By the late 1980s, with the Cold War ending, teams of U.S. and Soviet biological warfare experts prepared to visit each other's laboratories to see for themselves.
On Dec. 11, 1991, Alibek and his Soviet colleagues traveled to Ft. Detrick, Md., home to the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID), where researchers studied how to protect troops from germ warfare, work that was allowed under the 1972 agreement. And Alibek began making personal connections that would soon ease his transition to American life.
None would prove more important to him than his rapport with USAMRIID director Charles L. Bailey, an entomologist and U.S. Army colonel.
Within a year, Alibek resigned from Biopreparat and fled to the U.S. with his wife and three children. Bailey retired from the Army but stayed at Ft. Detrick as an analyst with the U.S. Defense Intelligence Agency.
Bailey's job was to assess what the Russians were up to.
This gave him a close view of Alibek's confidential debriefings with U.S. intelligence agents. The debriefings, Bailey said, provided "very valuable" information about the Russian program. Alibek described threats beyond the Russian borders.
"Alibek thought that every country that had anthrax" also had smallpox, including Iraq, Iran and North Korea, Bailey said.
In the mid-1990s, when Bailey went to work for a Huntsville, Ala., company with defense and intelligence contracts, Alibek visited frequently. They shared meals, attended horse shows. Alibek seemed to enjoy learning about American life.
"He was easy to like," Bailey recalled. "We became friends."
They also became a commercially sought-after team.
"I helped to build Alibek's reputation with the military," Bailey said. "A lot of people were impressed with Alibek. I was impressed."
The Alabama company also hired Alibek as a consultant, and asked him to compose a history of the Soviet program that could be used by the intelligence community.
In 1997, the two worked together for Battelle, a large nonprofit research and development organization. Next, they moved to Virginia-based Hadron Inc., another firm that had ties to U.S. intelligence agencies. Alibek also circulated among government officials. He privately briefed Gen. Joseph W. Ralston, then vice chairman of the Joints Chiefs of Staff, the nation's second-highest military officer.
