Project Clear Vision
Project Clear Vision was a covert investigation of soviet-built biological bomblets conducted by the Battelle Memorial Institute under contract with the CIA. The legality of this project under the Biological Weapons Convention is highly disputed.
The project was completed during the Clinton Administration, but its existence was revealed by the New York Times in August, 2001 during the Bush Administration [1]. The project's stated goal was to assess agent dissemination characteristics of the bomblets [2]. Despite this "defensive" aspect, the project's findings can probably be used in a covert bioweapons program.
As part of the Biological Weapons Convention, the United States committed not to develop bioweapons. Moreover, the United States had not reported the secret projects in its annual confidence-building measure (CBM) declarations [3].
