45 years ago, on May 10, 1972, the poet Joseph Brodsky, who had previously been persecuted by the authorities, was summoned to the OVIR and demanded that he immediately emigrate. Otherwise, Brodsky was threatened with "hot days", which could mean interrogations and imprisonment or a mental hospital. The poet agreed to leave and on June 4 left the USSR on an Israeli visa, having been deprived of Soviet citizenship.
