A 50-200 KT warhead would wipe DC off the map. So not sure where your getting at. You don't need a large warhead to wipe a city clean off the map. AGAIN ONLY REASON WE HAD large yeilds **was** (past tense) to make up for inaccuracy.whether twenty 855 KT nukes or they use a single 20 MT nuke, you can be certain Russia wants to wipe it off the map
A small yield warhead with good precision does do just as much damage if not more then a inaccurate large yield warhead....
It is that simple. Stop trying to contemplate something that isn't in existence anymore. A few precision 50-200 KT warheads do more damage to a region then a single 20 MT warhead. Which is why large yield weapons are a thing of the past. Not to mention large yeild warheads are really god danm pricy to upkeep & build.
I keep laying down stone cold facts on repeat like a broken record but entirely blindly ignored and responded with fantasies based on scenarios that have not existed for us in many many decades.... can we stop and start discussing real possibilities for CURRENT TIMES. This isn't the 70's or 80's anymore. The entire worlds nuclear arsenal has drastically changed entirely into smaller more precision based weapons.
