NEGATIVE DETERRENCE GOOD/BAD
A critical argument whenever nuclear weapons are discussed is whether their use is so terrible that they will never be used. This is the doctrine of deterrence. It states that no one will use nuclear weapons against a state with nuclear weapons because the result would be mutual destruction, thus the name of the often mentioned Mutually Assured Derstruction (MAD) doctrine.
If deterrence arguments are true, nuclear weapons stop military attack and assure peace. If deterrence arguments are true, no one will attack the USA with a WMD. If deterrence arguments arwe falsem the nuclear situation we find oursrelves in is highly dangerous, with a catastrophic nuclear war bound to happen eventually.
