nonproliferation
     n : the prevention of something increasing or spreading
         (especially the prevention of an increase in the number
         of countries possessing nuclear weapons); "they protested
         that the nonproliferation treaty was just a plot to
         maintain the hegemony of those who already had nuclear
         weapons"; "nuclear disarmament and nonproliferation are
         closely related goals" [syn: {non-proliferation}] [ant: {proliferation},
