Weapons of Mass Destruction

The United States government and legal system have completely distorted the meaning of the term "weapon of mass destruction."  The proper military definition of a weapon of mass destruction can only be a weapon which is at least capable, in principle, of killing more than a million people at a single shot.  This would include most nuclear weapons, some biological agents, and practically no chemical agents.  A WMD is a strategic weapon, not one that can bring down a building.
