I read that the US has new language about first strike nuclear weapons I think The use of tactical nuclear missiles as bunker busters has been described
Like the sticky tape radiation tank neutralizer this idea prevents the use of tactical nuclear missiles
a slow lumbering cargo plane full of
Cobalt arrives at the predicted target just as the nuclear weapon arrives; this works as even at 1000 Km PH The defender has minutes to figure out which near target area the missile will strike
when the bunker buster missile reaches target plus the cobalt filled cargo plane it creates a huge plume of hyperlethal Co (the doomesday bomb scenario used cobalt bombs) which completely irritates the neighboring countries causing diplomatic fail plus huge fiscal reparations
thus making the tactical nukes Objectively useless
If you nuke one county even lightly the neighbors get poisoned ruining decades or centuries of possible diplomacy
A variant on this is to use very cheap sodium fluoride plus sodium chloride plus charcoal This combo when turned to plasma vicinal to a nuclear blast turns to a multiton ozone destroying greenhouse gas hyperemission If the nuke is predictable enough flying the NaFNaClC cargo just above the blast ejects the toxic ions to the stratosphere where they act as Ozone depleters plus greenhouse gases
Now arguably this is only a few dozen tons of of prechlorfluorocarbons per nuke yet the 2004 global output of CFCs was limited to just 70 tons Thus it might be possible to eject a full years worth of banned ozone destroyers per tactrical nuke intercepted They could describe this to defensive use as HalonDefenseShield
again each tactic nuke creates such global irritation as to make it more of an objectibe liability than objective benefit
There is the risk that a multiweapon nuclear war Together with predictable targets each wearing a halondefenseshield could destroy the earths ozone layer plus create severe greenhouse gas effects
Thus deterring even moderate dose nuclear war as MAD
Thus they could like lower taxes n we could spend all that military money on ice cream
