What change in warfare does the possession of WMD introduce?

The possession of weapons of mass destruction (WMD) fundamentally alters the nature of warfare, primarily by introducing the risk of total annihilation. WMD, such as nuclear, chemical, or biological weapons, have the capacity to cause massive destruction and loss of life on an unprecedented scale, threatening entire populations rather than just opposing military forces. This capability can deter nations from entering into conventional warfare, as the potential consequences of using WMD could lead to catastrophic outcomes not just for the combatants involved but for the entire world, making total annihilation a looming possibility.

In contrast to options that suggest a reliance on ground troops or naval power, the nature of WMD leads to a strategic emphasis where the mere existence of such weapons can prevent conflicts through deterrence, rather than facilitate traditional military engagements. Thus, when WMD are in play, the focus shifts from conventional military tactics to considerations of survival and the implications of their use, reaffirming the correct understanding of the change they introduce in warfare.
