There is no real risk of a new global arms race arising from the development of tactical nuclear weapons. No country is suggesting, nor would ever likely suggest, a relaxing of controls on the use of nuclear weapons. Tactical nuclear weapons are simply more advanced, more discriminating nuclear weapons. They would not be used except in the utmost extremity, as with all nuclear weapons. While tactical nuclear weapons may find greater applicability in the field, it does not mean they would result in a new arms race.
