The nuclear deal reached during President Bush's recent visit to India unleashed a predictable wave of criticism. From editorial and op-ed pages to Congress, led by the left but supported on the right, the administration has been assailed for making a bad bargain.

Under the agreement, which still needs congressional approval, India would open much of its nuclear facilities to international inspections in return for gaining access to the world's supplies of uranium and U.S. nuclear expertise.

The attacks on the deal reflect the view of the nonproliferation lobby -- the experts and policymakers whose central concern is to stop the spread of nuclear weapons. I share their aim. But American arguments against the India deal are misleading and only expose the deep contradictions, if not hypocrisy, of our own nuclear policies.

There are two main criticisms of the agreement: first, it undermines the Nuclear Nonproliferation Treaty, the NPT, and second, it permits, even encourages, India to expand its nuclear weapons production.

The NPT issue is particularly sensitive at a time when the international community is trying to persuade Iran to give up certain nuclear technologies which many nations fear are part of a secret bomb program.

The NPT created two sets of global rules -- one for the five nuclear weapons powers it recognizes (China, the United States, Russia, Britain and France) and another for everyone else. The five, for example, allow only "voluntary'' international safeguards on their civilian nuclear facilities. They have no obligation to open their military programs to any kind of scrutiny. And the NPT places no real limits on their arsenals, other than a vague commitment to reduce and eventually eliminate all nuclear weapons.

The rest must open their nuclear energy programs fully to international inspection and agree never to build bombs. In exchange, they gain access to the peaceful uses of nuclear energy.

Iran -- and North Korea -- made that bargain and can be held to account for breaking the rules. But India consistently regarded that as an unequal trade-off and never signed the NPT; neither did Pakistan and Israel, two other nuclear weapons states.

India's nuclear program is the product of decades of largely indigenous effort; it did not result from secretive proliferation in violation of the NPT.

The deal with India turns the five into six. It treats India as a de facto member of the inner club. The deal would require changes in U.S. law to remove existing restrictions on the transfer of nuclear energy technology, changes that would allow India to be treated no differently from China.

That does not weaken the NPT -- it strengthens it. It brings it more into accord with reality and gives India a stake in a system it had previously rejected as unfair. It paves the way for India to join the Nuclear Suppliers Group, the international organization that controls nuclear exports.

The critics are right that the deal enables India to expand its production of fissile materials to make nuclear warheads. Eight of India's 22 power reactors will remain outside international controls, along with a new breeder reactor. The Indians fought for that exemption because they feel their nuclear arsenal may not be large enough to deter a nuclear first strike by Pakistan or China in the future. Critics fear that with increased access to uranium and limited inspections, India will set off an arms race in South Asia.

Again, the agreement simply treats India like the five. Nonproliferation experts claim that unlike India, however, the five have halted their production of plutonium and highly enriched uranium that could be used to build new weapons. This is true, but misleading.

The five have massive stockpiles of fissile material built up during the Cold War. "If I've got a full pantry, it's easy for me to swear off trips to the supermarket,'' said Michael Levi, an arms-control expert at the Council on Foreign Relations.

Moreover, the United States has embarked on a new program to rebuild its nuclear weapons production capability, including creating new facilities to produce plutonium cores for warheads and to assemble them.

India has agreed to back a global pact to cut off fissile-material production. But the Bush administration does not support a treaty that would actually verify this is taking place. And the U.S. Senate has refused to ratify the Comprehensive Test Ban Treaty that would permanently halt any new testing of nuclear weapons.

A Congress that can support those policies is hardly in a position to challenge the administration's agreement with India. Rather than block the U.S.-India deal, it makes more sense to improve it. This could include reaching agreements for cooperation between the two countries to ensure the safety and security of nuclear facilities, including those for military purposes, suggested Stanford Professor Scott D. Sagan, a leading expert on nuclear safety and nonproliferation. "Reducing the risk of terrorist theft of nuclear materials or weapons in India would also help protect the United States,'' argues Sagan.

Beyond that, the six acknowledged nuclear powers should begin to seriously fulfill their part of the NPT bargain -- to cap fissile-material production, to ban nuclear testing, and to eventually radically reduce stored arsenals of nuclear weapons and materials.

Siegfried S. Hecker, a senior fellow and emeritus director of Los Alamos National Laboratory, will join CISAC as a visiting professor in 2005-2006. He will teach undergraduates and pursue research and policy advising on nuclear proliferation and the security of nuclear weapons stockpiles.

As the Los Alamos director, Hecker advised the U.S. Congress on nuclear security challenges created by the Soviet Union's dissolution. He worked with Russian counterparts to consolidate nuclear weapons from four former Soviet states and to implement new security measures agreed to under the Nunn-Lugar Cooperative Threat Reduction program.

"Russia is the key link to fighting nuclear proliferation," Hecker said. He continues to advise Congress members and staff and to work closely with the Russian Academy of Sciences and the Russian Ministry of Atomic Energy on several cooperative threat reduction programs.

On his arrival this fall, Hecker will be one of two former national lab directors at CISAC. Emeritus Professor Michael M. May formerly directed Lawrence Livermore National Laboratory.

Science magazine announced Hecker's CISAC appointment in its Aug. 5 issue.

Hans Blix, chairman of the International Commission on Weapons of Mass Destruction and former chief weapons inspector in Iraq, said at the Stanford Institute for International Studies' International Day, "Challenges in a New Era," on May 6 that he does not think the world faces a new nuclear arms race. Nuclear risks posed by terrorists and nations like Iran and North Korea could trigger a new nuclear arms race, warned CISAC Co-Director and Stanford professor Scott D. Sagan.

Blix said that there need not be a new arms race if the world diligently pursues diplomacy. Blix's speech attracted a strong response from Sagan, who participated in the same plenary panel titled "Looking Ahead: A New Nuclear Arms Race?" "I think there already is a new and very different kind of nuclear arms race going on," Sagan said. "It is a race between terrorists trying to develop a nuclear weapon and national and international efforts to stop that." As North Korea "race[s] ahead with its own persistent and provocative nuclear program," Sagan said the likelihood that the impoverished country will want to test its weapons or sell them to the highest bidder will increase. "I think Dr. Blix's paper greatly underestimates the threat of nuclear terrorism today," he said.

The exchange was one of many during the one day International Day that attracted hundreds of diplomats, policymakers, faculty and students. Other speakers included Oxford professor Paul Collier, the State Department counselor, Philip Zelikow, and Stonebridge International chairman, Samuel Berger. Zelikow and Berger both spoke on U.S. foreign policy.

The SIIS International Day also included discussion session on topics such as Russia's future, U.S. policy on the Korean peninsula, climate change, our energy future, United Nations reform, responses to infectious diseases, U.S.-European relations, and international criminal justice and security. Participants included both Stanford faculty and invited scholars, policymakers, and journalists.

Coit D. Blacker, director of SIIS, said the International Day, an annual event, will become part of the university's newly launched International Initiative that promotes interdisciplinary research and teaching. He also said the Stanford Institute for International Studies will be renamed the Freeman Spogli Institute for International Studies at Stanford University, effective September 1, in recognition of alumni Bradford Freeman, a member of the university's Board of Trustees, and Ronald Spogli, a member of the SIIS board of visitors, who together donated a lead gift of $50 million to help launch the initiative last month.
