As the world frets over Iran's and North Korea's nuclear programs, a more sizable nuclear issue is garnering little notice. The United States and Russia began negotiating further modest reductions in their nuclear arsenals earlier this year, with the latest round of meetings expected next week. Despite their progress, the negotiations have failed to address a fundamental question: Does it make any sense to cut down weapons stocks when we don't even know just how many there are -- and where?
The United States and Russia have by far the world's largest nuclear weapons stockpiles, with approximately 5,000 and 13,000 operational and reserve warheads, respectively. (North Korea's Kim Jong Il, by contrast, has a handful of weapons at most). Since the Strategic Arms Reduction Treaty (START) was signed in 1991, Washington and Moscow have regularly exchanged data on their arsenals and conducted inspections, taking some of the guesswork out of assessing the two countries' capabilities. But these measures have only scratched the surface. START is primarily concerned with accounting for nuclear launchers--ballistic missiles and bombers--and does very little to account for all nuclear warheads. Such limited transparency in U.S. and Russian stockpiles contributes only modestly to global security.
Far from being a formality, disclosures about nuclear stocks provide a measure of security in their own right. Potential adversaries who know the capabilities of their opponents are more likely to make sensible threat assessments and less likely to overreact. Data about a country's arsenal would also reassure others about its intentions. If their scope were broadened and accompanied by more stringent verification, data exchanges could profoundly affect U.S.-Russia relations.
Imagine, for example, if each country knew the location and status of the other's complete stockpile of warheads. With the right cataloging technology in place, each could be reasonably confident that the other was not preparing a pre-emptive nuclear attack against it -- one lingering concern in negotiations today. Achieving this type of transparency would necessitate the registration, verification, and tracking of all warheads such that both countries could monitor their positions in real time. If one country attempted to move or deploy weapons, the other would notice -- a check that would likely prevent any such action from taking place. Further technical work would be needed to ensure that neither side could cheat. But the sooner such a system is in place, the sooner confidence between the two nuclear powers will grow.
