And how many of those were they actually lunch by that I mean problems with the missile the Warhead guidance not take it out on the first strike
Yeah, those R-7 and R-16 missiles were not great on guidance, but holy cow, those were large bombs on top of them. 3-6 MTs. You don't need to get super close to your target. If any of them do get launched, given how dense the east coast is, they're going to kill a ton of Americans.
Even if "only" 5-6 get through you're playing roulette with Soviet targeting and the civilian populations next to them. You take 10 hits in the wrong places and the US is knocked back pretty bad on the development side.
Also, it's easy for us to say, "yeah, we'd win the conflict and end the nuclear threat," but we're also not the ones getting reading to sneak attack SIOP-62 on someone and know we've committed something close to genocide.
