"Diplomatic reciprocity" joke

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.
