Where do you see the features of the socio-political development of the USSR in the mid-60s and mid-80s?

From the 60s to the mid 80s, there was “stagnation” in the Soviet Union. This is a period of relative economic and political stability and peace that began after the departure of Khrushchev and the coming to power of the party beau monde headed by Leonid I. Brezhnev. A feature of this time can be called the development of culture and art, cinema and sports, and the parallel struggle against the dissent of their citizens in the countries of the socialist camp. A feature of this period was the massive outflow of the Jewish population from the USSR to Israel, which began in the 70s.
