Mutual assured destruction, as a policy doctrine, is based on the fact that in the event two enemies, engaging in the full scale use of high yield nuclear weapons, would result in the utter destruction of both the attacker and defender. In order for this condition to exist, certain conditions must apply:
With current treaty reductions on nuclear forces in affect, Russia, China, and the United States can severely damage, but can no longer destroy the other. Smaller nations never had the ability to destroy the other nuclear powers completely, but their capabilities are growing. ABM installations, while intended to defend against rouge nuclear states (North Korea, Iran), can quickly be deployed to defend against attack from larger nuclear powers, further reducing the nuclear affect of such an attack. This being said, with MAD no longer being "Mutually Assured", is the deterrent still in effect? If not, what is to prevent a future nuclear war, or a first use scenario involving an emerging nuclear state?
- A first strike must be unable to destroy the targets ability to respond in kind. The enemies inability to respond means that mutual destruction is not assured and thus the MAD deterrent is weakened or eliminated.
- There can be no ability to defend against such an attack. ABM's, fallout shelters, SDI; all these advances reduce the deterrence of MAD once a significant amount of population, industry, and military is felt to be defended from a strike.
