Holodomor with Einsatzgruppen and gas chambers et al, publicly murdering Ukrainian women and children by the hundreds of thousands, stacking the bodies like sandbags in front of CNN and BBC cameras, and still NATO won’t do more than increase arms support to Ukraine. This is Ukraine’s war to win or loose, though maybe by that point Germany will finally release Leopard 2s.Ukraine might get better air defenses or longer missiles but I doubt they'd get direct intervention.
