December 3, 1999 Another view on CTBT: Sandia consultant Richard Garwin makes the case for the treaty rejected by the U.S. Senate Richard L. Garwin 11/23/99 speech at Sandia National Laboratories Published in Sandia Lab News 12/03/99 (article by Bill Murphy) An overflow audience of Sandians at the CNSAC auditorium last week heard distinguished scientist and Sandia consultant Richard Garwin express a view of the Comprehensive Test Ban Treaty (CTBT) sharply at odds with the position articulated by Sandia President C. Paul Robinson in recent congressional testimony. Paul testified in a widely publicized Senate hearing that the safety and reliability of the nation's nuclear arsenal might not be assured under CTBT. Directors of Los Alamos and Lawrence Livermore national labs also expressed concerns about problems they believe are associated with the treaty. The testimony of the lab directors was seen as a critical factor in the Senate's rejection of the treaty, which was negotiated by the Clinton Administration and signed by the president in 1996. "If the United States scrupulously restricts itself to zero yield (as stipulated in the treaty) while other nations may conduct experiments up to the threshold of international detectability, we will be at an intolerable disadvantage," Paul testified in October. "I would advise against accepting limitations that permit such asymmetry." Garwin, who testified before the Senate in favor of the treaty, explained his position during a colloquium at Sandia titled "Nuclear Weapons in the 21st Century." Based on comments from Garwin and Paul, it is clear that both men believe the U.S. position on CTBT pivots on a point that Paul expressed in his Senate testimony: "Whether on balance the effect of a test ban to retard proliferation and further development of nuclear weapons is worth a similar penalty on the U.S. nuclear arsenal is the real crux of the dilemma ... You (senators) must form a judgment whether the Comprehensive Test Ban Treaty will serve to enhance, or to diminish, national and global security." Garwin told Sandians that in his view international treaties-- specifically the Limited Test Ban Treaty (LTBT) signed in 1963 and the Non-Proliferation Treaty (NPT) of 1970-- have played a vital role in keeping nuclear proliferation as low as it has been. In 1962, Garwin said, it was widely believed by national security analysts that there would be 20 or more proliferant states within two decades. That estimate turned out to be highly inflated. "I believe," he said, "that it is the banning of tests in the atmosphere (LTBT) of 1963 and the Non-Proliferation Treaty that have kept the number of such states small, together with the shelter of NATO and the U.S.-Japan alliance." Likewise, he said, the CTBT is critical for the success of non-proliferation goals in the 21st century. On the other hand, he said, testing and retesting proven weapon designs don't add that much to the confidence level in the stockpile. "The future of the Non-Proliferation Treaty depends on the Comprehensive Test Ban Treaty, which the Senate rejected ... In declining to consent to ratification of (the treaty), senators argued that Russia and China would conduct clandestine nuclear weapon explosive tests in violation of the zero-threshold CTBT; that proliferant states would not join the treaty and could test openly; that the international monitoring system, even supplemented by U.S. intelligence, might not detect the smallest tests; and that the U.S. nuclear stockpile could not be maintained safe and reliable without nuclear explosion testing." Garwin asserted that nuclear weapons tests that cannot be detected confidently under the Comprehensive Test Ban Treaty would not militarily disadvantage the U.S.. Further, he argued that a $4.5 billion stockpile stewardship program of surveillance, analysis, and remanufacture will maintain U.S. nuclear weapons in pristine state for many decades. Full nuclear weapons tests, he said, are not nearly as important for guaranteeing the security of the stockpile as would be a systematic program of remanufacture, in which existing, proven weapons would be kept in essentially new condition. "The Comprehensive Test Ban Treaty cannot enter into force without U.S. ratification," Garwin said. "Beyond that, it needs the signatures of India, Pakistan, and North Korea. Former ambassadors to India and Pakistan, Frank Wisner and Bob Oakley, write that without U.S. ratification, India will test further to develop a true thermonuclear weapon, and Pakistan will match India's tests one for one ..." "The U.S. has by far the greatest and most flexible military capability in the world, and its nuclear weapon technology is the most advanced. More than 1,000 U.S. nuclear explosion tests contributed to this technological lead. But effective nuclear weapons of 1957 vintage (or even fission weapons of 1950) are enough to destroy millions of people. This threat cannot be countered by further nuclear weapons development and nuclear tests. It must be constrained by arms control, by deterrence of acquisition or of use of nuclear weapons, and if necessary by destruction of the nuclear weapons before they can be used, or by defense against their delivery." Here are some other points Garwin made during an hour-long talk: o The greatest threat to U.S. and global security is the enormous Russian nuclear arsenal. Strengthening Russian control, reducing the size of the arsenal, and erecting higher barriers to its leakage are the highest priority. o If relations between the U.S. and China should deteriorate to downright enmity, as might occur through initiatives on the Chinese side or gratuitously by demonizing China, China could evolve to pose a serious threat. This is far better averted than countered. o The U.S. must exert every effort to bring India and Pakistan into the CTBT. An "urgent and feasible U.S. agenda" for reducing the nuclear threat in a multipolar world would include: o Recognition that U.S. security is secured more by limiting the threat than by increasing U.S. arms. o Proper hearings leading to a better understanding of the CTBT, and its ratification and entry into force. o Extending the Strategic Arms Reduction Treaty regime with Russia to include all nuclear warheads and nuclear weapon-usable materials, and limiting the total to 2,000 warhead equivalent on each side. o Just as the U.S. commitment to NATO and to the security of Japan has facilitated Germany and Japan's non-nuclear weapon state-status, so would a commitment of U.S. and other nuclear weapon states, through the UN or regional agreements, to provide security guarantees of non-nuclear states against nuclear attack.
