The Dead Hand

When Gorbachev announced a unilateral Soviet moratorium on testing in 1985, marking forty years since Hiroshima, he challenged the United States to follow suit. Gorbachev hoped the moratorium would crimp research for Reagan’s Strategic Defense Initiative. Tests would be needed to develop an effective nuclear-pumped X-ray laser. “If there is no testing, there will be no SDI,” Chernyaev wrote.⁴⁶ Reagan refused to go along with Gorbachev’s moratorium, saying a test ban could not be effectively verified. Thus, the dispute over “verification,” whether or not a test ban was being observed, became both a scientific and political issue. Reagan had a second reason for refusing to go along with Gorbachev: American designers wanted to test a new generation of warheads that would be able to survive the radiation effects of a nuclear blast.⁴⁷ Gorbachev’s moratorium was brushed off as propaganda. From 1949 until the start of the moratorium, the Soviet Union had carried out 628 nuclear explosions, 421 of them at the remote Semipalatinsk test site in Kazakhstan in Central Asia. The United States had carried out its 978th test, code-named Jefferson, just days before Chernobyl.⁴⁸

By the spring of 1986, Gorbachev was under pressure from the Soviet nuclear weapons establishment to resume testing. His peace overture, the unilateral moratorium, had borne no results. “It is hard to tell when the new thinking will arrive,” he lamented in a meeting with advisers. “But it will come, and maybe unexpectedly fast.”

In those exhausting days, Velikhov, the open-minded physicist, once again showed the way. His contacts in the West proved critical. Velikhov knew of Americans outside the U.S. government who were skeptical of Reagan’s policies and who were independent thinkers. One of them was Frank von Hippel, a physicist and professor of public and international affairs at Princeton University, who was chairman of the Federation of American Scientists. The group was founded in 1945 by atomic scientists concerned about control of the technology they had helped create, and von Hippel practiced what he called “public interest science,” attempting to influence government policy. In the early 1980s, he was caught up in the nuclear freeze movement and sought to provide an analytical basis for some of its initiatives. He had met Velikhov several times at conferences, and they enjoyed brainstorming together.⁴⁹ Riding together in the back of a bus at a conference in Copenhagen, Velikhov suggested to von Hippel: perhaps independent, nongovernment scientists from the United States could help demonstrate the feasibility of seismic verification, which had deadlocked the superpowers?⁵⁰

A similar notion was gaining ground among American scientists. One who was keenly interested in building such a bridge was Thomas B. Cochran of the Natural Resources Defense Council, an environmental group. Cochran, a nuclear specialist who had opposed the U.S. plutonium breeder reactor program in the 1970s, was digging into evidence of secret U.S. nuclear tests. When Reagan came into office, he became interested in branching out from strictly environmental issues. In March 1986, Cochran was attending a Federation of American Scientists conference in Virginia. During a coffee break, he talked with von Hippel about a seismic verification experiment.

Then, in April, von Hippel was in Moscow and sought out Velikhov. “Do you have any good ideas?” Velikhov asked him, as he always did when he met the Americans. Velikhov was disorganized—von Hippel once found his desk drawer filled with unsorted business cards—but he restlessly sought new ideas. Velikhov and von Hippel decided to hold a workshop in Moscow on seismic monitoring. Three different proposals were aired at the workshop, held in May. A few days after the workshop ended, Velikhov, a vice president of the Academy of Sciences, signed an agreement with Cochran’s group to allow a team to position seismic monitoring equipment adjacent to the Semipalatinsk nuclear weapons test site.⁵¹ This was one of the Soviet crown jewels, the counterpart to the Nevada Test Site. Velikhov urged Cochran to get back within a month; the test moratorium was scheduled to expire soon. They needed to do something big to help Gorbachev keep the moratorium in place.

There was just one hitch: Velikhov did not have official permission for the Americans to make the trip to such a secret location. (The Semipalatinsk site was totally closed; during the Cold War, the United States deployed radioactivity-sniffing aircraft and other methods to monitor Soviet weapons tests.) Velikhov took a gamble—if Cochran could somehow show verification was possible, it would strengthen Gorbachev’s hand in prolonging the moratorium.

