Going nuclear because someone sank one of your carriers, or maybe even all of your carriers??????? I don't think so......... what about massive Chinese 'nuclear' response? Then everything south of Alaska would be gone!
If things worked the way you think they work, then none of us would be here, even today...
I doubt they would use this weapon system because it was originally a strategic nuclear weapon. So we can't distinguish if its nuclear armed or conventional. Even Putin himself told the U.S. to cancel the Conventional Trident missile because of possible nuclear exchange. The moment the missile is launched, have to assumed its nuclear. The last thing we need is billions of people dead.
