As an American citizen, I'm very glad this wasn't treated as indistinguishable from a nuclear attack. I regret that no one was held accountable for initiating the war, but MAD would have been bad news.
I was and am against those wars, but I am not a pacifist. If a war is a 'just way' and should be fought (there's a whole scholarship on when wars are just, I have a high bar, but it can be met), there will always be targets that are 'dual use' and in that regrettable circumstance in my mind, those would be legitimate targets after a very careful calculus was made to weigh lives lost and saved by destroying them.
Most American military experts assumed the Russians would have started the war with a much more aggressive arial bombardment. It's just kind of how these things are done. I assume them doing this now is Russia paving the way for a more traditional operation to begin when the ground freezes. It's going to be a bloody winter. It's a tragedy.