The Scripps Institution of Oceanography loaned the first seismic gear, relatively unsophisticated surface monitors. Cochran and his team lugged them to Moscow in early July.⁵² The plan was to set them up at three locations outside of Semipalatinsk, within 150–200 kilometers from the center of the testing area, but not actually on the site. The Soviets were not conducting tests at the time. Cochran’s goal was simply to show that the Soviets would allow American seismologists to set up stations inside the Soviet Union, record data, and bring it out. This would be immensely symbolic, calling into question the Reagan argument that a test ban could not be verified, and helping support Velikhov’s effort to get Gorbachev to extend the moratorium.⁵³

The American team arrived in Moscow on July 5, but before they could unpack their equipment, Velikhov ran into trouble.

“All of our military was completely against it,” Velikhov said. Gorbachev got cold feet and decided to ask the Politburo to rule whether Velikhov could allow the Americans to get close to the secret test site. The Soviet leadership was still struggling with the Chernobyl aftermath. “It was a very, very tense meeting on Chernobyl,” Velikhov recalled. “And after this meeting, everybody was tired, and there was a discussion of Semipalatinsk. Gorbachev was tired, and as usual, he wished somebody else would make this decision, not him. I made the case, but he didn’t give me any indication of strong support.”

Then, abruptly, two prominent figures turned against Velikhov. They were Dobrynin, the former ambassador to the United States, and Zaikov, the Politburo member for the military-industrial complex. They demanded: Why isn’t the measuring reciprocal? Why are we not putting our equipment in Nevada at the American test site?

Look, replied Velikhov impatiently, you have it all wrong. Reagan wants to continue testing. We are trying to impose a moratorium. We should help the scientists who will show the world that a test ban can be verified!

“After the meeting, it was inconclusive,” Velikhov recalled. He had no authority to sign the papers and give permission to Cochran. When the meeting was over, Velikhov was sitting with Gorbachev. What should he do?

Gorbachev replied, in his maddeningly vague way: “Follow the line of discussion of the meeting.”

“As I understood it?” Velikhov asked.

“Yes,” said Gorbachev.

Velikhov took that to mean “yes.” He gave a green light to Cochran’s team. The only condition, apparently to satisfy the military, was that the American scientists turn off their monitors in the event of any Soviet weapons test. Cochran agreed.⁵⁴ The team began to set up the first station on July 9. It was an amazing moment, a toe into a closed zone, accomplished by an environmental group, not by the United States government. It demonstrated that scientists could, on their own, break through the Cold War secrecy and mistrust. It also underscored the unusual clout of Velikhov. “Not only his clout,” Cochran said, “but his chutzpah.”⁵⁵

When Cochran, von Hippel, Velikhov and other scientists went to Gorbachev’s offices at the Central Committee in Moscow on July 14, they urged him to extend the moratorium. Cochran carried back from the test site the first seismic record, made by a scratchy needle moving across smoked paper fastened to a drum recording device. Pravda played up the meeting in a front-page article the next morning.

A few days later, on July 18, former president Richard Nixon held a private talk with Gorbachev in Moscow. Gorbachev told Nixon he wanted to send a signal to Reagan: he was eager to move ahead, he would not seek to postpone action until Reagan left office. “In today’s tense atmosphere, it means we cannot afford to wait,” Gorbachev said. Nixon reinforced the idea, saying Reagan was also primed to move. Nixon transmitted the message to Reagan, writing up a twenty-six-page memo for the president on his return.

On July 25, Reagan sent Gorbachev a seven-page formal letter, an outgrowth of the meeting at which Weinberger had proposed eliminating all ballistic missiles. The language of the Reagan letter was convoluted. It proposed that either the United States or the Soviet Union could research missile defense, and if they succeeded in creating it, would share, but only if both sides also agreed on a radical idea: “eliminate the offensive ballistic missiles of both sides.” If they didn’t agree to share-and-eliminate, then either side could, after six months, build missile defense on its own. Thus, Reagan had taken his dream of missile defense and hammered it together with Weinberger’s improbable proposal to get rid of the missiles.

On testing, Reagan firmly refused to stop.
