> But General Petraeus already commented how the response would be a collective NATO involvement sinking the Russian Black Sea fleet and bombardment of Russian positions in Ukraine.

General Petraeus is a retiree who didn’t officially speak for NATO or the US government. That gives NATO and the US government some wiggle room.

My guess is that that’s a possible response, but not a guaranteed one. Let’s say there’s a detonation high above the Black Sea with zero direct victims and a prognosis of very few indirect victims due to long term effects of radiation (effectively more fireworks than weapon). I don’t see NATO or the US government sinking the entire Russian Black Sea fleet for that. But who knows?
