Actually they have 12 nuclear subs... And the west knows where all of them are... Those would obviously all be eliminated immediately in coordination with an air and land based missile assault.
NATO has strategic nukes in place that can hit all of it’s enemies in less then a minute... By the time they realize they are under attack... It will be much too late for them to mount any response.
There two reasons why MAD has worked... The number one reason... Russia and China haven’t got a chance. The second reason... The west has been benevolent... If they decided not to be benevolent, Russia and China would be obliterated in very short order.
Quite the bloodthirsty nuclear warmonger, aren’t ya?
