There are also other destabilizing factors unrelated to which method is used. For example, [[rogue state]]s and [[terrorist]] organizations are not limited to being rational actors, so deterrence theory breaks down against these groups. [[Missile defence]] systems also destabalize deterrence, because they remove the fear of retaliation; which could lead to a possibility of a [[first strike]] attack for a small provocation. Multiple independently targetable reentry vehicle missiles (MIRVed missiles) are also destabalizing, because they make it difficult for an actor to calculate the capability of his opponent. | There are also other destabilizing factors unrelated to which method is used.
