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.

In May, North Korean leaders hinted to visiting U.S scholar John W. Lewis that they're willing to resume negotiations with the United States on nuclear arms. But if those talks are revived, North Korea wants to focus on mutual steps toward a denuclearized Korean peninsula. The Bush administration has said repeatedly it doesn't want to depart from six-way nuclear talks. (Mike Shuster's full report on NPR's Morning Edition is linked below.)

Daniel Sneider writes, "There is a small crack in the otherwise closed door between the United States and North Korea. That is part of the message Stanford Professor John W. Lewis, an expert on Northeast Asian security issues, brought back this past week from a visit to China and North Korea." (Sneider's column, "Window is closing for U.S. in N. Korean nuclear talks," is linked below.)

On May 18 a roundtable organized jointly by CDDRL and CREEES and chaired by SIIS Senior Fellow Gail W. Lapidus brought together visiting scholars Temuri Yakobashvili from Georgia, Volodymyr Kulyk from Ukraine, Uladzimir Rouda from Belarus, and Wall Street Journal reporter Steve LeVine to examine the dramatic wave of democratic revolutions and protest movements which have transformed the geopolitics of the post-Soviet region over the past 2 years.

The participants argued that although the "Rose Revolution"in Georgia in October 2003, the Ukrainian "Orange Revolution" of November-December 2004, and the more recent regime change in Kyrgyzstan were all precipitated by popular protest against fraudulent elections, they expressed a deeper dissatisfaction with the widespread corruption and failures of the three governments, combined with the emergence of an increasingly mature and organized political opposition. While international organizations and actors played a supportive role in delegitimizing electoral fraud and nurturing civil society, domestic factors were the decisive ones in bringing about peaceful regime change.

The panelists also concurred that the "easy"revolts were now over. They predicted that future upheavals in the region were inevitable, but were far less likely to go smoothly. In Belarus, although popular hostility to a tyrannical political regime is growing, inspired by the successful example of neighboring Ukraine and the attraction of Europe, the absence of a united and organized opposition remains a major barrier. In Uzbekistan, the repressive regime of President Karimov has demonstrated its willingness to resort to violence to put down opposition, and to forestall international criticism by stigmatizing opponents as Islamist terrorists.
