Generate text that refutes this claim: Mutually Assured Destruction breaks down when national missile defense systems are introduced, destabilizing world security:  Nuclear weapons create stability, as described in the doctrine of Mutually Assured Destruction (MAD). Countries with nuclear weapons have no incentive to engage in open military conflict with one another; all recognize that they will suffer destruction if they choose the path of war (Waltz, 1981). If countries have nuclear weapons, fighting simply becomes too costly. This serves to defuse conflicts, and reduce the likelihood of the outbreak of war. When states have nuclear weapons they cannot fight, making the world a more peaceful place. Furthermore, armed with a nuclear deterrent, all states become equal in terms of ability to do harm to one another (Jervis, 2001). If a large state attempts to intimidate or to invade a smaller neighbor, it will be unable to effectively subdue it, since the small state will have the power to seriously injure, or even destroy, the would-be invader with a few well-placed nuclear missiles (Mearsheimer, 1993). The dynamics created by MAD are entirely lost when national missile defense systems are brought into the equation. Anti-ballistic missile missiles effectively eliminate the surety of MAD; it becomes a gamble of whether one’s nuclear arsenal will be able to penetrate the missile shield of the enemy. This increases the chance of a nuclear war, since an aggressor state can count on its missile shield to deflect the second-strike attempted by its opponent. Furthermore, in the case where both states in a conflict have missile defense arrays, as will likely occur as the technology is disseminated, the outbreak of war is also more likely, since each will try to race the other to the ability to counter each other’s offensive and defensive missiles. Clearly, the technology will only destabilize world relations, not offer greater security.

MAD is not an effective means of maintaining world security. It relies upon states being too afraid to ever attack one another with nuclear weapons, but the risk of one doing so remains, irrespective of the doctrine. In terms of deterring conventional warfare, that assumes that the state being attacked would chose mutual destruction over potential, transitory subjugation. MAD has too many inherent risks and raises the very real chance, as weapons amass and proliferate, of their being used (Sagan, 1993). National missile defense systems provide a very real defense against not only full-scale attacks by other states, but against nuclear-capable rogue states, such as North Korea, which is seeking to develop intercontinental ballistic missile technology of its own. Should North Korea ever be able to attack the United States or its allies with nuclear weapons, the world will need the ability to counter it. National missile defense is simply a strategic necessity of the modern world in which nuclear weapons may fall into the hands of unstable, aggressive states who might actually try to use them.
