The development of tactical nuclear weapons by one state would lead to a new global arms race.  When one state develops a new military technology that could potentially tip the strategic balance in its favor, other countries are quick to take notice and to attempt to develop the technology themselves. During the Cold War, the nuclear arms race between the United States and Soviet Union reached a fever pitch, with both states spending vast quantities of money and resources to build newer, deadlier, and ever more plentiful nuclear arsenals. Since the dissolution of the Soviet Union, however, the nuclear arms race has been at low ebb. Recent moves by the United States, as well as Russia and China, to develop newer, smaller nuclear weapons, as well as to open discussion of tactical application of such weapons outside the paradigm of MAD, however, threaten to bring the nuclear arms race into the 21st century1. If nuclear weapons begin to permeate the tactical decisions of states, from use in bunker-busting to destroying armor formations, they will cease to hold the special power of fear that has kept them from ever being employed in combat since World War II. A race to develop easier to use, less accountable weapons, while eroding the taboo against their use, spells a recipe for disaster. 1 Jervis, Robert. 2001. "Weapons Without Purpose?
