So the confrontational is more because of the perceived shift to offensive ("unprovoked") first strike over "defensive" second strike, rather than any perceived loss of a deterrent second strike capability?
As I understood it yes. The ability to disarm the other side at will, and prevent any retaliation against cities, was seen as an more offensive capacity
Just want to note that the front page top 10 - 15 the last 24 hours or so has been disproportionately full of US government and military related posts. Something must be coming, some big news. BOLO
