But the pro-democratic policies of glasnost and perestroika that I unveiled in the mid-1980's did not appear out of thin air. They arose from Nikita Khrushchev's reforms of the 1950's and 1960's, and from Alexei Kosygin's reforms later on.
归根结底，是苏联发生的革命导致了冷战的终结。但20世纪80年代中期我所倡导的改革和开放的民主政策也绝非凭空而来，其根源就在于20世纪五六十年代尼基塔赫鲁晓夫、还有后来柯西金所做的改革努力。
