2. SAGDEEV CALLED ON THE U.S. TO MAKE A RECIPROCAL GESTURE. In a recent speech in London, the irrepressible former head of the Soviet Space Research Institute noted that the Soviet Government has offered to convert its gigantic Krasnoyarsk radar in Siberia into an international space research facility in response to US complaints that the radar would violate the ABM treaty. Sagdeev suggested that the US reciprocate by turning the unfinished US embassy in Moscow into a nuclear crisis reduction center. The communication system, he pointed out, is already in place.
