One is or is not. There is no in between, unless it is some new woke phenomenon. Now a tactical nuclear weapon is exactly the same. A tactical weapon is 1 to 10 KT, about the size of Hiroshima. Now if that means anything to a younger generation it should mean the total destruction of a city. Buildings demolished, life as we know it gone in a flash for several mile radius.
A tactical weapon is just a nice renaming of the basic element, a total death machine. It not only demolishes things, living and otherwise, but sends out radioactive clouds that spread their death elements across the planet.
Yes a 50 MT weapon would destroy New York, a few dozen would destroy the planet. That is why they were never used. Back in the 70s it became clear to both sides that they only way to win is not to play that game. Somehow Putin and his ilk are playing with fire and they must be both clueless and willing to lose everything.
It really demands that someone stand and describe the horrors of these weapons and why their only use is not to be used. That someone has yet to be found, either in Washington or Moscow.
